Liquid Injection Molding (LIM) of Liquid Silicone Rubber (LSR)

IMG_5028Our Liquid Injection Molding capabilities include Liquid Silicone Rubber (LSR) process technologies for both clear and colored silicone parts.

Liquid Silicone Rubber (LSR) is a proprietary name for a range of two-component Liquid Silicone Rubbers used to produce elastomer parts by injection molding. Because of its high thermal stability, good rubber-like properties and resistance to aging, LSR is the material of choice by many industries including medical, military, electronics, appliance, automotive and textile industries. The material has a wide temperature range (-94 degree F to +400 degree F) with low compression set and resistance to the damaging effects of sunlight and ozone.

LSR Engineering utilizes Engel E-Motion 310/100 Horizontal/Horizontal and Arburg Allrounder 800-150 Vertical/Vertical which allows us to handle a wide variety of Liquid Silicone Rubber mold sizes and styles. LSR Engineering has developed a modular mold base system which is set up to receive a standard cavity block size which we keep in stock. This modular system allows us quicker deliveries of Liquid Silicone Rubber Molding and our customers a substantial savings because they only purchase the cavity blocks and not the entire mold.

LSR Engineering has clean room capabilities at a class 100,000 or ISO 8 level. Using a new 10×10 portable clean room we can set-up our work space to the clean manufacturing requirements of various customers including medical device manufacturers of non-implantable custom molded parts and assemblies.

Molds for Liquid Silicone Rubber (LSR) require precision throughout the mold building process. Detailed designs, proper material selection, state of the art machinery utilizing the latest machining techniques and highly skilled mold makers are keys to success for every mold produced.
