What is the process of elastomer casting?
The process of elastomer casting involves pouring a liquid elastomer material into a mold to create a solid, flexible product. This method typically begins with preparing the mold by applying release agents to prevent sticking and ensuring easy removal of the finished part. The liquid elastomer is then mixed with curing agents and additives to achieve the desired properties before being poured into the mold. Once poured, the material is allowed to cure and solidify, usually through a chemical reaction or heat activation. After the curing process is complete, the mold is opened, and the newly formed elastomer part is removed, ready for further processing or use in various applications. Elastomer casting allows for intricate shapes and designs to be produced with precision while maintaining the material’s unique properties such as elasticity and durability.
