Benefits of Our Products
-
Precision LSR Injection Molding: Ensures unmatched part-to-part consistency, flash-free edges, and dimensional stability crucial for reliable, automated assembly and consistent sealing performance.
-
Guaranteed One-Way, Leak-Proof Function: The umbrella valve design provides a reliable seal against backflow, preventing leaks, drips, and oxidation to extend product shelf life and enhance consumer satisfaction.
-
Superior Material Performance: Offers excellent chemical resistance, enduring elasticity over thousands of actuations, and stability across extreme temperatures without cracking or degrading.
-
Engineered Customization: We tailor the valve’s stem diameter, skirt thickness, slit configuration (I, X, or custom), and opening pressure to precisely control flow rate for any product viscosity, from water-thin to paste-thick.
Quality Assurance
Our quality assurance for custom LSR umbrella valves is built on a foundation of certified materials and rigorous validation. Operating within an ISO 9001-certified system, we enforce strict controls from raw material inspection (using only FDA-compliant LSR) through final production. Every batch undergoes comprehensive testing, including dimensional analysis with optical measurement systems, durometer verification, and—most critically—functional performance testing. This includes seal integrity pressure tests, cycle life testing (exceeding 10,000 actuations), and flow rate calibration to ensure each valve delivers reliable, leak-proof operation as specified.
