Medical-Grade Silicone

Liquid silicone rubber molding or liquid injection molding (LIM) is a robust process used in the high volume, production stages of silicone component manufacturing. By this stage of the process, we would have gone through the silicone prototyping process and refined the part design and selected the appropriate material hardness and closed in on a silicone part geometry for your application.

The Material

The silicone material is supplied as a two-part drum (450lbs) or pail (40lbs) kit and this closed system reduces any chances of contamination. In this two component system, Part A contains the vinyl functional polymer and the catalyst and Part B consists of the crosslinker and inhibitor. The low viscosity material is pumped into the injection unit of the molding machine using a high precision silicone pump.

The Process

Liquid silicone molding is an effective way to achieve consistent part quality and improved productivity. The low viscosity or flow behavior of the material allows design of small, thin walled and geometrically complex shapes. The process also allows very fast cure times under 30 seconds. The molds are also designed to be high precision, eliminating material waste and any secondary operations.
