[0002] Low-pressure injection molding is an injection molding process that uses very small injection pressure to inject the injection material into the mold and quickly solidify it to achieve insulation, temperature resistance, impact resistance, and corrosion resistance.

[0003] In the normal pressure back injection molding process of pre-cut soft small fabrics, the injection mold needs to fix the surface fabric in the injection mold cavity by hanging pins. When the hanging pins are fixed, threads are usually set at their rear ends to rotate them into the template.
