Sewer maintenance program - blocking God blocking off the water

 Choose a reasonable repair method can effectively reduce project costs, shorten the construction period and reduce the negative impact on the environment , traffic . Various mechanic method has its own unique side, there are common basic points can learn from each other through . From that point, the classification of trenchless repair technology electrofusion coupling mould  induction, to further understanding and promotion of trenchless repair technology will be beneficial.
 A repair method of classification
 1, according to the useful life can be divided into temporary and long-term repair ( permanent ) repair ;
  2, according to construction methods can be divided into grouting , embedded reinforcing method , coating method, and lined pipe collars law method ;
 3, according to the repair site can be divided into point-like repair and overall repair two major categories ;
 4, according to the purpose of the repair can be divided into anti-leakage type , corrosion -and strengthen the structure type categories.
 Second, the repair methods
 By punctate repairs and repairs to the whole division, is a basic method sewer repair technology classification.
 1 , point-like many pipeline repair damage only occurs at the interface part of the pipeline , if only to repair the interface , which is called point-like repair (SpotRepair). Point into the interface embedded complement repair , grouting , collar law , local cured resin . Many damaged pipelines lives less than a decade , tube structure intact, but the interface leakage . For this type of pipeline repair using point is reasonable . Early point-like repair method is relatively simple, relying on staff access to repair leaks in the pipe directly , it can only be used over 800mm diameter pipes . ( 1 ) Interface embedded complement
 Interface is the application of the first embedded complement trenchless pipe repair technology , first fill material embedded in cement mortar , chiseled after the old joints, finishing with quick dry cement or asbestos cement expansion manually embedded complement . In recent years, chemical materials increased, tar epoxy mortar , polysulfide sealants , polyurethane vinegar began to replace cement mortar. Chemical  mould maker seal material has good flexibility , good resistance to deformation than the cement mortar.
Interface embedded complement although cheap , there is no impact on the flow cross-section , but poor quality stability . If staking cleaning is not clean, not dense embedded complement , these human factors can affect the reliability of the repair . In addition , the interface embedded complement duration is relatively long ( 2 ) grouting
 Through the tube and interface parts soil grouting , plugging groundwater seepage into the pipeline route is yet another point-like repair methods . According to different grouting materials can be divided into two types of cement grouting and chemical grouting ; according to setting mode grouting pipe can be divided into the tube ( outside ) drilling grouting and ground ( down ) two drilling grouting . Grouting from the ground down there is a big blind should not place more than note the note , the note of the ground ( such as the bottom part of the tube ) is difficult to inject enough .
In recent years, small pipe tube grouting technology has also made great progress. The airbag will be closed on both sides of the interface , and then injected into the joints of chemical pulp , chemical pulp curing water swelling soon after plugging leaks . And other engineering methods compared to the relatively poor reliability grouting . Therefore, its use in the United States and Japan are subject to certain restrictions , such as the requirement to conduct post- grouting visit every six months , or leakage should not use more than a certain amount and so on. Grouting is often used as an adjunct or temporary plugging method of application , generally can not use the law as an independent work . Grouting is usually embedded reinforcing method and interface combined effects of ( 3 ) sets of the Tour de France
 Mounting interface sealing collar portion is a common point repair methods . The vast majority of the Tour de France sets quality stability than the embedded reinforcing method is good, and fast construction speed , but the collar method has some influence on the flow. Collar method can be divided into the following categories:
 ① Antao ring scaffolds can be divided into : ordinary steel rings, stainless steel rings , PVC sleeve ring.
 ② Press the seal can be divided into : rubber water seals ( ribbon ) , rubber sealing rings ("O" type ) seals , PE water stop seal ( ribbon ) , polyurethane grouting . ③ by way of installation : can be divided into manual installation ( diameter 800mm and above) and airbags plastic injection mould  installed ( diameter 800mm or less ) .
Rings have been used :
 ① ordinary steel rings : steel rings into the 2-3 valve assembly in the tube , collar lined with rubber water in between the main pipe . Pipeline wrong port or interface injustice often affect the sealing effect , ordinary steel rings easily rust.
 4 ) partial curing resin
  The partial gelling is actually a method for repairing the whole point repair practice , there are two kinds :
  ① artificial fiberglass Interface : personnel into the tube , embedded interfaces do first up , and then in the interface area to do fiberglass liner.
 ② local forming felt tube airbags : filling resin coated tube with a balloon felt so close to the main pipe , and then heat cured with ultraviolet light and other methods . Felt barrel shaped balloon partially whole scene is actually a method of curing localized approach.
  2, the overall repair
  If a pipe repair from start to finish , this is called the overall repair (wholerpair). Overall repair is the entire pipe between two manholes reinforcement repair , this repair can be divided into two categories : one is the coating, and the other is the liner method. Coating method is suitable for the diameter of 800mm or more, anti-corrosion, anti-seepage pipes for the purpose of repair .
Liner can not only repair the pipeline corrosion, seepage and can increase the structural strength of the pipe . Liner construction method is fast , reliable , and therefore has become the mainstream of trenchless sewer repair . But the cost is correspondingly higher loss of some liner construction method is relatively large cross-section of the pipeline .
  ( 1 ) coating method (coating)
   Coating method to enhance the role of the structural strength does not only play a role in anti-corrosion and anti-seepage . Little impact on the pipeline coating method section , the relatively low prices, but long duration, reliability, poor quality , pipeline construction cleaning process , temperature, ventilation , personnel quality will affect the repair quality.

Three typical mold steel to become the market leader in the development of

It is well known in the industry, automobile manufacturing, large stamping equipment, mobile phones and other digital products, injection molding process, mold steel must be used, due to the new requirements to improve product safety and quality, but also quietly die steel  plastic injection mould in upgrading. Automobile mold steel into upgrading product quality to enhance the safety requirements phase, the current mold steel used in some companies can no longer meet the requirements of the new standards, mold steel into a replacement stage, such as automotive stamping companies, need to use better hardness and toughness of steel, while stamping prevent breakage and protect the hardness stampings. All involving injection molding, casting, stamping products, need to use tool steel, at present, due to the technical limitations of the domestic manufacturing industry, most high-quality steel mold needs to rely on foreign imports to fill the gap. Model replacement is tapping tee electrofusion mould  inevitable, because the needs of the community is always moving forward, consumer demand for quality, appearance and other requirements continue to increase, companies can only strive to increase research and development efforts to develop new products to meet the diverse requirements of the market.
Currently, there are three typical steel mold steel flame become the meat and potatoes on the market for sophisticated automotive mold manufacturing, to significantly enhance the quality of sophistication, a wide range of flame hardened steel, thermal sensitivity of small, widely used in various precision manufacturing. Its flexibility and stability, and not deformed. Compared with the precision and flexibility of these two die steel, tool steel is supposed to be economic, it made a pre-hardening process in the factory, due to the current high-end digital products selling, buying directly after processing, reduce heat treatment midway link, save the economic cost, high economic efficiency. Users how to choose mold steel

Plastic mold development is inseparable from the project support

At present, China's consumption of plastic has been ranked first in the world, but per capita consumption is only 1/7 industrial countries, 1/4 Industrial moderately developed countries, this aspect of our existence reflects the gap, on the other hand demonstrated China's industrial and plastic mold industry a huge space for development of plastic. Development of the plastic mold industry must rely on national key construction projects, to develop precision plastic injection molds, mold coverage and large injection mold; simultaneously by accelerating corporate mergers and acquisitions and product upgrading, narrowing the distance between the countries, so  plastic coupler fittings mould that our plastic mold industry sustained and healthy development.
Arbitrariness of large plastic mold steel, carbon steel and 80% of 40Cr steel. For complex, precision molds, in order to avoid heat deformation, usually in annealing, normalizing state or quenched state processing used, so life is only similar foreign molds 1/10 to 1/2. Domestic automobile enterprises are willing to choose plastic mold Germany, Japan, Sweden, three series of die steel, but in the country to buy European steel mold, prices are often higher than the 30% to 40%, seriously affecting the competitiveness of domestic mold. Look at the precision molds, mold manufacturing and life cycle. Japan's auto mold accuracy up to 0.02mm, precision plastic mold parting controlled 0.01mm, while the domestic automobile molds brands, more than 25%, some 50% or more, many companies tend to be most enterprise workers interchangeable in technology and production jobs. Training of trainers and high-end CNC machine operation skills of domestic mold lack of high-tech enterprise employees processing technology, in a way that also affected the utilization of high-end equipment. Die low proportion of technical personnel of enterprises, most enterprises between 15% to 20%, and lower integrated development capability. Mold factory often and materials manufacturers, product manufacturers to develop; injection molding factory with material manufacturers will jointly  pipe reducing coupling mould develop new models; brand plastic vendors and brand car companies jointly developed a new plastic and steel products. Such strong cooperation, so that enterprises have a strong R & D capability. Chinese enterprises in innovation, greater R & D capability gaps. "Luo Hui pointed out that China plastic mold industry in the current and future development, to work closely with key project of the steel, automobile, petrochemical, shipbuilding, light industry, textile, nonferrous metals, electronic information, these nine national defense industries, to enhance large mold, precision injection molds, high-grade standard mold manufacturing capacity; achieve localization tool steel and high quality, improving mold material supply system  injection mould to provide a more comprehensive variety of sizes and grades of material, and greatly reduce mold manufacturing enterprises preparation period; improve mold new materials, new technology and new plastic molding, high strength, high toughness, high temperature plastics research and development capabilities; improve the overall level of enterprise information management and integrated manufacturing mold.

China's mold industry will be the high road by car dies

China's mold is the only way for enterprises to develop high-end line of automotive die.
According to statistics, last year China's key enterprises reached nearly 110 die, which accounts for about 37% of stamping dies, these data demonstrated a strong automotive mold manufacturing country, China has become a fact. However, the development of China's automotive die but not so ideal, high-end automotive mold enterprise technology is not up to the level of technological innovation capability, inadequate new mold R & D capabilities, etc. The reason for this series are restricting the development  tapping tee electrofusion mould of China's automobile mold industry leading automobile companies can not produce molds and dies to match the high-end market, high-end car manufacturers need to mold must also rely on imports. The domestic high-end enterprise occasionally die because of lack of production load, had to change the initial market positioning away seize, the low-end market. Although the survival of the enterprise to solve the problem, but because of the low-end market, low profit margins, leading to invest R & D and technological innovation rarely, under certain circumstances, a vicious cycle in which companies did not enter a virtuous cycle of development , the domestic mold companies are more high-end cars, making it faces increasingly fierce competition in the market. In addition to the domestic high-end automotive mold companies to meet the traditional mold enterprise Q (quality), C (cost), T (period) requirements, mold development and electrofusion coupling mould  application of new technologies will become the focus of the future direction of domestic mold industry development. Multi-position progressive die and precision die represents the development direction of stamping dies, precision and demanding life, mainly for the electronic information industry, automotive, instrumentation, electrical appliances and other facilities. Both mold, the country has fairly basic, and has the introduction of foreign technology and equipment, the products of individual enterprises has reached the world level, but most companies are still a large gap, the total is also in short supply, import more.
For ultra large scale integrated circuit  Bridge Bend mould package for more than 100 and a lead foot gap 0.2mm below the lead frame package for the accuracy of 5mm or more matching precision miniature connector for 1.6mm below the core support and micro-motors for the CRT electron gun and supporting the development of precision molds is a top priority.

Our mold companies can enhance the prospects of future innovation

Mold has "the mother of industry," said the foundation technology and equipment belonging to the industrial production. Today, the development of China's mold industry has formed a unique mold industry cluster production base for mold companies provide a platform for scientific development. Meanwhile, the innovation capacity of enterprises is also rising, with a number of independent intellectual property rights, the future of China's mold companies will have a stronger competitive.
Nearly a decade, China's automobile industry has made considerable progress. At present, China's mold industry output value  Bridge Bend mould of over $ 100 billion industry, one of the main application as a mold downstream automotive industry, China is about 1/3 of the mold products for the automotive service industry.
China mold industry after decades of accumulated technology and in recent years to increase international exchanges, pay close attention to technological innovation in production technology have achieved significant breakthroughs in business with more competitive, the industry expects 2015 sales value of China's mold will reach 350 billion yuan. Although in recent years the domestic mold exports increasing level of international competitiveness has improved. But mostly concentrated on middle and low areas, low mold technical level, low value-added, high-precision molds also part dependent on imports, so the domestic mold industry in various fields to strengthen integration.
Throughout the development process, related industries and businesses need long-term perspective, the potential lower mind, pay close attention to new technologies, new technology research side, and gradually form a division of labor, there is collaboration in all areas of research and development pattern, introduced with proprietary mold products. Now China's mold industry through the introduction of foreign capital, absorb the advanced experience of foreign mold manufacturing, advanced technology and high-level talents, our mold design and manufacturing level has been greatly improved.
"With the increasing domestic demand in China can be expected to die by 2013 China will have a larger growth industry, especially the automotive industry, has led to the rapid development of tapping tee electrofusion mould  China's mold industry, promote the rapid transformation and upgrading of mold enterprise." Luo Baihui mold experts believe, strengthen independent innovation in the industry change the growth mode, optimize the industrial structure, have a greater need high levels of mold machinery and equipment, providing a broad development space for the development of mold industry. More importantly, "five" the implementation of development policies and emerging strategic industries, regional development planning and policy to revitalize the equipment manufacturing industry will die industries are providing new growth point. With manufacturing in developed countries have to transfer to China, China's mold industry is facing a new round of development opportunities. Forecasts, and electrofusion coupling mould  the internal and external drives Qi moving environment, to 2015, China's mold will reach 350 billion yuan sales value. China's mold industry is currently experiencing competitive pressures are mainly price advantage and technological superiority of developed countries to developing countries, need to know not only the development and progress of industrial molds China, Southeast Asia and Eastern European countries in recent years, the development of industrial molds are very fast, its advantages in terms of mold price Obviously, this weakens the cost and price advantage of China's mold industry has always been a certain extent. In addition, Western Europe, Japan and South Korea on the strength of the high-end market, but also to mold China mold industry is facing enormous challenges.

Mould market demand is still the focus of technological development

Today, the mold industry, the rise of the technology boom , to further accelerate the reform of China's mold industry update path, and follow the mold industry restructuring led the entire industry into a new round of production dynasty , combined with high-tech mold production technology, enterprises can be more accurate, more efficient completion of  tapping tee electrofusion mould product design and production process , close to the international market pace .
China is a big country , but also a big consumer of industrial products , mold development as one of the essential modern industrial equipment, wide range of applications . At present , China's mold industry market is very large, and each year was 15% to 20 % trend growth , mainly  chinese mould due to the development of China's automobile , home appliances , IT industry , packaging , building materials, daily necessities , such as mold large user industry. Unfortunately, although the domestic market demand remains high demand for mold , but because of mold technology compared with the current international level there are still some gaps, resulting in mold manufacturing technology behind many of the independent development of the industry has been greatly restricted , some of the high-tech mold is still dependent on imports , coupled with advanced technology companies in recent years, more emphasis on the protection of the mold which caused some enterprises to introduce technical difficulties .
For this reason, and to improve the  PE Electrofusion Pipe Fitting level of China's mold industry Manufacturing became imperative thing. With the continuous development of the total economy and industrial products and technology, resulting in all walks of life for a growing demand for molds , technical requirements are also increasing focus on developing high-tech mold and constantly improve the level of standardization of the mold became the "second five" development priorities. Especially for tools need to rely on high-tech products as precision die mold industry , such as the computer's chassis , connectors , and many components in the manufacture of precision plastic mold and precision stamping dies , are electronic products can not be acquired equipment.

Auto Mould is an inevitable trend of high-end enterprise development

Last year , according to media statistics , China's mold of key enterprises reached nearly 110 , which accounts for about 37% of stamping dies , these data demonstrated a strong automotive mold manufacturing country , China has become a fact . However, the development of China's automotive die but not so ideal , high-end automotive mold enterprise technology is not up to the level of technological innovation capability , inadequate new mold R & D capabilities , etc. The reason for this series are restricting the development of China's automobile mold industry leading automobile companies can not produce molds and dies to match the high-end market , high-end car manufacturers need to mold must also rely on imports. The domestic high-end  Male/ Female Tee mould enterprise occasionally die because of lack of production load , had to change the initial market positioning away seize , the low-end market . Although the survival of the enterprise to solve the problem , but because of the low-end market, low profit margins , leading to invest R & D and technological innovation rarely , under certain circumstances, a vicious cycle in which companies did not enter a virtuous cycle of development , the domestic mold companies are more high-end cars , making it faces increasingly fierce competition in the market . Experts said that the domestic high-end automotive mold companies in addition to the traditional mold of enterprises to meet Q ( quality ), C ( cost ), T ( period ) requirements, mold development and application of new technologies will become the focus of future development of China 's mold industry direction .
Multi-position progressive die and precision die represents the development direction of stamping dies , precision  Bridge Bend mould and demanding life , mainly for the electronic information industry , automotive , instrumentation , electrical appliances and other facilities. Both mold , the country has fairly basic , and has the introduction of foreign technology and equipment, the products of individual enterprises has reached the world level, but most companies are still a large gap , the total is also in short supply , import more . For ultra large scale integrated circuit package for more than 100 and a lead foot gap 0.2mm below the lead frame package for the accuracy of 5mm or more matching precision miniature connector for 1.6mm below the core support and micro-motors for the CRT electron gun tapping tee electrofusion mould  and supporting the development of precision molds is a top priority .
Our high-end line of automotive die mold enterprise is the only way to development , market demand and also contributed to the development of other large and medium-sized stamping supporting multi-position progressive die should also focus on the development .

Temperature extrusion die selection and use principles

Warm extrusion molding technology at home and abroad in recent years, the rapid development of a non- cutting precision plastic forming process , and complete the crystallization temperature ( steel materials 200-850 ℃) temperature range between room temperature and heated . High -temperature extrusion parts strength , rigidity, light weight, accuracy and surface roughness almost in machining. Temperature extrusion die is to ensure the quality of the important temperature extrusion process equipment , selection and use of its principles are: 1 , mold material extrusion die temperature during  Male/ Female Tee mould the operating cycle , due to the high temperature , high pressure and alternating loads , requiring mold steel should have strength, high hardness , toughness , wear resistance and red hardness and good . Specifically:
1 ) low temperature (200-400 ℃) when pressed , the selection 3Cr3Mo3W2V, W18Cr4V, W6Mo5Cr4V2 so on. 2 ) medium temperature (400-500 ℃) extrusion , the choice 4Cr5MoSiV, 4Cr5W2SiV, 5CrNiMo so on. 3 ) high temperature (500 ℃ above ) extrusion , the choice 5Cr4Mo3SiMnVAl, 6Cr4Mo3Ni2WV, 3Cr3Mo3W2V, 9Cr6W3Mo2V2.2, mold structure in the mold structure design, mold structure should be considered as much as possible in favor of the metal flow , die each part of the force uniform, fully consider cross-sectional shape of the cavity , the working parts should be smooth connection , try to avoid sharp corners , the stress concentration caused by the source slit to prevent cracking heat treatment and extrusion process . 3, the surface 2 inch pvc coupling mould  toughening treatment should be reasonable toughening treatment and surface hardening, the mold to get a good overall toughness and high surface hardness, wear resistance and mucosal performance , improve die life . If , Cr4W2Mo2V warm extrusion die technology: heat deformation normalizing (960 ℃, insulation 1.5h) + ball isothermal annealing (900 ℃, insulation 5h) + temperature quenching (1000-1050 ℃, oil quenched ) + temperature back fire (560-580 ℃, 1.5h) + SCN triple penetration process for review toughening treatment . Again 3Cr2W8V extrusion die temperature : 1100 ℃ heat insulation baked with pre-cooling 2-3min, and then placed in 50% K2NO3 +50% Na2NO3 salt bath , 390 ℃ insulation 0.5h baked cooled to room temperature isothermal quenching 560 ℃ × 2h tempering twice. 4 , friction reduction and lubrication method in direct contact with the blank mold surface , the mold surface blank or brush tapping tee electrofusion mould  invasion lubricants to reduce friction , can also improve thermal conductivity. Before dipping rough and can reduce heating oxidation and decarbonization . Production found : Graphite + boron oxide , boron oxide + molybdenum disulfide , graphite, i.e., water or oil , graphite, molybdenum disulfide + + oleic acid + alumina + silica sand and lubricants , can achieve good lubrication.

Mould is expected to become the new darling of the home building industry

Mould in the home has a very important position , but the domestic high-end home hardware market and more profitable brands on the market are mostly imported metal mold enterprise occupation , major brands of furniture and cabinet hardware mold parts are imported five basic imported.
According to experts molds , furniture quality and grade is mainly reflected in the selection of hardware accessories . Furniture inconvenient to use , in large part because of the improper selection of furniture hardware accessories , or lack caused . As long as there is tapping tee electrofusion mould  a corresponding metal mold parts , can be very complex multi-functional furniture made ​​out . Mould accessories in the value of the furniture in the proportion of 5%, but accounted for 85% of running comfort , the importance of furniture hardware accessories in the visible . Home hardware settings can be divided according to two categories of general and special , the former including hinges , hinges, slides , etc. , the latter including bathroom and kitchen hardware accessories and so on. Which hinges, slides, hinges and locks most frequently used in life, and therefore all the more important. In recent years, due to the ever increasing consumer demand for hardware accessories made ​​greater demand and higher requirements. Home Hardware is more emphasis on its mechanical properties , rust , moisture , and other moving parts of the fatigue performance quality .
Increasing demand for personalized in home improvement and integrity today, home hardware in addition to satisfying the above functionality , but also has a decorative and decoration style matching with the overall integrity of bright spots . Take the most common handle electrofusion coupling mould  is currently on the market in addition to stainless steel salad hand , there are black, bronze , chrome, pearl nickel plus lacquer, in shape, Continental , and Chinese, and conventional , shaped , etc. , to meet the diverse needs of consumers . As the role of furniture hardware on furniture and decor are no longer just part of the activities connected component , its functionality is growing, more and more widely involved in the field of furniture manufacturing enterprises to improve production efficiency , reduce costs, improve product quality, enhance the competitiveness of domestic and foreign markets , create efficiency have played a positive role. With the development of industrial technology , furniture, hand made ​​from the previous workshops, to today's mechanized production. Mould accessories for versatility, compatibility , functionality, decorative have higher requirements . Diversification of the substrate, increasing the structural reforms and the use of functions. With injection mould  the development of metal mold industry , I believe that in the near future , furniture and cabinets are no longer just used for mold parts imported from abroad , our own technology development will change the industry to bring more surprises.

Status and Development of rapid economic mold

The main problem areas of rapid economic mold problems are: rapid tooling our professional business is relatively small, the impact of China's own brand of new product development trial . Development of new models such as cars , most of them choose foreign OEMs new models fast trial enterprises, or foreign country , mainly because of domestic enterprises with less rapid economic mold or development is not strong enough , the impact of the automobile OEMs selection. Second, China's rapid tooling  Male/ Female Tee mould companies , mostly small and medium enterprises , self-development capacity is weak, although technically close to the international advanced level , but is limited in terms of investment in technological innovation capability .
The gap with the international advanced level in recent years , China's rapid economic mold technology has developed rapidly, especially the popularity of CNC machining equipment , mold design and quality has been greatly improved , can substitute imports. But compared with  Plastic Adapter Union mould foreign advanced level of rapid tooling technology , there are still some gaps .
Automotive panel die quickly after years of technical accumulation , as well as new technologies, new materials, grafting, its manufacturing level and speed has been significantly improved . Compared with the international advanced level the gap is mainly reflected in : the international advanced automotive panel die manufacturing enterprise is a fast rapid tooling technology, auto body technology in a new product for automotive OEMs to develop, implement from rapid tooling , stamping welding train service. Domestic automobile cover rapid tooling manufacturing enterprises. Only assume rapid tooling manufacturing and stamping, die quickly lead to domestic enterprises lack of live sources , to improve the overall level slower . Plus car cover rapid mold manufacturing enterprises , mostly SMEs , investment capacity is weak, the introduction of advanced high-speed processing equipment and line testing equipment for less , it can not ensure the rapid development of high-end products.
Since the emergence of rapid prototyping technology , after 20 years of development , RP technology has entered a mature stage of steady development , there have been dozens of different apping tee electrofusion mould  processes. Our rapid prototyping technology is not bad . Compared with the international advanced level , the main difference lies in product research and commercialization conversion is slow, as China's current rapid prototyping rapid tooling technology conversion means for large stamping dies quickly oversized rapid prototyping techniques and equipment has not yet appeared . I plant a cement mold, cover mold and other products undergo strict quality certification system , trustworthy.

Proper use and maintenance of die mold for extending the life of tile has a decisive significance. Mounting the die presses must have sufficient rigidity, strength and precision. Depth die after installation, when adjusting the blanking die punch into the die can not be too dark.

Keep up the pace of plastic mold market prospects

In recent years, with the rapid development of electronic information industry and information technology transformation , the prospect of a vast plastic mold market , the world's high-grade , precision plastic mold market is in short supply situation of traditional industries.
The weight of a single set of plastic mold manufacturing level has been greatly improved, the production of  Coupler mould large plastic mold has reached more than 50t , the accuracy of precision plastic mold has reached 3cm, multi-cavity plastic molds capable of producing plastic mold cavity of a mold 7800 , high-speed extrusion molds capable of producing more than the speed of high-speed 4m/min plastic profile extrusion dies and coextrusion die lumen main sections . With the continuous improvement of the rapid development of the plastics industry and general engineering plastics in terms of intensity , scope of application of plastic products is also expanding , the amount of plastic products is on the rise . It is understood that China 's output of plastic products in 2012 nearly 60 million tons , and continues to  tapping tee electrofusion mould grow process, we can see that domestic demand for China's plastic mold industry has a huge impetus.
In recent years, according to the International Association of mold , the mold industry associations to actively encourage member companies to update technology and equipment , to promote the technology and product innovation , and guide qualified enterprises from production processes to develop , expand sales of high value-added mold , injection mold manufacturing have a new large-scale expansion. Regional and national distribution of plastic processing industry is similar to the Pearl River Delta , Yangtze River  Delta plastics processing industry forefront , Zhejiang, Jiangsu and Guangdong, the  Shorter Pipe Clip proportion of the national output of plastic mold mold output value also accounted for 70 %. With the Chinese automotive, appliance, electronic communications , the rapid development of various building materials, is expected to die in the future market, accounting for the total amount of plastic mold will gradually increase the proportion of mold , and the growth rate will be faster than other mold.

Advantages of high-speed cutting technology for the processing of the mold

Gold mode network CEO,  mold technology expert committee believes that local contemporary high-speed cutting is not improved cutting speed is needed in the manufacture of technical progress and comprehensive basis for further innovation, including CNC machine tools, tool materials, coatings, Significant advances in technologies such as tool structure, in order to achieve the cutting speed and feed speed is doubled, the manufacturing sector as a whole in order to make cutting efficiency improved significantly. The current level of practical high-speed cutting, the overall improved cutting efficiency machining of 1 to 2 times, narrowing the gap with industrialized countries, China is engaged in cutting tool technology professionals with the efforts and goals of the new century, facing major challenge.
Its mold industry in recent years, undergoing a massive technological revolution, which is gradually replaced by high-speed processing equipment cutting tools, precision mold cavity for efficient processing. These tools include a variety of high-speed CNC milling machines, machining centers. Currently in mold manufacturing process, mainly in general machining and EDM processing. General machining of the mold cavity prior to heat treatment are generally roughing, semi-finishing and finishing, and grinding, polishing, time-consuming and laborious. EDM is performed after annealing, machining and heat treatment, EDM, grinding after final polishing.
The disadvantage with the accelerated replacement rate of consumer products, the production efficiency and manufacturing quality molds made increasing demands productivity EDM die poor and unstable quality gradually exposed. Luo Hui said mold companies to shorten the manufacturing cycle and reduce costs, we must extensive use of advanced machining technology, and the emergence of advanced manufacturing technology on behalf of high-speed cutting technology to meet the demands of modern tooling and features.
Technical advantages for high-speed cutting machining molds mainly reflected in:
(1) greatly improves the processing efficiency, not  PE Electrofusion Pipe Fitting only high machine speed, feed fast, and rough finishing can be completed, greatly improving the efficiency of production, combined with CNC technology, mold manufacturing cycle can be shortened by about 40%.
(2) high-speed machining molds do not require electrodes do not need subsequent grinding and polishing process automation is also easy to implement and improve the speed of development of the mold.
(3) the use of high-speed cutting technology processed hardened steel, and get a high surface quality, surface roughness less than Ra0.6m, made with milling and grinding processing effect, not only saves a lot of time, but also improves the machined surface quality.
