Silicone Compression Molding


Compression molding has been used to mold rubber parts since the beginning of the rubber manufacturing industry. It is one of the oldest methods still used to mold rubber parts. JunYi is a silicone molding company that has utilized compression molding since the year 2010. Silicone compression molding offers JunYi's customers an effective and efficient way to manufacture low-volume production parts.

The compression molding process is quite simple when compared to injection molding, transfer molding or extrusion molding. JunYi will manufacture a compression mold tool which requires CNC machining and hand polishing. Once the tool is ready for engineering samples, then each plate is loaded with liquid silicone rubber. Simple part designs typically only require a two plate mold, which includes a cavity side and a core side. After the material is loaded, the mold plates are assembled and inserted into a compression molding press between the two platens. Next the press is clamped to a set pressure to produce high quality parts. Heat and pressure are applied for a given amount of time allowing the liquid silicone to spread throughout the mold cavity and cure. Then pressure is released from the press, which then opens and the compression mold is removed. Then the plates are separated using hand tools and finally the silicone part is removed. This completes a normal compression molding cycle for a simple silicone part design.

JunYi has a range of differently sized compression molding presses in both our controlled environment room and on our production floor. This ensures that we can run small to large sized parts and single cavity molds, as well as multi-cavity ones in either space. If needed, we can easily configure our molding equipment and space to meet our customers' demand for production.
