One of the first steps in setting up a successful project is to determine the right material. The liquid silicone injection moulding process uses a two-component material, consisting of an A-component (catalyst) and B-component (cross-linker). By cross-linking (vulcanizing) the still liquid mixed components, the compound is subjected to pressure and temperature and converted into a dimensionally stable product. After cooling, products will have the desired hardness and specific electrical, thermal, and mechanical properties. If requested, both dyes and function-dependent components can be added to the base material during the process. Enbi Plastics also ensures the compounding of certified mixtures, for which additives have been pre-mixed in the basic material.
Just as with thermoplastics, product developers may choose from different types of LSR. For instance, a project may require a silicone material that is self-adhesive, self-bleeding, or oil-resistant. In fact, a combination of multiple properties is also possible. In addition, you can choose from a range of hardness values per type, ranging from 3 to 80 Shore A.
