Why Choose Us?

We build a steel mold and produce ​real parts in a few days!

Real Molds

The tool is made from steel, not aluminum. Our competitors use aluminum to manufacture tooling for their customers. Aluminum bends, warps, or otherwise loses its shape after minimal use. This leads to the items being made by that tooling having inconsistent tolerances and other undesirable characteristics.

Real Parts

We work with a large list of materials every day and we have done so for 20 years. We’ve developed deep expertise in the handling and manipulation of these materials. So, we can offer our customers the highest quality service from an informed perspective. Some of the materials we use are EPDM、SBR、NBR、HNBR、Butyl、Flourosilicone、Silicone.

Real Fast

With our experience of 20 years of Custom Molded Silicone Rubber parts. we will work with you to bring your project from design all the way to completion with the first article parts in days or a few weeks, not months. For example, we’ve made production tooling and shipped 10,000+ custom silicone parts in 9 days.
