Waterproof Precision Parts

LSR Sealing Solutions for Automotive, Consumer Electronics & Mobile Devices

Industry Overview

Waterproof sealing is critical for automotive connectors, mobile phones, consumer electronics, and countless other applications. LSR (Liquid Silicone Rubber) provides excellent sealing performance, temperature resistance, and long-term reliability.

YRlims Technical has extensive experience in waterproof precision parts. Our products are widely used in smartphones, earphones, consumer electronics, and automotive industries. We understand the demanding requirements for leak-proof sealing in various environments.

Technical Challenges

Mold Precision

Waterproof sealing parts require extremely tight tolerances. Mold precision directly affects sealing performance and consistency.

Air Leak Testing

Every sealing part must pass rigorous air leak testing to ensure zero leakage under specified pressure differentials.

Temperature Resistance

Automotive parts typically require 10+ years service life with extreme temperature resistance. LSR provides excellent thermal stability from -60°C to +200°C.

Compression Set

Long-term sealing requires minimal compression set—LSR maintains elastic recovery even after prolonged compression.
