For our compression molding process, Joey Tech uses high-quality silicone that is cross-linked using either peroxides or a platinum catalyst. The choice of cross-linking agent depends on the specific product’s technical requirements. Before the molding process begins, each mold cavity is carefully filled with a precisely measured amount of uncured silicone. This precision ensures minimal material waste, uniform part quality, and reduces the need for post-production trimming.

Achieves tight tolerances and complex geometries with exceptional accuracy.

Produces strong, flexible, and long-lasting parts resistant to extreme temperatures.

Ideal for medical and baby products, meeting FDA and other regulatory standards.

Highly automated process that ensures consistent quality and faster production times.

In compression molding, uncured silicone material is placed directly into a preheated mold cavity. Once the mold is closed, hydraulic pressure is applied to press the material into the desired shape. The silicone is then heated to 150°C – 200°C, initiating the vulcanization process where the material is cured to achieve its final form. The result is a strong, durable part with excellent material properties, including resistance to temperature extremes, chemicals, and mechanical stress.

Compression molding is ideal for producing simple, large parts with durable characteristics. The process offers high efficiency for high-volume production runs, while ensuring that parts are consistently of high quality.

Injection molding is especially recommended for high volume production of small to medium sized components such as:

Teats for baby bottles
Medical components
Sealing rings
Suction cups for the automation of production processes

Material selection

Both solid silicone and liquid silicone are suitable materials for injection
