Customized One Way Silicone Check Duckbill Valves for Water Bottle Application with Custom Shape Solution Suppliers

Overview:

Our Customized One-Way Silicone Check Duckbill Valves for Water Bottle Applications are engineered for reliable, leak-proof one-way dispensing in reusable bottles, sports caps, and hydration systems. Manufactured via precision LSR injection molding from food-grade LSR or food-grade silicone, each duckbill valve delivers low opening pressure, fast reseal, and long cycle life. We provide full OEM customization—duckbill geometry, lip thickness, hardness, color, and branding—plus prototype validation and scalable volume production to meet beverage and houseware performance and safety requirements.

Features:

• Place of Origin: Xiamen, China

• Shape: Duckbill (custom shapes and lip profiles)
• Hardness Range: Shore A 30–40 (customizable)
• Process: LSR injection molding, silicone compression molding, micro die-cutting, post-molding slit cutting
• Tolerance: ±0.02 mm (typical, customizable)
• MOQ / Samples: Small orders & prototype samples available
• Lead Time: Samples 5–7 business days; Production 15–30 days (depending on tooling)
• Certifications: ISO 9001, RoHS; options for FDA, LFGB documentation on request
• Packaging: Custom protective packaging & traceable lot labeling
• Primary Applications: Reusable water bottles, sports caps, beverage dispensers, travel mugs

Surface & Finish Options:

• Color masterbatch (transparent, translucent, opaque)
• Hydrophobic / anti-wetting coatings for reduced dripping
• Food-safe release layers for improved demolding and low friction(UV Coating)
• Sterilization-compatible finishes (EtO / autoclave validation available)

Quality Assurance:

Raw materials are verified via supplier certificates and incoming tests; production uses automated LSR dosing with closed-loop process controls. Dimensional checks (3D optical, CMM), slit geometry inspection, opening-pressure & leak tests, cyclic life testing (>100k cycles), and migration/chemical resistance checks ensure consistent performance. Each lot is traceable with full inspection records and conforms to our ISO 9001 quality management protocols.
