Plastic molding products processed by injection moulds may need to be made into two parts and then joined together in a suitable way if they have concave shapes, etc. The joint processing methods of injection mold molding products mainly include hot melt method, instant hot melt method, hot air weld

Thread molding product injection mold processing is still very difficult, the main reason is because there is a concave thread product can not be normally demoulded, this kind of thread products including bottle caps, containers, mechanical parts, etc., the application range is still very wide. The

The ultimate purpose of quenching of injection mold core and parts is to increase its hardness and corrosion resistance. It is also important to pay attention to what situation the injection mold needs to be quenched. Not all molds need to be quenched, and the problem of uneven quenching caused by m

The principle of this defect in injection mold is that the air in the cavity is compressed in the sealed space and heats and burns itself, resulting in the scorching of injection molding products. Specifically, the air compression will generate heat, and the residual air compression in the cavity is
