Characteristics of metal stamping processing

In hardware processing, the isolation layer treatment of stamped parts usually involves isolating the blank on the surface of the metal stamping part, especially in the process of metal stamping and stretching, so lubricants or isolation layer treatment should be used. The detailed processing steps are as follows.
In hardware processing plants, lubricants are required when processing stamped parts, which are essential during the deep drawing process. The use of lubricants in the stamping process is to reduce friction, improve the service life of the mold, reduce the thinning of dangerous parts in deep drawn parts, and improve the surface quality of metal stamping parts. Therefore, in the process of metal stamping, how is the blank of the stamped part treated with an isolation layer?
Usually, this isolation layer treatment is used for thinning and deep drawing processes of stamped parts. Lubricants are used in thinning and deep drawing to reduce friction and cool the mold. Dry friction should not be used. During the drawing process, in addition to using lubricants normally, some materials also require isolation layer treatment. For example, when drawing steel parts, copper plating and phosphating treatment are often carried out on the surface of the billet to form an isolation layer between the billet surface and the mold, which can store liquids and have self-lubricating properties during the drawing process; When drawing stainless steel, high-temperature alloy steel and other parts, the mold is tightly clamped and the strengthening strength is high, so it is necessary to use an isolation layer to treat the surface of the billet.
