Liquid Silicone Rubber Moulding Process

Injection molding of liquid silicone rubber lsr is a process used to produce pliable durable parts in high volumes.

Liquid silicone rubber moulding process.

Unlike compression molding the mold is first closed and then material is introduced into the cavities through a system of sprues runners and sub runners. An injector a metering unit a supply drum a mixer a nozzle and a mold clamp among others. Manufacturers commonly use liquid injection molding lim to form liquid silicone rubber lsr. Liquid silicone rubber is a high purity platinum cured silicone with low compression set great stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts where high quality is a must.

Liquid silicone rubber moulding is a thermoset process that mixes a two component compound together which is then heat cured in the mould with a platinum catalyst to produce a final lsr part. While the traditional reaction injection molding rim process focuses on a pressurized impingement mixing process liquid injection molding is comprised of a mechanical mixing method that blends a two component compound together in a mold. Due to the thermosetting nature of the. We use aluminum molds that offer cost efficient tooling and accelerated manufacturing cycles and stock various grades and durometers of lsr materials.

During the process several components are necessary. Liquid silicone rubber molding our liquid silicone rubber molding process produces custom prototypes and end use production parts in 15 days or less. Liquid silicone rubber injection molding is a thermoset process that cools the material delivery system while heating the mold tool to cure silicone material into parts. Once the parts are cured the mold is opened parts are removed and the process repeats.
