Silicone Casting

Molded production-quality custom silicone parts that are a superior alternative to 3D-printed “rubber-like” parts


Eliminate Metal Liquid Silicone

Rapid Silicone molding process helps engineers to entirely eliminate the need for metal liquid silicone rubber (LSR) molds.

Faster Shipping for Parts

Silicone Molded Parts can often be shipped in as little as two days after order receipt

Volume Production Available

TriMech can complete delivery of many low- to medium-quantity jobs in under two weeks.

Why choose Molded Silicone Parts?

The limited performance characteristics of 3D-printed elastomers can offer serious challenges. It’s common for 3D-printed elastomer prototypes to tear or break, sometimes very quickly, during mechanical testing. This is especially true with 3D-printed parts that have thin features or with very flexible printed parts.

As a better option, TriMech offers durable molded silicone prototypes and production parts in a wide range of durometers and custom colors.

TriMech proprietary Rapid Silicone low-volume molding process creates highly stress-resistant prototypes and end-use parts with custom-blended colors. Standard material durometers range from Shore A 15 to Shore A 60, with custom formulations available.
