With the rapid development of science and technology, the advancement of the era of mold manufacturing and processing technology is constantly updated, the birth of new technology has eliminated the old technology, especially the transformation from semi-automated production to high-precision mechanized production. Looking back at the development of China's mold industry, there have been general developments in the past 10 years. Faced with a huge international market, companies in China's mold industry are stepping up their introduction of technology and innovating new technologies to counter future risks. The advantage of China's bottom cost is no longer there.
The most used plastic mold processing technology is 1. EDM milling and "green" product technology. 2, high-speed milling: the third generation of molding technology. 3. A new generation of mold CAD/CAM software technology. 4. Advanced rapid mold manufacturing technology. 5, mirror polished mold surface engineering technology. 6. On-site mold inspection technology.
Generally speaking, the produced mold is processed by traditional machining. Since the mold has some complicated features and free surfaces, the precision and the finish are relatively high, the processing cycle is long, and the cost is high.
Mold processing, due to the development of computer numerical control (CNC) processing machine tools, machining centers, flexible systems, and high-speed cutting, can shorten the cycle of mold processing, but so far, there is no major change in the process of each process, still There are large problems such as long adjustment time, difficulty in automatically generating complicated tool paths, and high cost. When the production volume of the product is small, the amount of man-hours and cost of the mold is even greater on each product, and the above problems are more prominent.
Another problem with conventional machining molds is that the flexibility of such molds is relatively poor. Once the design changes, the original molds are difficult to modify and almost have to be reworked. Therefore, the production of the mold requires high-precision structural design and repeated testing. Once the modification needs to be made, the redesign of the entire mold is often a problem encountered by many companies. The cost of a complete mold is as high as tens of thousands so that the maintenance cost of the mold is quite expensive. Therefore, it is necessary to return to the test when the mold is designed.
