    Take a simple way to understand the injection molding process.

    What is Injection Molding: The injection molding process is a process of making semi-finished parts of a certain shape from molten raw materials through operations such as pressurization, injection, cooling, mold opening, and mold release. Its raw materials are ABS\PE polyethylene, PP polypropyl...
