Our liquid silicone rubber (LSR) molding process enables the production of custom prototypes and end-use production parts in 15 days or less. We utilize aluminum molds, providing cost-effective tooling that not only accelerates manufacturing cycles but also ensures a high-quality finished product.
Low-volume production
Bridge tooling
Pilot runs
Functional prototyping
Our basic guidelines for silicone rubber molding include important design considerations to help improve part moldability, enhance appearance, and reduce overall production time. By following these design principles, you can optimize part functionality and aesthetics.
