Custom Silicone Rubber Injection Molding Service For Your Business

Liquid silicone rubber injection molding parts have the feature of durability with good tensile strength and are used to high volume, tight tolerance. Therefore it is widely used in various industries especially for medical parts.

Here are the advantages of liquid silicone rubber:

Excellent insulating properties, good for tight tolerance/precision components

Good tensile strength with high/low-temperature extremes

Good resistance for water, oxidation also some chemical solutions like acids.

Silicone Injection Molding Process

The silicone dousing unit starts in two parts

Composed A and composed B pumps one Part A silicone and one Part B silicone via separate hoses to the static mixer. Cylinder A contains the basic material. while cylinder B contains a catalyst. In addition, color is pumped to the static mixer via another hose. The mixed components are then fed into the throat of the injection molding barrel by way of a shut-off valve. This is the whole silicone rubber injection molding process.

Sealing against the Silicone Rubber Molded Parts

Once the silicone material is inside the barrel, a shot of the cool mixed silicone advances to the mold as the nozzle seals firmly against the silicone rubber liquid mold.


The nozzle shut-off valve opens and a measured shot of cool liquid silicone is injected into a hot (275F to 390F) clamped silicone rubber molded parts.

Barrel retracts from the mold

The nozzle shut-off valve opens and the barrel retracts from the silicone rubber liquid mold, while the screw begins to build another measured shot of cold liquid silicone.

Closes and repeats the procedure

After the cycle is complete, the mold opens and the piece and flashing can be taken off automatically or by an individual worker. After that, the mold closes and repeats the procedure.

Post-molding process

After removing the article from the mold, the post-molding process may include demisting, post-curation, inspection, and packing.

Silicone Rubber injection Molding Application

Molding Parts

-Silicone rubber injection molding can be qpplied in molding parts. Moulded part is a good way for low quantity production from dozen to hundred of the part even millions of parts. The molding part is better than the part machined by CNC or 3D printing with the same material. The right choice for resin used in the molding part allows for a wide range of properties. Mold is essential medial for the molding part. So molds machined by CNC and Wire cut EDM with high precision and tolerance are enable make thousands of parts.


-We cercitified with ISO9001, ISO13485 and equipped with ISO 8 medical cleanroom molding
