Quality Assurance:
Our quality assurance process for customized silicone dispenser check valves emphasizes precision, safety, and durability. Raw materials are carefully tested with spectrometers and durometers to confirm FDA and LFGB compliance. During production, CMM (Coordinate Measuring Machines), high-resolution projectors, and optical inspection systems ensure dimensional accuracy and flawless sealing edges. Mechanical tests, including air-tightness, opening pressure, torque, and fatigue life cycle testing, guarantee long-lasting and consistent valve performance. Every batch undergoes traceability control and cleanroom final inspection, ensuring compliance with international quality and hygiene standards. Our facility is ISO 9001 and IATF 16949 certified, guaranteeing repeatable, defect-free production.
