What's New?

Liquid Silicone Rubber Injection Molding (LSR injection molding) has been widely used in many markets due to its ability to produce intricate elastomeric components with relatively short cycle times.

The automotive industry uses silicone's high degradation temperatures for engine sealing and medical components markets rely on its biological inertness. Liquid Silicone Rubber (LSR) can be processed using slightly modified thermoplastic molding equipment, making them easy to integrate into existing business structures and facilities. Also, an increase in use has driven down the raw material cost of LSRs as to make them more competitive with historically less expensive thermoplastic elastomers, thus extending their use into new markets in recent years. An increase in specialized auxiliary equipment such as demolding devices will further facilitate LSR push to the mainstream of polymer manufacturing.

Among the whole silicone material, Liquid Silicone Rubber (LSR) has a relatively short history.
Developed during the late 1970s, LSR two component systems have quickly increased in popularity over the past 30 years due to their
advantages over Gum Silicone Rubbers. Not only are faster cycle times and flashless molding possible, but all secondary equipment is contained near the molding press and there is no need to mill or process the material in any way prior to use. Also , LSR is popular due to its ability to compete with typical thermoplastic elastomers which allowing for minimal initial capital investment.

In next part, we will try to write something about the material and the process about the liquid silicone rubber molding, kindly contact for more details .
