The injection moulding process mainly consists of 6 stages: mold closing – filling – holding pressure – cooling – mold opening –Demolding, and other 6 stages. These 6 stages directly determine the moulding quality of the product, and these six stages are a complete nonstop process. also we concentrate on the 4 stages filling, holding […]

Thermosetting plastics are phenolic, amino (melamine, urea-formaldehyde), polyester, polypropylene phthalate, etc. Mainly used for compression moulding, extrusion, and injection moulding. Silicone, epoxy resin and other plastics are used mainly as low-pressure extrusion packaging electronic components and casting moulding.   1.

Thermoset injection molding uses a screw or a plunger to pass the polymer through a heated barrel (120-260°F) to reduce density and fit it into the heated earth (300-450 °F). Once the material fills the world, it’s held under pressure.  At this point, chemical cross-linking occurs, causing the polymer to harden. The complex (i.e., cured)
