. The underdevelopment of the mold industry will seriously affect the production of manufacturing products such as automobiles, IT and electronic technology products, mechanical and electrical products, aviation (sky), ships, building materials, and household appliances.

Moulds are special forming tools and special tooling for forming manufacturing product parts (including stamping parts, plastic parts, forgings, rubber parts, glass and ceramic parts, etc.), as well as special technical products.

The mold will be specially designed and manufactured according to the technical requirements and production batches of the shape, size and dimensional accuracy, surface quality of the manufacturing product parts.

Therefore, study the modern design and manufacturing technology of molds, study the practical experience in the mold design and manufacturing process, and the technical management and process control of the production process, and form a standard, form an expert system, which is helpful to improve the mold production technology and management level, Improving the core competitiveness of mold companies will be of utmost importance.
Modern mold production method and production process
Before the 1930s, simple tools and equipment were used to form a workshop-style production method of hand-made molds. During this period, only simple molds can be manufactured. The manufacturing accuracy and quality of molds are completely dependent on manual skills and practical experience.
From the 1930s to the late 1970s, it was the development process of industrialized production methods for molds. Its main achievements and characteristics are:
Widely use milling process, precision forming and grinding process, and realize round hole and shape with precise pitch
EDM processing technology and NC wire EDM processing technology are widely used, providing key processing technology for high-hard materials.
Realize the specialization, serialization and standardization of mold materials.
In the meantime, the high development of mold standardization, the comprehensive use of standard parts and components for design and manufacturing in mold production, is not only a major achievement and feature of the industrialized production method of molds, but also an important technical basis for realizing modern mold production methods.

With the progress and development of the computer and machine tool industry, since 1980, mold CAD/CAM and CAD/CAM/CAE have become widely used production technologies. They cooperate with the high degree of standardization to form a modern mold production method, that is, an informatized and digital mold production method that realizes mold design and manufacturing.
