On the other hand, these processes also feature some distinct differences that are important to make note of. Compression molding uses simpler machines, making it possible to produce a variety of basic plastic products. While both types of molding can yield high-volume output, compression molding is more affordable for building simple components that are strong and durable. Compression molding is also successful when manufacturing parts that vary in thickness from 1.3mm to 2.5cm. It is typically used as a mass production process to manufacture thousands of identical items. But in general, compression molding has advantages over injection molding. What is transfer molding? When using compression molding the cavity is slightly open when injecting and thus has more room for material. While some geometrical designs can be almost only be undertaken in an injection molding process, some materials can only be vulcanized using compression molding. Overmolding begins with the production of a substrate material in its own injection mold, done by injecting molten thermoplastic into the cavity and allowing it to fully cool.
