Liquid Silicone Rubber (LSR) injection moulding represents a peak technology in modern elastomer manufacturing. Unlike traditional high-consistency rubber (HCR) processing, which relies on solid gum stock, LSR injection moulding utilizes a two-part liquid compound (Component A containing a platinum catalyst, and Component B containing the methyl-hydro siloxane crosslinker) mixed in a 1:1 ratio. This material is injected into heated mould cavities to induce rapid vulcanization and polymerisation.
This method delivers unmatched precision, outstanding thermal resilience, flexibility down to -60°C, stability up to 250°C, and superb biocompatibility. In highly demanding fields like medical device manufacturing, automotive electric powertrains, infant care, and aerospace engineering, LSR molding has become the standard design choice.
"By integrating advanced mechanical automation with material chemistry, LSR molding eliminates secondary finishing operations and ensuresflash-free, high-tolerance components directly from the demolding cycle."
China's manufacturing ecosystem provides a powerful combination of low-cost raw material production and high-precision mould tool engineering. Leading factories leverage fully automated closed-loop systems, integrating dosing units directly with high-performance injection machines.
By partnering with local chemical providers and utilizing China's massive liquid rubber feedstock chain (including LSBR, CTBN, and specialty polyethers), Chinese factories offer cost-effective production without sacrificing material purity. This complete integration—from base silicone monomers to advanced high-precision tooling—allows global engineering teams to reduce capital tooling costs by 40% to 60% compared to Western alternatives, while matching or exceeding equivalent quality standards.
When specifying LSR grades for custom projects, engineers must map physical requirements to specific material attributes. The table below lists standard engineering classes of liquid silicone rubbers typically processed in high-end China factories:
| LSR Grade Type | Durometer (Shore A) | Tensile Strength (MPa) | Elongation at Break (%) | Key Industrial Standards |
|---|---|---|---|---|
| Standard Industrial Grade | 30 - 70 | 6.5 - 9.0 | 350 - 550 | RoHS, REACH, UL94-HB |
| Food Contact Grade | 40 - 80 | 7.5 - 10.0 | 300 - 500 | FDA 21 CFR 177.2600, LFGB |
| Medical & Biocompatible Grade | 20 - 80 | 8.5 - 11.0 | 450 - 650 | ISO 10993, USP Class VI |
| Self-Lubricating Grade | 30 - 60 | 6.0 - 8.5 | 300 - 450 | Automotive Gasket Specs |
| Flame Retardant (Self-Extinguishing) | 50 - 70 | 7.0 - 9.5 | 250 - 400 | UL 94-V0 Classification |
LSR pricing structures depend on tooling configuration and processing variables. Standard price lists typically separate costs into non-recurring tooling engineering and per-piece manufacturing rates:
To maintain high reliability, YANXA's partner manufacturing network complies with ISO 9001:2008 and updated ISO 9001:2015 frameworks. Medical component molding is conducted inside Class 100,000 (ISO Class 8) and Class 10,000 (ISO Class 7) cleanrooms to prevent particulate contamination.
Our strict quality control procedures rely on automated visual inspection machines, optical comparators, and coordinate measuring machines (CMM) to verify critical dimensions within ±0.05mm tolerances. Material validation includes full certificate of analysis (COA) documentation, material test reports, and compliance certificates for USP Class VI and European LFGB standards.
Our quality control systems ensure thorough monitoring at every stage of production. Process controls track temperature, injection pressure, and cycle times to prevent defect formation.
Partner facilities are certified to ISO 9001, providing international-grade manufacturing and document tracing for global automotive and industrial projects.
We process non-toxic, eco-friendly liquid rubbers. Production systems utilize energy-saving servo motors and minimize material waste through optimized runner designs.
