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.

Metal cutting tools market-driven mold industry development

The rapid development of technology makes many industries increasingly frequent replacement rate , the tool market can not avoid this situation , and now, a simple single-function tool is gradually being replaced by multi-purpose tool . In the future , user research and development tools are constantly demanding more , not just material and surface coating technology limited tool , but the tool production technology will have a more stringent requirements.
In terms of technology updates , gradually replacing the high-speed steel cutting tools carbide cutting tools , especially plastic injection mould  circular tool .

Domestic market demand for high-grade mold large, according to forecasts, "Twelve Five" period, the total market steady upward trend in the mold , but the mold must meet the requirements of the domestic needs of users in terms of quality , delivery and so on. Moreover , appliance, automotive , plastics industry, the greatest demand for molds. International market in recent years, an increase in labor costs in industrial countries , the developing countries, especially Southeast Asian countries forward  plastic coupler fittings mould transfer . Its domestic production of high precision molds based, manual labor into large molds to rely on imports.
Therefore , middle and low mold international market potential is huge. As long as the quality of domestic mold can be improved , to ensure delivery , the export prospects of the mold is very optimistic. In addition , the demand in the international market is also a great standard mold . At present, only a small amount of exports . In the new wave of integration in the world economy, global manufacturing to accelerate the transfer to mainland China has become a trend , China will gradually develop into a world-class manufacturing base. Obvious advantages of Guangdong Pearl River Delta region in particular , will become the world's manufacturing center die  chinese mould within a decade .
Although China is the largest producer of molds , but many still rely on imports mold products to large, sophisticated, complex , long-life molds the majority, of the total imports in recent years has reached $ 1 billion . From the perspective of reducing imports , hardware tools market should continue to increase the proportion of high-grade mold , expanding domestic demand .

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.

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.

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.

China Mould market is expected to develop a large flow of commerce shall be bullish pattern

A wide assortment of hardware products, China has gradually become the world's largest metal processing and exporting countries, and has become one of the world's largest producer of metal, has a vast potential market and the consumer. International Mould & Metal & Plastic Industry Suppliers Association mold market is an important part of China's hardware chinese mould  industry, the five-time major changes are properly deal with our domestic and international environment for development, accelerate critical period to achieve the target of building a moderately prosperous society, but also China mold manufacturing the healthy development of the critical period, although many uncertainties in domestic and international environment, but China's economic development is still in the period of rapid growth, China's comparative advantage in the international mold mold market still exists, the domestic market is also expected to continue to be optimistic mold, mold industry development shows the trend. As more and more multinational companies entering the plastic coupler fittings mould  country, our local hardware business advantage is being challenged. Luo Baihui that our hardware is stainless steel enterprises, especially growth companies must clearly, must seize the strategic opportunities for development, the establishment of reasonable development goals for themselves. Not upstream, there is only the road to extinction. In the end business is to maximize profits or to create value for customers or for the benefit of employees? These points are business goals, but it simply speaking, if we are there to choose only one of the most important target, the value is the highest pursuit of business objectives.
Precision molds will be higher. 10 years ago, precision, precision molds is generally 5 microns, has now reached 2 to 3 micron, 1 micron precision die soon will be listed. This requires super finishing. Mold industry will become increasingly large. This is due to the molding of parts increasingly large-scale and high production efficiency requirements and the development of a multi-cavity mold caused. Multifunctional composite mold mold industry will be further developed. In addition to the new multi-functional composite mold stamping parts, but also responsible for layers, tapping, riveting and assembly tasks such as locking, the performance requirements of steel are also increasing. The Chinese hardware companies how to move forward mold in the rain it? Improve the process of the socialist market economic system, that is, the process of rapid flow, the flow does not know, do not know how the socialist market economy, is to improve the economic operation of modern circulation speed, quality and an important factor in efficiency. Therefore, in order to ensure the continued prosperity of hardware manufacturing, accelerate the development of mold hardware industry, we must do the work of several aspects.
Modern service industry must improve metal mold industry, the development of big business, the formation of large circulation, open circulation pattern, establish an efficient distribution platform, completely change the current hardware distribution platform small, scattered, weak status; must improve industrial development every aspect of the process through the province hardware industry cluster, forming large clusters metal industry, extend the industrial chain, to form interlocking, complementary production patterns, and enhance the overall competitiveness of the hardware industry; must promote hardware production technological innovation and brand building enterprises; must accelerate trade integration and integration of domestic and international trade and industry, and promote the transformation of economic structure adjustment and economic growth mode; must be to develop new markets, expand consumption as the main line, make full use of e-commerce and network service platform to promote hardware large market system, modern logistics system hardware, hardware market monitoring system and hardware business credit system construction, metal industry modernization of circulation as soon as  PE Electrofusion Pipe Fitting possible; need to improve communication and cooperation within the industry, sharing resources, the province's hardware business should be clearly aware of a variety of complex issues arise in the development process, we must pool everyone's wisdom and strength, the use of collective resources, while avoiding disadvantages, strengthen cooperation and promote multi-directional communication outside the industry, and jointly promote prosperity, the formation of the overall effect of the industry, actively respond to trade barriers may arise internationally active challenges to deal with the international market. Die hardware business leaders in determining the direction of development of the enterprise, to seize the key leadership, a clear focus on the work of enterprises, do not waste energy on other insignificant little things, if one thing can not promote staff enthusiasm, but also does not produce profits for corporate development role in promoting short-term or long-term, then it is unnecessary and can be ignored.
