What is LSR Injection Molding?
Liquid Silicone Rubber injection molding represents a sophisticated thermosetting process ideal for manufacturing complex, high-performance elastomeric components. Unlike conventional rubber processing, LSR begins as a two-part liquid system that transforms into durable, temperature-resistant parts through controlled heat activation. At RT Manufacture, we've perfected this advanced manufacturing technique to deliver components with exceptional dimensional stability and material consistency.
Our LSR Injection Molding Capabilities
As a specialized provider of liquid silicone rubber molding services, we integrate cutting-edge technology with extensive material expertise:
√ Advanced Molding Systems: Our LSR manufacturing cells incorporate precision temperature control and cold runner technology, eliminating material waste while maintaining part consistency.
√ Material Expertise: We work with certified LSR grades compliant with ISO 13485 (medical), UL, and automotive specifications.
√ Quality Assurance: Every injection molded LSR component undergoes rigorous verification against dimensional and performance specifications.
LSR Material Advantages & Applications
| Key Property | Technical Benefit | Industry Applications |
| Superior Temperature Resistance | Maintains performance from -40°C to 225°C | Automotive gaskets, appliance seals |
| Medical-Grade Biocompatibility | Complies with USP Class VI & ISO 10993 standards | Surgical instruments, drug delivery components |
| Precision Moldability | Fills intricate geometries with tight tolerances | Microfluidic chips, electrical connectors |
| Optical Clarity | Transparent formulations with light transmission up to 95% | Optical lenses, light guide elements |
| Chemical Inertness | Resists sterilization methods and harsh chemicals | Laboratory equipment, industrial seals |
Custom LSR Manufacturing Process
Our comprehensive approach ensures seamless project execution from concept to production:
1. Design Optimization: Our engineering team analyzes part designs for manufacturability, suggesting enhancements for optimal performance.
2. Tooling Development: We build high-precision molds with certified mold steels, incorporating advanced gating and venting systems.
3. Validation & Sampling: We produce initial samples for approval, conducting dimensional verification and functional testing.
4. Volume Production: Our batch manufacturing is tracked by dedicated personnel to ensure the consistency of batch production parts.
5. Post-Molding Operations: We provide value-added services, including deflashing, packaging, and assembly.
