Injection mold is an important process equipment for the production of various industrial products. With the rapid development of the plastic industry and the promotion and application of plastic products in aviation, aerospace, electronics, machinery, ships and automobiles and other industrial sectors, the requirements of products on molds are also increasing. The higher the age, the more traditional mold design methods have been unable to adapt to today's requirements.

Compared with traditional mold design, computer-aided engineering technology has great advantages in improving productivity, ensuring product quality, reducing costs and reducing labor intensity.

In the processing of injection molds, all kinds of CNC machining are used. The most widely used are CNC milling and machining centers. The application of CNC wire cutting and CNC EDM in the CNC machining of molds is also very common. Wire cutting is mainly used in various The straight-walled mold processing is also used for the sharp corners, deep cavity parts, and narrow grooves of the mold cavity.
