The numerical control machining of the blowing mold has a certain typicality and has higher requirements than the numerical control processing of ordinary products. In the processing of molds, various CNC machining are used. The most widely used CNC milling and machining centers. The application of CNC wire cutting and CNC EDM in CNC machining is also very common. Wire cutting is mainly used in various Straight wall mold processing, such as concave and convex molds in press processing, inserts, sliders in blow molds, electrodes for electrical discharge machining, and the like.

For mold parts with high hardness, machining methods can not be used, most of them use EDM, and EDM is also used for sharp corners, deep cavity parts and narrow grooves of mold cavities.

The CNC lathe is mainly used for processing standard parts of mold rods, as well as mold cavities or cores of rotary bodies, such as blow molds for bottles and basins, and forgings for shafts and disc parts. In the mold processing, the application of the CNC drilling machine can also play a role in improving the machining accuracy and shortening the machining cycle.

Automatic blow moulding is an important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application of plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the products are moulded. The requirements are getting higher and higher, and the traditional mold design methods have been unable to meet the requirements of today.

Compared with traditional mold design, computer-aided engineering (CAE) technology has great advantages in terms of improving productivity, ensuring product quality, reducing cost and reducing labor intensity.
