High-precision auto - - precision

High-precision auto - - Precision precision automotive stamping parts, as the name suggests, is what car parts made of metal stamping parts. In automotive stamping parts, the part after stamping become auto parts directly, the other part after stamping the need after welding, mechanical processing, or paint process before they can become auto parts, etc. Is a great variety of automotive stamping parts, such as automobile shock absorber spring pressing tray, spring seat, spring bracket, end cover, seal, zip compression valve cover, valve cover, oil seal, bottom cover, dust cover, impeller, oil cylinder, the ears, such as stents are automotive stamping parts. High-precision car selection principles in selecting materials, first of all, depending on the type of automobile stamping and use characteristics, to choose to have different mechanical properties of metal materials, in order to achieve both can guarantee product quality, and can save material. Usually when choosing auto stamping materials should follow the following principles: a selected material first auto parts to meet the performance requirements; B the selected material has good process performance; C the selected material should have a good economy. High-precision car selection in the production of automotive stamping parts using a large amount of cold stamping process for automobile stamping industry many varieties, the needs of the mass production. In the medium and heavy duty truck, most of the covering parts such as body outer panel, and some bearing and supporting parts such as chassis, car and other auto parts are automotive stamping parts. Used in cold stamping steel plate and steel belt is the main steel, 72 of the vehicle steel consumption. 6%, and cold stamping materials close relation with auto stamping parts production, the stand or fall of material not only decides the performance of the product, more directly affect the process design of automobile stamping process, affect the product quality, cost, service life and production organization, thus a reasonable choice material is an important and complex work.
