Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars.his process is actually an injection moulding process performed twice and therefore has a much smaller margin of error. In the first step, the base color material is moulded into a basic shape, which contains spaces for the second shot.
Each injection mold design must have a gate, or an opening that allows the molten plastic to be injected into the cavity of the mold. Gate type, design and location can have effects on the part such as part packing, gate removal or vestige, cosmetic appearance of the part, and part dimensions & warping.
