The sheet metal processing production process refers to the entire process of making products from raw materials (or semi-finished products). For machine production, it includes the transportation and storage of…
1. Features: It depends on whether the chassis provides front USB and audio input and output ports. For example, the internal design of the hard disk, optical drive adopts rail…
Metal Stamping parts are processed in a variety of steel plate specifications, whether it is coiled or fixed-length version, the same material, material thickness, and different coil widths, the sales…
(1) Defects such as high yield point, high hardness, significant cold hardening effect, and cracks. (2) The thermal conductivity is worse than that of ordinary carbon steel, which results in…
1. The material used for blanking should have sufficient plasticity and low hardness to improve the quality of the blanking section and dimensional accuracy. Among them, soft materials (such as…
