LSR Injection Molding

Seehope brings your most complex designs to life with high-precision, automated LSR injection molding. Delivering purity, consistency, and performance for critical applications worldwide.

Seehope is proud to expand our expertise with state-of-the-art Liquid Silicone Rubber (LSR) production. Unlike traditional compression molding, our LSR process utilizes automated injection technology to produce parts with superior consistency, intricate detail, and zero contamination risk. Whether you require micro-molded components for medical devices or durable seals for automotive systems, Seehope offers scalable solutions tailored to your exact specifications.

• Unmatched Precision:​ Achieve tight tolerances and complex geometries with minimal flash, reducing secondary processing costs.
• Superior Material Properties:​ Excellent thermal stability (-50°C to 250°C), electrical insulation, and transparency.
• Automated Purity:​ Closed-system injection molding minimizes human contact, meeting stringent FDA and ISO 13485 cleanroom standards.
• Versatile Over-Molding:​ Expertly bond LSR to engineering plastics (PC, ABS, PP) and metals for multi-functional components.
• Rapid Cycle Times:​ High-efficiency curing enables faster production speeds for high-volume orders.

• Medical & Healthcare:​ Respiratory masks, catheter components, surgical seals, and wearable device straps. (Biocompatible & FDA compliant).
• Infant Care:​ Bottle nipples, pacifiers, and teething toys. (Non-toxic, odorless, and LFGB certified).
• Electronics:​ Waterproof gaskets, connectors, and protective keypads.
• Automotive:​ Gaskets, O-rings, and vibration dampeners resistant to extreme temperatures.

All Seehope LSR materials are platinum-cured and available in various durometers (Shore A 10-80). We ensure compliance with international standards including FDA, LFGB, USP Class VI, and ISO 10993. Our facility operates under strict ISO 9001 and ISO 13485 quality management systems.
