Customize Silicone Rubber Injection Molding Silicone Duckbill Umbrella Valves

Overview

Our Custom Silicone Duckbill & Umbrella Valves provide reliable one-way flow control and pressure relief for diverse applications. Manufactured from premium LSR via precision injection molding, they ensure leak-proof sealing and precise actuation. We offer comprehensive OEM services for custom design, sizing, and performance tuning to meet your specific fluid management needs.

Features

Production Process

• Material Preparation & Compounding: We select high-purity, platinum-cured LSR. For specialized needs, additives for enhanced chemical resistance or specific durometer (hardness) are uniformly compounded under controlled conditions.

• Precision Mold Design & Fabrication: Multi-cavity molds are engineered using CAD. Core and cavity components, especially for the delicate duckbill lips or umbrella seal, are machined from hardened steel using high-speed CNC and finished with Mirror EDM for flawless, micron-precise sealing surfaces.

• LSR Injection Molding: The prepared LSR is injected into the temperature-controlled molds in a clean environment. This process forms complex, undercut geometries like duckbill slits and thin umbrella membranes in a single, flash-free operation.

• Demolding and Post-Curing: Valves are automatically ejected after curing and undergo a secondary post-curing cycle. This step optimizes the silicone’s physical properties, ensuring long-term elasticity and performance stability.

• Trimming and Deflashing: Any microscopic parting line flash is removed via cryogenic deflashing or precision laser trimming to guarantee clean, functional edges that do not hinder sealing or flow.

• 100% Functional and Dimensional QC: Every valve undergoes an automated pressure decay leak test. Statistical samples from each production batch are tested for precise cracking pressure and flow rate using digital equipment.

• Final Inspection and Packaging: A final visual and dimensional inspection is conducted. Products are cleaned and packaged per your specifications, ready for integration or shipment.
