Selection of Mold Steel Materials

Science Classroom / By

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.

Prevention of Pitting

Science Classroom / By

The formation of pitting during polishing—Is it a material issue or a technique problem? If it’s a technique issue, can it be prevented? To solve this problem, we first need to understand how it occurs. There are three main reasons behind this issue. Let’s take a closer look!

Several Methods for Achieving Mirror Finishing

Science Classroom / By

Mirror finishing refers to the process where the surface of a workpiece is polished to the point where it can reflect images like a mirror. This level of finish signifies exceptional surface quality, providing products not only with a high “aesthetic value” but also reducing notch effects, thereby extending the fatigue life of the workpiece. It holds significant importance in many assembly and sealing structures.

Sintering mechanism
