OEM Compression Molding One Way Check Cross Slit Silicone Check Valve for Squeeze Bottle Cap Suppliers

Description:

Our OEM One-Way Cross Slit Silicone Check Valves are engineered for precision fluid control in squeeze bottle caps and dispensing systems. Manufactured from FDA-compliant, food-grade liquid silicone using advanced compression molding technology, these valves ensure consistent one-way flow, reliable sealing, and drip-free dispensing. The cross-slit design enables smooth, controlled release with minimal effort while preventing backflow, leakage, and product contamination. Designed to perform under repeated use, they withstand a wide range of viscosities—from water-like liquids to thicker gels and sauces. With full OEM customization, we support tailored slit geometries, durometer hardness, and color variations to meet specific application requirements. Our valves are ideal for food packaging, personal care, household products, and medical-grade dispensing solutions.

Basic Information:

Benefits of Our Products:

• Leak-Proof, Drip-Free Dispensing – Cross-slit valve design ensures one-way flow with no back leakage or product waste.
• Customizable Flow Control – Tailored slit dimensions and hardness adjustments optimize performance for different viscosities.
• Durable & Safe Materials – Manufactured with FDA- and LFGB-compliant food-grade silicone, free of BPA and harmful substances.
• Wide Application Range – Suitable for food packaging, cosmetics, household cleaning products, and healthcare dispensing systems.

Surface Treatment Options:

1. Polished Finish – Ensures smooth sealing surfaces and consistent dispensing.
2. Textured Finish – Improves grip and valve seating in bottle caps.
3. Plasma Treatment – Enhances bonding strength for overmolding or assembly with plastic closures.
4. Custom Coloring – Food-safe pigments available for branding and product differentiation.

Quality Assurance:

Our quality control process ensures reliability, safety, and compliance across every production run. Each batch undergoes raw material validation (BPA-free, FDA and LFGB compliance), Shore A hardness testing, tensile and tear strength verification, and thermal aging simulations to validate long-term durability. Flow performance is tested with precision dispensing rigs to ensure consistent actuation pressure and leak-free operation. Dimensional accuracy is monitored via 3D optical measurement, while accelerated life testing simulates thousands of squeeze cycles. All products are manufactured under ISO 9001 and IATF 16949-certified quality systems, with traceability and batch records maintained for strict process control.
