Rubber/silicon Compression Molding Applications

Rubber/silicon compression molding is widely used for part production in industrial, housewares, food, medical.

Typical parts include:

Rubber/silicon Compression Molding

This process involves labor-intensive silicone rubber, specifically a pre-catalyzed product made by adding powder to silicone. This makes it easier for the silicone to cure once heat is applied.

Adding pigment to the silicone is performed by mixing via a two-mill roll. This is where the labor-intensive part comes into play. There’s a big risk of contamination to the silicone during this stage.
Once the material has been pre-catalyzed and pigment has been added, technicians will then weigh it and shape it to match the needed size and configuration of the part in question.
They then put it into the mold cavity for formation, compressing the rubber between the top and bottom plates.
The plates are then heated to melt and cure the silicone.
Compression molding happens to be the most basic and simplest form of silicone rubber molding, but as we said earlier, it’s a very open-air labor intensive process. In terms of cost, fillers can be added to the silicone to reduce the cost of manufacturing the material.
