Silicone Rubber Injection Molding Process

Why the preferred use of silicone rubber in injection molding.

Silicone rubber injection molding process.

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. As the shear rate rises the product becomes lower in viscosity. It is this effect that is very favorable for the injection molding process. The liquid injection molding lim manufacturing process molds silicone rubber into a broad array of parts and products.

Silicone injection molding is a manufacturing process developed for the molding of plastics while injection molding of silicone rubber began in the 60 s and 70 s. 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. Liquid silicone rubber is widely used in tod. They cure in heat and are ideal for manufacturing a variety of silicone rubber articles.

The liquid silicone injection molding process is highly automated with short cycle times to reduce the silicone part price. Silastic silicon rubber is a sheer material and so its viscosity depends on shear rate. Due to the thermosetting nature of the. Injection molding of liquid silicone rubber lsr is a process to produce pliable durable parts in high volume.

Elastosil r solid silicone rubber grades are peroxide curing. Injection molding successfully alters the process by heating the silicone rubber and placing it under significantly more pressure per square inch of cavity surface in the custom. Unlike the standard reaction injection molding process which relies on pressurized impingement mixing liquid injection molding uses a mechanical mixing process that focuses mainly on liquid silicone rubber lsr and similar elastomeric materials. Injection molding of liquid silicone rubber lsr is a process to produce pliable durable parts in high volume.
