Selection of Mold Steel Materials
The appearance of steel patterns on molds usually has two main causes: One is the quality of steel material ,many mold manufacturers choose lower-quality steel to save costs, which can result in surface patterns and fine lines after the molds undergo polishing. Under light, these patterns can cause distortion, and polishing can only alleviate the visibility of these steel patterns. The other reason is the polishing technician lacks adequate skills, it may also lead to the development of steel patterns on the mold surface.
