What factors affect the stability of stamping molds and products

Because most domestic stamping mold manufacturing enterprises are small and medium-sized enterprises, and a suitable portion of these enterprises are still in the traditional workshop style production management stage, they often neglect the stability of molds, resulting in long mold development cycles and high production costs, which severely restrict the pace of enterprise development.

As is well known, the metal materials used in stamping molds involve many varieties, and the requirements and selection criteria for their materials are also different due to the different effects of various parts in the mold. Therefore, how to select mold materials reasonably has become one of the very important tasks in mold design.

When selecting mold materials, in addition to requiring the material to have high strength, high wear resistance, and appropriate toughness, it is also necessary to fully consider the characteristics and production requirements of the processed product material in order to achieve the stability requirements of mold forming.

In practical operation, mold designers tend to select mold materials based on personal experience, which often leads to unstable mold forming due to improper material selection of mold parts in stamping. It is worth noting that during the stamping process, each type of stamping sheet has its own chemical composition, mechanical function, and characteristic values closely related to stamping function. The instability of stamping material function, fluctuations in stamping material thickness, and changes in stamping material not only directly affect the accuracy and quality of stamping processing, but may also lead to damage to stamping molds.

In order to solve the problem of mold stability, it is necessary to strictly control from the following aspects:

1. In the process planning stage, by analyzing the product, potential defects that may occur during production can be predicted, and then a stable production process plan can be developed;

2. Implement standardization of production processes and production techniques;

3. Establish a database and continuously summarize and optimize it; Using CAE analysis software system, obtain the optimal solution plan.
