China's stamping die industry presents nine development trends
Mold is the basic process equipment of the automobile industry. More than 90% of the parts in the automobile production need to be formed by the die. According to reports, the manufacture of an ordinary car about 1500 sets of molds, of which stamping die about 1000 sets. In the development of the new car model, 90% of the workload is around the body surface changes. About 60% of new vehicle development costs are for car body and stamping processes and equipment development. About 40% of the cost of car manufacturing is the cost of car body stamping and assembly.
In the development of automobile mould industry both at home and abroad, mold technology shows the following nine development trends.
1, mold three-dimensional design position can be consolidated
The three-dimensional design of mold is an important content of digital die technology, and is the basis for realizing the integration of mould design, manufacture and inspection.
2, the stamping process simulation (CAE) role is more prominent
In recent years, with the rapid development of computer software and hardware, the simulation technology of stamping forming process (CAE) is playing an increasingly important role.
3 digital mold technology has become the mainstream direction
In recent years, the rapid development of digital mold technology is an effective way to solve many problems faced in the development of automotive mold.
4, the rapid development of mold processing automation
Advanced processing technology and equipment are the important basis for improving productivity and ensuring product quality.
5, high strength steel stamping technology is the future direction of development
Because of its excellent characteristics such as yield strength ratio, strain hardening property, strain distribution ability and impact energy absorption, high strength steel has been used more and more in automobiles.
6, the new mold products timely launch
With the development of high efficiency and automation of automobile stamping production, progressive die will be widely used in the production of automobile stamping parts.
7, die materials and surface treatment technology will be reused
The quality and performance of mold materials are important factors affecting the quality, life and cost of the die.
8, the management of scientific and information technology is the development direction of mold enterprises
Another important aspect of the development of automotive mould technology is the scientific management and informatization.
9, the refinement of the mold manufacturing is an inevitable trend
The so-called fine mould manufacturing is concerned, the development process and results of the mold manufacturing, the specific performance for stamping process and die structure design is reasonable, high precision mold processing, mold products of high reliability and strict technical management.
