Compression Molding for Healthcare & Medical Components
Lowering upfront investment
Compression molding is an effective and efficient method for low-volume production of liquid silicone rubber (LSR) molded parts. In comparison with other molding methods, compression molding combines the production of components in complex geometries with lower tooling investments and shorter lead times.
Lower upfront tooling cost
Shorter tooling lead time
Lower material scrap than injection or transfer molding methods
Process suitable for most elastomers and curing systems
Compression Molding Process
The compression molding process begins with a piece of uncured rubber, which has been specially weighted and preformed. These pieces are then placed into each of the mold cavities. The mold is then closed, forcing the preform into the shape of the part. The elastomer is held under pressure until the rubber achieves the required amount of crosslinking. Flash is removed and the parts are placed in an oven for post curing to achieve a fully cured finished part.
Healthcare & Medical Application Examples
Compression molding is generally used in applications where custom shapes are needed such as diaphragms for respiratory equipment, lip seals for cylinder applications or isolation bumpers used to inhibit vibrations.
