Utløsningsstoffer

Utløsningsstoffer, also known as release agents or parting agents, are chemical substances applied to a mold surface to prevent a molded part from sticking to the mold. This is crucial in various manufacturing processes, including plastics molding, rubber molding, die casting, and composite manufacturing, where it facilitates the easy and clean removal of the finished product. Without an effective release agent, parts can be damaged during demolding, leading to scrap, increased production time, and potential damage to the mold itself.

The mechanism of action for release agents typically involves creating a barrier between the mold surface and the material being molded. This barrier can be physical, formed by a layer of the release agent, or chemical, where the release agent reacts with the mold surface or the molded material to form a low-adhesion interface. Release agents can be applied in various forms, such as liquids, pastes, aerosols, or powders, and their selection depends on factors like the molding material, mold material, temperature, pressure, and desired surface finish of the part. Common types include silicone-based, wax-based, and fluoropolymer-based agents, each offering different performance characteristics. Proper application and maintenance of release agents are essential for efficient and high-quality production.
