In part 1 of this series, we looked at liquid injection molding (LIM) and how it compared to other types of molding for medical device manufacturing. In this blog, we will take a deeper dive into the silicone liquid injection molding process.
What Are the Materials Used in Liquid Injection Molding?
Silicone is typically used in liquid injection molding (LIM). It is a type of synthetic liquid rubber. There are different manufacturers and durometers of silicone that can be used in LIM, each with benefits and uses for specific applications.
Liquid Silicone Rubber (LSR), typically platinum cured silicone, is probably the most common type of silicone used in liquid injection molding. It is biocompatible and very durable, making it the silicone of choice for medical devices and instruments.
Fluoro Liquid Silicone Rubber (F-LSR), using fluorosilicone, as its name suggests, incorporates the element fluorine as a way to improve chemical resistance in the final product. Fluorosilicone is a popular choice for automotive parts as well as precision parts and tinier parts or parts.
