This term refers to an auxiliary substance used in plastics processing to prevent a molded part from adhering to the surface of the mold. By applying this substance to the mold surfaces, the demolding of plastic parts becomes easier and the risk of damage or surface defects is reduced. Such agents are particularly used in processes such as injection molding, compression molding, or laminating. They can be applied as a spray, liquid, or solid coating and form a thin separating layer between the mold and the plastic material. This supports a reliable and consistent demolding process.
Injection molding process: Applying the release agent to the ejector side of an injection mold
