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.
