Many people are familiar with injection molding or plastic molding but not all are familiar
with compression molding
Compression molding is a molding process whereby the pre heated molding material, goes in an open, heated cavity. The mold is closed with a plug and pressure is applied to force the plastic or rubber into contact with all mold areas while applying heat and pressure. Compression molding uses thermosetting compounds and is is a high-volume, high-pressure method suitable for molding complex reinforcements.
Compression molding is often used for making electrical parts, flatware, gears, buttons, buckles, knobs, handles, cases, housings, and large containers.The advantage sof compression molding include setup costs, quick setups, large size parts, intricate pieces and a nice finish.
Companies that manufacture parts from compression molding include Reliance Engineering.
Injection molding machines with high positioning accuracy and high repeat-ability such as our hydraulic and electric ALLROUNDERs, are in demand for compression injection molding. You must be careful when selecting compression technology and for the design and layout of the mold.
