The mold industry is a basic industry in the manufacturing industry and the basis for the transformation of technological achievements. At the same time, it is an important field of high-tech industries. It is called the “magnetic industry” in t...
Exhaust of injection molds is a problem that cannot be ignored in mold design. Poor exhaust gas can cause numerous problems, such as: porosity, voids, charring, air bubbles, surface silver streaks, and obvious weld lines.There are several sources of ...
The injection molds consists of two parts: a movable mold and a fixed mold. The movable mold is mounted on the moving template of the injection molding machine, and the fixed mold is mounted on the fixed template of the injection molding machine. In ...
