Car charger shell mould
There are many steels for auto parts injection molds, but auto parts injection molds also have a lot of questions about the choice of steel. Different surface technology of auto parts choose different injection mold steel.
First of all, the steel for injection molds for auto parts can be roughly divided into two categories, one is imported steel, and the other is domestic steel. Generally, imported steel is used for export molds, or customers have higher requirements for molds. The cost of imported steel is relatively expensive, which is 3 to 4 times that of domestic steel. For auto parts, high-gloss mirror technology can be given priority. S136 steel, this steel can achieve a mirror effect. If the surface of the auto parts is textured, you can choose NAK80 steel. NAK80 is in a pre-hardened state, no heat treatment is required, and the production life can reach over 500,000 deformations.
Auto parts injection molds are very demanding in the selection of steel, and the material is directly related to the quality and life of the mold. To make the auto parts injection mold well, the steel must be selected to make a quality auto parts injection mold.
