White Label Silicone Membrane Diaphragm Valves Suppliers

Overview

Our White Label Silicone Membrane Diaphragm Valves deliver precision, leak-proof fluid control for industrial, food, and analytical systems. Manufactured from high-purity LSR via cleanroom injection molding, the flexible diaphragm ensures reliable sealing and precise actuation. We provide complete white label services—from custom engineering to private branding—making us your seamless manufacturing partner for high-performance valve solutions.

Features

Production Process

1. Material Selection & Compounding: We select premium-grade, platinum-cured LSR. For specific applications, additives for enhanced chemical resistance or color are uniformly compounded under controlled conditions.

2. Precision Mold Manufacturing: The core and cavity molds for the critical diaphragm are CNC-machined from hardened steel (e.g., Stainless 420). Mirror EDM is used to achieve optical-grade surface finishes on sealing lands, while Slow Wire EDM ensures perfect alignment.

3. Cleanroom LSR Injection Molding: The LSR is injection molded in a controlled, low-particulate environment. This process forms the flexible, flash-free diaphragm with exacting tolerances for thickness and geometry, crucial for consistent actuation.

4. Valve Assembly & Integration: The molded silicone diaphragm is assembled into the valve body (metal or plastic). Critical steps include aligning the diaphragm with the seat and securing it with the housing, often using automated fixtures.

5. Functional & Leak Testing: 100% of valves undergo bubble-point or pressure decay leak testing to verify sealing integrity at various pressures. A sample from each batch is subjected to cycle life testing to validate durability.

6. White Label Packaging & Documentation: Finished valves are cleaned, packaged in plain or custom-branded boxes with protective inserts, and shipped with all necessary compliance documentation under your brand name.
