Stamping parts processing in our side, we have been used to it, but sometimes if we meet bad merchants, the quality of our stamping parts may not be so good, so how to ensure the quality of stamping processing?
In daily life, metal stamping products are everywhere. How to improve customer production efficiency and quality assurance is the core direction of Rongxiang Company. To assist customers to enhance competitiveness as their own duty, equipment and technology are indispensable.
The following aspects of metal stamping parts are indispensable.
- Chemical analysis and metallographic inspection.Analyze the content of chemical elements in the material, determine the grain size grade and uniformity degree of the material, evaluate the grade of free cementite, banded structure and nonmetallic inclusions in the material, and check the defects of the material such as shrinkage hole and porosity.
- material inspection.The materials processed by stamping parts are mainly hot rolled or cold rolled metal plate and strip materials. The raw materials of metal stamping parts should have a quality certificate, which guarantees that the materials meet the specified technical requirements. When there is no quality certificate or for other reasons, the metal stamping parts manufacturer can choose raw materials for reinspection as required.
- Formability test.The bending test and cup test of the material are carried out to determine the work hardening index n value and plastic strain ratio r value of the material. In addition, the test method of steel sheet formability can be carried out according to the regulation of steel sheet formability and test method.
- Hardness testing.The hardness of metal stamping parts is tested by Rockwell hardness tester. A small, complex shape of a stamped part that can be tested on a surface too small to be tested on a common bench Rockwell hardness tester.
- Determination of other performance requirements.Determination of electromagnetic properties of materials and adhesion to coatings and coatings, etc.
Stamping parts processing is a kind of metal processing method that we have arisen in recent years. Stamping parts processing products are everywhere in our life, but do you understand the principle of stamping parts processing?
In life, hardware has been used in many places. With the development of society, the application of hardware is more and more. Such as lighters, zippers, wrenches, pliers, etc., have a good sales record in foreign countries. At the same time, after many years of development, the characteristics of the development of hardware industry cluster are gradually highlighted.
- Stamping parts are produced by stamping under the premise of little material consumption. The parts are light in weight and good in stiffness.
- The stamping parts have high dimensional accuracy, uniform size with the module, and good interchangeability. General assembly and use requirements can be met without further machining.
- In the stamping process, because the surface of the material is not damaged, it has good surface quality, smooth and beautiful appearance, which provides convenient conditions for the surface spray painting, electroplating, phosphating and other surface treatment.
