Liquid Silicone Injection Molding (LSR)

One of the many specialty services and capabilities that we offer our customers is Liquid Silicone Injection Molding (LSR) with both bondable and non-bondable properties. This unique molding process and unique material is still in its infancy and very few suppliers offer its manufacturing advantages.

The use of liquid silicone has expanded significantly in the markets of Medical Devices, Consumer Products, Automotive, and Industrial applications. The expectation is that liquid silicone use within manufacturing will expand tremendously over the next few years as new liquid silicone compounds and technologies develop further.
