The development of mold technology should be adapted to the requirements of plastic mold products with short delivery time, high precision, good quality and low price.

Full promotion of CAD/CAM/CAE technology: Plastic mold CAD/CAM/CAE technology is the development direction of plastic mold design and manufacture. With the development and advancement of microcomputer software, the conditions for popularizing CAD/CAM/CAE technology have been basically mature, and enterprises will increase the intensity of CAD/CAM technology training and technical services; further expand the application scope of CAE technology. The development of computers and networks is making it possible to promote CAD/CAM/CAE technologies across the region, across enterprises and across campuses, and to re-integrate technical resources to make virtual manufacturing possible.

High-speed milling: High-speed milling processing developed in recent years in foreign countries has greatly improved processing efficiency and achieved high surface finish. In addition, it can also process high hardness modules, and has the advantages of low temperature rise and small thermal deformation. The development of high-speed milling technology has injected new vitality into the manufacture of large-cavity plastic molds in the automotive and home appliance industries. It has now evolved toward greater agility, intelligence, and integration.

Plastic Mold Scanning and Digitization Systems: High-speed scanners and plastic mold scanning systems provide the functionality needed to scan a model or physical object to a desired model, dramatically reducing the manufacturing cycle of plastic molds. Some fast scanning systems can be quickly installed on existing CNC milling machines and machining centers to achieve fast data acquisition, automatic generation of various CNC system processing programs, CAD data in different formats, and reverse engineering for plastic mold manufacturing. . The plastic mold scanning system has been successfully applied in the automotive, motorcycle, home appliance and other industries.

EDM milling: EDM milling technology, also known as EDM machining technology, is a new technology that replaces the traditional machining of the cavity with a forming motor. It uses a simple tubular electrode rotating at high speed for 3D or 2D. Contour machining is like CNC milling, so there is no need to manufacture complex shaped electrodes, which is a major development in the field of EDM. This technology has been applied in the processing of plastic molds abroad. This technology is expected to be developed.

Improve the standardization degree of plastic molds: The standardization degree of plastic molds in China is constantly improving. It is estimated that the coverage rate of standard parts for plastic molds in China has reached 30%. Developed countries in foreign countries generally have about 80%.

High-quality materials and advanced surface treatment technology: It is very important to use high-quality steel materials and apply corresponding surface treatment technology to improve the life of plastic molds. Heat treatment and surface treatment of plastic molds are the key to fully exploit the performance of plastic mold steel materials. The development direction of plastic mold heat treatment is vacuum heat treatment. The development direction of plastic mold surface treatment is advanced technology such as vapor deposition of TiN, TiC, etc., plasma spraying and other technologies.

The automation and intelligence of plastic mold grinding and polishing: the quality of plastic mold surface has a great impact on the service life of plastic molds and the appearance quality of parts. Automated, intelligent grinding and polishing methods replace existing manual operations and are an important way to improve the surface quality of plastic molds.

The development of plastic mold automatic processing system: This is the goal of China's long-term development. The plastic mold automatic processing system should have a reasonable combination of multiple machine tools; equipped with accompanying positioning fixtures or positioning discs; complete machine tool and tool CNC library; complete CNC flexible synchronization system; quality monitoring and control system.
