Injection-Compression Molding

­Injection-compression molding is a modification of the injection molding process to produce large, complex, and thin-walled, as well as micro-structured, and low-tension plastic components.
Pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured.

The process can be controlled by the closing units of the machine as well as by internal mold pressure. Either way the costs for tooling and  machines will increase, thus injection-compression molding will be used for producing components with features and qualities that can’t be realized using conventional injection molding procedures.
