A plastic mold is a tool used to shape objects. This tool is composed of various parts. Different plastic molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. Let’s get to know some common sense of plastic molds with everyone.
The mold wall plays a real role in the use of the mold and directly affects the processing and production operations. First of all, if the mold wall thickness is too thick, it will increase the cost, extend the forming time, reduce the production efficiency, and the quality is difficult to control, and bubbles, shrinkage holes, dents, etc. are prone to appear. However, if the wall thickness is too small, the strength of the mold itself is poor, and the resistance of the material flowing in the mold is large, and the shape is more complicated, and the forming will be difficult. Furthermore, if the wall thickness of the plastic part is not uniform, it will shrink unevenly after the forming process, which will not only cause bubbles, dents, and deformation, but also have large internal stress. When making the mold, avoid sharp corners at the junction of the mold wall thickness and the thin wall, but excessively should be relaxed, and the thickness should be gradually reduced along the direction of plastic flow.
