Metal stamping parts control the inspection of each batch of stamping raw materials for customers

Metal stamping parts, raw materials are the prerequisite for bad and qualified, stamping factories, based on the reasons for the customer's choice of raw materials, do a good job of analysis and testing, in order to provide customers with more qualified stamping parts. 1. Chemical analysis and metallographic inspection analyze the content of chemical elements in the material, determine the level and uniformity of the material's grain size, evaluate the level of free cementite, band structure and non-metallic inclusions in the material, and check the material shrinkage, Defects such as looseness. 2. Material inspection The materials of stamping parts are mainly hot-rolled or cold-rolled sheet metal materials. The raw materials of metal stamping parts should have a quality certificate, which ensures that the materials meet the specified technical requirements. When there is no quality certificate or due to other reasons, the metal stamping parts factory can select raw materials for re-inspection as needed. 3. Formability test Carry out bending test and cupping test on the material to determine the work hardening index and plastic strain ratio of the material. In addition, the steel formability test method can be carried out in accordance with the thin steel formability and test methods. 4. Hardness testing The hardness testing of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be tested with other testing instruments. Hardware, 15 years of ingenuity focused on metal stamping parts, 20000+ sets of mold customization processing and production experience, monthly 100+ sets of mold processing capacity, 3 million punching production capacity per day, product accuracy up to 0.01mm16, strict quality inspection and delivery. It can quickly solve your time-critical problems, solve your stamping accuracy problems, and solve your mass production quality problems.
