Mingseal implements a comprehensive Quality Control system that spans the entire product lifecycle—from R&D to after-sales service—ensuring high precision, reliability, and customer satisfaction.

We adopt a systematic product and process management approach, incorporating FBD, DFMEA, PFMEA, control plans, and SOPs. Key components like valves and controllers undergo in-house precision manufacturing, multi-stage inspection, functional testing, and aging verification to guarantee stable performance.

Advanced inspection and testing methods, including material incoming checks, process self-inspections, and finished product testing, are conducted using high-precision equipment to uphold stringent quality standards.

The ITE (Issue to Excellence) system enables closed-loop management of problems and needs—from data collection and analysis to root cause processing and control—driving continuous improvement and delivering full lifecycle protection for customer products and services.
