Dents are caused by local internal shrinkage after the gate is sealed or due to insufficient injection. Depression or micro-depression on the surface of injection molded products is an old problem in the injection molding process. Dents are generally caused by the increase in the wall thickness of the plastic product, which causes a local […]

Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the mold parts, the smaller the wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material. The toughness of the mold mainly depends

Injection molding: also known as injection molding, its principle is to add granular or powdered raw materials into the hopper of the injection machine. The raw materials are heated and melted into a flowing state. Under the push of the screw or piston of the injection machine, they enter the mold cavity through the nozzle

Injection molded parts dents are caused by shrinkage depressions caused by the cooling and hardening of the plastic, and mainly appear in thick wall positions, ribs, housings, the back of nut inserts, etc. Equipment Insufficient material supply The screw or plunger is severely worn, and the melt leaks during injection and pressure holding, reducing the

why do some places need to do inserts?
