Your professional Sealing Tester manufacturer in China
Guangdong Fulistech designs and fabricates packaging seal integrity test systems. Our team handles full-cycle development: independent R&D, instrument assembly and pre-delivery calibration for seal testers within our facility.
We build custom test jigs for package leak testing and tailored leak testing setups for many specimen formats, including pharmaceutical blister pack seal testing, sterile medical pouch leak test, food sachets and lithium pouch cell seal integrity test.
Every tester undergoes calibration referenced to ISO 17025 traceable calibration for packaging testers before dispatch. Our calibration protocols comply with GB/T 15171-2025, YY/T 0681.18, ASTM F2338, ISO 11607 and USP <1207>. A traceable calibration certificate for GMP audit is supplied with each unit to support GMP audits.
Our standard 12-month warranty activates after on-site installation, commissioning and client acceptance. Our support team responds to fault alerts within 48 hours. Defective parts and repairs are free for quality failures during warranty. Out-of-warranty spare parts follow our official wear parts price list. We also deliver complimentary operator training for seal testing equipment.
