Metal stamping parts are made of stainless steel, iron, aluminum, copper and other plates and heterosexual materials by using punch and die at room temperature to deform or fracture, so as to form the desired shape products. Its processing technology includes blanking, bending, deep drawing, forming, finishing and other processes.
Metal stamping is originally metal or non-metal sheet material, with the help of press pressure, through the stamping die stamping forming process, in the premise of material loss, metal stamping production process, after punching out.
Metal Stamping China processing advantages:
1, metal stamping by the mold to ensure the size and shape accuracy, generally does not destroy the surface quality, and the life of the mold is generally long so the metal stamping quality is stable.
2, can be processed with a large size range, more complex shape parts, such as small to the stopwatch of a clock, large to the car longitudinal beam, covering parts, etc., coupled with the cold deformation hardening effect of the stamping material, the strength and stiffness are high.
3, high production efficiency and convenient operation, easy to realize mechanism and automation.
4, metal stamping generally does not generate cuttings, material consumption is less, and does not need other heating equipment, so it is a kind of material saving, energy saving processing method, low cost.
Commonly used hardware stamping parts processing products, surface treatment generally has the following:
1. Electroplating treatment: the parts receiving electroplating are immersed in the aqueous solution containing the deposited metal compounds, and the current is passed through the plating solution to make the electroplated metal precipitate and deposit on the parts. Its role is to ensure that the workpiece for a long time under the use of mildew rust, corrosion resistance.
2, anodic oxidation: metal or alloy parts as an anode, using the method of electrolysis to form oxide film on its surface. This film improves the surface condition and properties of the workpiece.
3, polishing processing: the use of flexible polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. Make the stamping surface smooth and smooth, no burr, reduce the surface roughness.
4. Surface quenching: refers to the heat treatment process of rapidly heating the surface of the stamping parts to the quenching temperature within a certain depth range, and then rapidly cooling, to achieve the purpose of quenching to a certain extent, so as to improve the surface hardness to meet the performance of wear resistance and impact resistance.
