Ketchup Valve Injection Molding Silicone Umbrella Valves Suppliers

Overview

Our Ketchup Valve Injection Molding Silicone Umbrella Valves offer reliable, no-drip dispensing for food packaging. Engineered from food-grade Liquid Silicone Rubber (LSR) via precision injection molding, the umbrella design ensures positive sealing against backflow and contamination. We provide full OEM services for custom sizes, flow rates, and cracking pressures to meet your specific condiment and sauce packaging requirements.

Basic Information

Production Process

1. Design & Engineering: We analyze flow requirements to design the valve’s umbrella geometry, stem, and flange for specified cracking pressure and flow rate.

2. Precision Mold Manufacturing: Multi-cavity, hot-runner molds are CNC machined and finished with EDM to achieve critical sealing surfaces and tolerances.

3. LSR Injection Molding: Food-grade LSR is injection molded in a controlled environment, forming the flexible, one-piece umbrella valve structure.

4. Post-Curing & Deflashing: Parts are post-cured for optimal properties, then automatically deflashed to ensure clean edges and consistent performance.

5. 100% Functional Testing: Every valve undergoes automated leak testing and may be sampled for flow rate verification to guarantee sealing integrity.

6. Custom Branding & Packaging: Valves are packaged per specifications, with optional molded-in logos or batching for traceability.
