LSR Injection Molding for Flexible Production Parts

Liquid silicone rubber molding uses a low-viscosity, two-component silicone system that is metered, mixed, injected into a heated mold, and cured into a permanent thermoset elastomer. It is a strong fit when parts need flexibility, compression recovery, biocompatible material options, or resistance to heat, weathering, and many chemicals.

  • Two-part thermoset silicone molded in heated tooling for stable elastomeric parts
  • Useful for seals, gaskets, valves, wearable components, medical parts, and high-temperature assemblies
  • Material options can include standard, medical-grade, optical-grade, and fuel- or oil-resistant silicone

How Liquid Silicone Rubber Molding Works


Upload Your LSR Design

Share your CAD file, expected use environment, sealing surfaces, and target durometer.

Review Material and DFM

We review parting lines, flash-sensitive areas, wall transitions, draft, and material fit before tooling.

Mold and Cure Parts

The two-part LSR is mixed, injected into heated tooling, cured, and removed as a finished elastomeric part.

Inspect and Ship

Finished parts are checked against cosmetic, dimensional, and functional requirements before delivery.
