Benefits of Our Products:

1. Consistent FDA-Compliant Material Formulation

Precision-engineered mixing and curing processes ensure uniform FDA 21 CFR 177.2600-compliant silicone compounds, eliminating contaminants while maintaining batch-to-batch reliability for food contact applications.

2. Tight-Tolerance Molding Capabilities

Advanced injection/compression molding techniques with CNC-machined tooling achieve ±0.004″ dimensional accuracy, ensuring leak-proof seals across production runs for standardized equipment fitment.

3. Thermal/Chemical Resilience Through Controlled Vulcanization

Optimized post-curing ovens and dwell-time protocols enhance cross-linking density, creating O-rings that withstand repeated -60°F to 450°F cycles and CIP/SIP sanitization without compression set.

4. Scalable Customization with Rapid Tooling

Modular mold designs and liquid silicone rubber (LSR) processing enable fast transitions between durometers (20-80 Shore A) and colors while maintaining food-grade certification compliance for OEM spec requirements.

Quality Assurance:

Quality assurance for OEM food-grade silicone rubber gasket O-rings includes a rigorous series of steps to ensure product safety, reliability, and compliance with industry standards. Our factory adheres to ISO 9001 certification, ensuring strict quality control processes throughout the production cycle. Each O-ring undergoes comprehensive testing using advanced equipment such as tensile testers, hardness testers, and leak testers, to verify material integrity, dimensional accuracy, and sealing performance. Additionally, we conduct tests for FDA and LFGB compliance, confirming that all silicone materials are safe for direct food contact. These quality control measures guarantee the consistent production of high-performance, food-safe silicone rubber O-rings.
