Compression molding, also known as compression moulding, has become the most commonly used manufacturing process in industries ranging from industrial to maternal and baby. Generally speaking, common materials for compression molding include granular, powdery, fibrous or preformed plastic. In this article, we focus on silicone compression molding. High consistency rubber (HCR silicone), also known as solid silicone rubber or thermoset rubber, is a synthetic elastomer containing the elements silicon, oxygen, carbon, hydrogen, and other elements that add the desired properties, with unique Chemical structure, temperature resistance, and aging resistance. The Compound processing method for this different combination of properties is usually compression molding.
