POLYURETHANE & SILICONE CASTING
Providing end-use, rigid plastic, rubber, and silicone parts with production-level quality since 1987
Fabrication Versatility
Mina Product Development can silicone cast or compression mold low to high volume projects. We have a wide variety of materials available at our disposal including: Shore A, Shore D, Conductive, and More.
Silicone Molds
We provide silicone mold fabrication services. This process includes 3D printed master patterns to silicone molds for prototypes and low volume production parts. We can cast both silicone and polyurethane materials.
Production
We are an ISO 13485 and 9001 certified business. All of our projects require strict record keeping. Material certs, ROHS compliance, and FA documents available.
No Minimum
There is no minimum order when fabricating silicone prototypes or proof of concept parts. We have completed a wide variety of projects from army/navy components to custom seals and gaskets for both the medical and science industries.
Medical Prototypes
At Mina Product Development we specialize in RTV silicone molds and cast urethane products for the medical & science industries. Cast urethane products are nearly identical to their injection molded counterparts, can be color matched, and will save you thousands on tooling.

Urethane Casting
How it Works
(Poly)Urethane casting is a method of manufacturing custom parts that are made by injecting urethane into a silicone mold. Molds are made by 3D printing a master pattern(s), then using those patterns to create cavities which we then pour silicone or urethane into.
What Can You Make?
You can urethane or silicone cast almost any shape in our custom molds. We have fabricated fully functioning medical prototypes to clear overmolded components used for military and scientific applications.
Limitations?
Our silicone molds have a lifespan of anywhere from 20-30 parts, dependent upon part geometry and material selected. Our urethane casted parts can be sanded and painted, and can even withstand the installation of plastic or metal inserts.
