QUALITY CONTROL
Throughout our evolution, we have refined a meticulous multi-step process to ensure each component surpasses stringent quality and functionality standards, commencing even before raw materials are acquired. Initially, incoming raw materials undergo an acceptance sampling method to determine acceptance. Accepted materials undergo thorough cleaning, full inspection, and minor imperfection rectification before warehousing. Subsequently, following initial assembly and brazing, each product undergoes individual visual inspection and a preliminary hermeticity test, employing a helium leak test tailored to client specifications. Post-plating, batches undergo sampling inspection and coating bonding degree analysis. Approved products undergo an extensive inspection process, meticulously assessing appearance, construction, plating thickness, and undergoing a secondary helium tracer gas hermeticity test. Subsequently, products undergo a range of Factory Inspection trials, including pin fatigue and salt spray corrosion resistance tests, alongside climate simulation analysis for performance evaluation. Approved products are then vacuum-packed with deoxidizing desiccant inserts and additional protective packaging before shipment, ensuring consistent high-quality delivery.
