Liquid Silicone Rubber Injection Molding

21 January 2021

Following our vision for constant inovation, and to satisfy the needs of our customers, we have invested in a new 160T injection machine featuring a Liquid Silicone Rubber (LSR) injection unit. This new Arburg machine, along with 5 others, is part of the investment made in our new factory.

Liquid Silicone Rubber

LSR is an elastomer which has become the choice material for the manufacturig of many products due to its durability and high resistance to temperature and chemicals. Liquid silicone rubber’s mechanical and electrical properties make it ideal for insulation and conductivity protection.

Liquid silicone rubber results from adding two components – a catalyst and a cross linking agent. A dosage system mixes both, as well as dyes and additives if desired. This new mixture is then injected and vulcanizes rapidily at very high temperatures. Often, liquid silicone is overmolded onto other parts made of different plastics.

This material has thousands of aplications in several industries, such as electronics, auto, aerospacial, garden tools, etc. Because of its biocompatibility it has great usage potential in the medical field, especially in the manufacturing of organs, membranes and prosthetics.

Typical applications for liquid silicone rubber are products that require high precision such as seals, sealing membranes, electric connectors, baby and children’s products where smooth surfaces are desired, ( eg. bottle nipples), medical applications as well as kitchen goods such as baking pans, spatulas, etc.
