Injection mold is an important process equipment for producing various industrial products. With the rapid development of plastic industry and the popularization and application of plastic products in aviation, aerospace, electronics, machinery, shipbuilding, automobile and other industrial departments, the requirements of products for molds are becoming higher and higher. The traditional mold design methods can not meet the requirements of today Compared with traditional mold design, computer aided engineering (CAE) technology has great advantages in improving productivity, ensuring product quality, reducing cost and reducing labor intensity.

In the processing of injection mold, all kinds of NC processing are useful. The most widely used are NC milling and machining centers. NC wire cutting and NC EDM are also widely used in mold NC processing. Wire cutting is mainly used in the processing of various straight wall molds, such as concave convex die in stamping, insert block and slider in injection mold, Electrodes for EDM, etc. For mold parts with high hardness, machining methods cannot be used, and EDM is mostly used. In addition, EDM is also used for sharp corners, deep cavities and narrow grooves of mold cavity. CNC lathes are mainly used to process standard parts such as mold rods, mold cavities or cores of rotating bodies, such as injection molds for bottle bodies and pots, and forging molds for shaft and disc parts. In mold processing, the application of NC drilling machine can also improve the machining accuracy and shorten the machining cycle.

Molds are widely used. Almost all the forming and processing of product components in modern manufacturing industry need to be completed by molds. Therefore, the mold industry is an important part of the national high-tech industry and an important and valuable technical resource. Optimize the structural design of die system and CAD / CAE / CAM of parts, and make it intelligent, improve the forming and processing technology of parts and the standardization level of dies, improve the precision and quality of die manufacturing, and reduce the amount of grinding and polishing operations and manufacturing cycle of parts; Research and apply the special materials with high performance and easy cutting used for various types of mold parts to improve the service performance of the mold; In order to adapt to market diversification and trial production of new products, the application of rapid prototype manufacturing technology and rapid mold making technology to rapidly manufacture forming dies, plastic injection molds or die-casting molds should be the development trend of mold production technology in the next 5 ~ 20 years.
