Silicone Compression Molding Capacities
Siliconexy is a silicone products molding factory that has utilized compression molding since the year 2005. Silicone compression molding offers Siliconexy‘s customers an effective and efficient way to manufacture their liquid silicone rubber prototypes and low-volume silicone production parts.
We specializes in providing custom silicone compression molding services for kitchen, home consumer goods, industrial, medical, automotive, consumer electronics, and engineering applications, ensuring consistent product quality and short lead times. As a trusted silicone molding partner, we meet high-volume orders, prototyping, and mass production needs worldwide.
What Is Silicone Compression Molding?
Silicone compression molding is a mature, high-efficiency rubber molding process that forms solid silicone rubber into custom-shaped parts using controlled heat, sustained pressure and precision-engineered molds.
This manufacturing technique is widely favored for medium-to-high volume production of complex silicone components, offering tight dimensional tolerances, premium material performance and minimal material waste.
Compression molding utilizes pre-measured solid silicone raw material (rubber slabs or pellets) placed directly into the mold cavity. The mold is clamped under high pressure and heated to cure the silicone, shaping it into the designed geometry.
It is the optimal process for solid silicone parts, gaskets, seals, bumpers, custom profiles and thick-section silicone components.
Advantages of Compression Molding
Thickness Control: This technology allows for flexible control of product thickness.
Seamless: One-piece molding with no seams or weaving marks. Silicone gaskets are a prime example of how silicone compression molding can produce consistent parts.
Lower Cost: As a low-pressure mold, multi-cavity production is more cost-effective.
Diverse Material Selection: Suitable for various silicone rubber materials, such as silicone and LSR, to meet different performance requirements.
Environmental Protection: The mold is reusable, consumes less energy, reduces material waste, and meets environmental protection requirements.
Wide Applications: Suitable for the production of both large and small parts, with a wide range of applications.
