OEM Liquid Injection Molding Food Grade Leak-proof Silicone Valves For Hydration Bottle Manufacturing

Description:

Our OEM Liquid Injection Molding Food Grade Leak-proof Silicone Valves are engineered with precision to provide superior flow control and consistent leak-proof performance for hydration bottles and sports drink systems. Manufactured from 100% FDA- and LFGB-compliant liquid silicone rubber (LSR), these valves combine exceptional elasticity, biocompatibility, and durability. Through advanced liquid injection molding technology, each valve achieves uniform wall thickness, flawless sealing geometry, and high production efficiency. Capable of withstanding temperatures from –40 °F to 450 °F, these valves maintain flexibility, hygiene, and safety across diverse environments. We offer full OEM customization—including slit design, durometer adjustments, color variations, and branding integration—to meet your exact application requirements. As a trusted silicone solutions partner, we deliver scalable, eco-friendly alternatives to traditional plastic valves that enhance both performance and user experience.

Basic Information:

Benefits of Our Products:

• Leak-Proof Performance: Precision-engineered slit and duckbill designs ensure one-way flow with no leakage, even under pressure.
• Food-Grade Safety: Manufactured from FDA- and LFGB-approved LSR, free from BPA, phthalates, and harmful additives.
• Durability & Flexibility: Excellent tear strength, elastic recovery, and resistance to high/low temperatures.
• Custom OEM Solutions: Tailored valve geometries, hardness, and branding options to meet your unique requirements.

Quality Assurance:

Quality assurance for our food-grade silicone valves is anchored in strict compliance with international safety and performance standards. Every batch of LSR raw material undergoes verification for BPA-free and FDA/LFGB compliance. During production, we employ high-precision molding and automated inspection systems to guarantee consistency. Performance testing includes leak-proof validation under pressure cycling, Shore A durometer hardness checks, tensile and tear strength analysis, and accelerated aging in thermal and humidity chambers. Flow-rate calibration ensures optimal liquid dispensing performance. Each valve is subjected to endurance testing simulating thousands of squeeze cycles, while surface treatments and geometries are verified using optical projectors and adhesion testers. All products are manufactured in our ISO 9001- and IATF 16949-certified facility under strict traceability and cleanroom-controlled processes.
