Stamping Parts of the raw materials should have a quality certificate
Stamping Parts manufacturers no matter what industry, have a principle. Including a screw cap industry, a Stamping Parts processing industry is the need to pay attention to the subject, then what is the Stamping Parts of the processing process need to pay attention to the principle of it? The following five points to introduce you.
1 design of the Stamping Parts must meet the product use and technical performance, and can facilitate the assembly and repair. In the case of
2. Stamping Parts manufacturers design Stamping Parts, should be conducive to the use of existing equipment, process equipment and process to its processing, and is conducive to the extension of the die life.
(3) the design of the Stamping Parts must be simple shape, reasonable structure to help simplify the mold structure, simplify the number of processes, that is, at least, the most simple stamping process to complete the entire parts of the processing, reduce the use of other methods of processing, and is conducive to Stamping manipulation, to facilitate the organization to achieve mechanization and automated production, to improve labor productivity. In the case of
4. The design of the Stamping Parts must be conducive to improving the utilization of metal materials, reduce the variety and specifications of materials, as much as possible to reduce the consumption of materials. In the case of allowing the use of low-cost materials, as far as possible to make parts without waste and waste disposal.
(5) The design of the Stamping Parts should be conducive to the use of existing equipment, process equipment and process to its processing, and is conducive to the extension of the die life.
Our daily life, Stamping Parts manufacturer hardware Stamping Parts everywhere, in order to improve customer productivity and quality as the goal, the introduction of foreign advanced technology with the product, the quality of metal Stamping Parts reflected from those aspects? From the following points
1, chemical analysis, metallographic examination
The levels of chemical elements in the materials were determined, the order of the grain size and the degree of uniformity of the materials were determined. The levels of free cementite, banded and non-metallic inclusions in the materials were evaluated, and the defects such as shrinkage and loosening were investigated.
Stamping Parts stamping processing quality reflected from those aspects?
2, material inspection
Stamping Parts of the material is mainly hot-rolled or cold-rolled (mainly cold-rolled) of the metal plate material, metal Stamping Parts of the raw materials should have a quality certificate, which ensures that the material meets the required technical requirements. When there is no quality certificate or for other reasons, the metal Stamping Parts production plant may need to select the raw materials for re-inspection.
3, Stamping Parts manufacturer forming performance test
The bending test of the material, the test of hardening index n and the plastic strain ratio r value of the material, and the test method of the forming performance of the steel sheet can be carried out according to the forming performance of the steel sheet and the test method.
4, hardness testing
Hardware hardness testing using Rockwell hardness. Small, with a complex shape of the Stamping Parts, can be used to test the plane is very small, can not be detected in the ordinary desktop Rockwell hardness.
5, Stamping Parts manufacturers other performance requirements determination
The electromagnetic properties of the material and the coating, coating adhesion and other determination.
Stamping Parts manufacturers Stamping Parts on the technical requirements and we share here, and also note that the hot metal Stamping Parts of the accuracy and surface conditions lower than the cold metal Stamping Parts, but still better than castings, forgings, cutting Less.
