Dongguan metal stamping factory, brief introduction of raw material testing is the prerequisite for qualified results

Dongguan Hardware Stamping Factory, communicating with you, testing the raw materials before stamping is the prerequisite to ensure that the products are qualified and the process is smooth. What material testing does the stamping factory do before production: Xiaoshuo will take you to understand: 1. Chemical analysis, metallographic inspection, analyze the content of chemical elements in the material, determine the level of grain size and uniformity of the material, and evaluate the material The level of free cementite, band-like structure and non-metallic inclusions, inspection of material shrinkage, porosity and other defects. 2. Material inspection The materials of 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 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 forming performance test method can be carried out in accordance with the thin steel forming performance and test method. 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 and focus on Dongguan hardware stamping factory, 20,000+ sets of customized mold production experience, daily production capacity of 3 million punches, stamping accuracy can reach ±0.01mm, 16 quality inspection layers are strictly for quality control. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose to rest assured!
