The exporter of Shanghai Qingpu hardware stamping parts said that the materials and molds + raw materials use the national standard original factory

Shanghai Qingpu hardware stamping parts exporter talked about materials and molds. Xiaoshuo had the honor to discuss some knowledge and share with you. Stamping processing includes punching, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) sheet metal materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy Plate, aluminum and aluminum alloy plate, etc. 1. Hardness testing of stamping materials The main purpose of testing the hardness of stamping materials is to determine whether the degree of annealing of the purchased metal sheet is suitable for the subsequent processing of stamping parts. Different types of stamping parts processing techniques require plates of different hardness levels. . The aluminum alloy plate used for stamping parts can be tested with a Webster hardness tester. When the thickness of the material is greater than 13mm, it can be changed to a Barcol hardness tester. The pure aluminum plate or low hardness aluminum alloy plate should use the Barcol hardness tester. 2. Hardness testing of stamping die The main material of stamping die is die steel (including tool steel and high-speed steel), and sometimes hard alloy is used. Stamping die is usually required to have high hardness and wear resistance, heat treatment is essential. Dongguan Hardware Co., Ltd., 15 years of experience in stamping parts production, more than 20 mold Ru0026D and design engineers, 5000 square meters workshop, hundreds of precision processing production equipment, 3 million punching next-day production capacity, 20000+ sets of stamping die customized production experience, stamping The precision of the processed parts can reach 0.01mm, 16 strict quality inspections, and seven precision stamping core technology patents.
