Precision Liquid Silicone Rubber (LSR) vs Compression Molding for Custom Parts

2026-10-11

latest company news about Precision Liquid Silicone Rubber (LSR) vs Compression Molding for Custom Parts

Choosing the Right Molding Process

Liquid silicone rubber (LSR) injection and compression molding both produce custom silicone parts, but they suit different geometries and volumes. Dongguan Yunze Silicone Products Co., Ltd. runs both processes to match each project.

Process Comparison

When to Choose LSR

Pick LSR for high-volume, high-precision, or miniaturized parts where repetition matters.

When to Choose Compression Molding

Pick compression molding for prototypes, low volumes, and large parts.

Applications

  • Medical and infant-care components
  • Automotive seals and gaskets
  • Consumer electronics keypads

Frequently Asked Questions

Which process gives tighter tolerances?

LSR injection generally achieves tighter, more repeatable tolerances.

Can you run a bridge tool?

Yes, compression tooling can validate designs before LSR investment.
