In order to meet the mold products "short delivery time", "high precision", "good quality", "low price" requirements of service. With the rapid development and organic combination of computer technology, mechanical design and manufacturing technology, the new technology of computer aided design and computer aided manufacturing (CAD / CAM) has been formed.

CAD / CAM is the key technology to transform the traditional mold production mode. It is a high-tech and high-efficiency system engineering. It provides users with an effective auxiliary tool in the form of computer software, so that engineering and technical personnel can design and optimize products, mold structure, forming process, numerical control processing and cost with the help of computer. Die CAD / CAM can significantly shorten the die design and manufacturing cycle, reduce production costs and improve product quality.

With the emergence of powerful professional software and efficient integrated manufacturing equipment, mold CAD / CAM technology based on 3D modeling and concurrent engineering (CE) is becoming the development direction, It can realize the design for manufacturing and assembly, realize the simulation of forming process and NC machining process, and integrate design and manufacturing.

In order to meet the needs of multi variety and small batch production in industrial production, the development and application of rapid economic mold making technology has been paid more and more attention. The rapid economic mold making technology mainly includes low melting point alloy mold making technology, zinc based alloy mold making technology, epoxy resin mold making technology, spray forming mold making technology, laminated steel plate mold making technology, etc. The rapid economic mold making technology can simplify the mold manufacturing process, shorten the manufacturing cycle (70% ～ 90% shorter than the ordinary steel mold manufacturing cycle) and reduce the mold production cost (60% ～ 80% lower than the ordinary steel mold manufacturing cost), which has achieved remarkable economic benefits in industrial production. It plays a very important role in improving the development speed of new products and promoting the development of production.
