How Precision CNC Machining Serves the Global Sanitary Hardware Industry
Quality is the foundation of business survival. At HXINOX, we have established a complete quality management system, from raw material entry to finished product shipment, implementing strict inspection standards at every stage to ensure every product delivered to customers meets or exceeds expectations.
Incoming Quality Control (IQC)
Every incoming batch of SUS304/SUS316L stainless steel materials must undergo strict incoming inspection. We use spectrum analyzers to verify chemical composition, and calipers and micrometers to check dimensional deviations, ensuring materials meet ASTM, JIS, or GB standard requirements.
IQC Inspection Items
- • Spectrum composition analysis (Cr, Ni, Mo content)
- • Dimensional sampling (thickness, width, flatness)
- • Surface quality inspection (scratches, pits, scale)
- • Material certificate document verification
Process Quality Control (PQC)
During the CNC machining process, we implement multi-level process inspections. Operators perform First Piece Inspection every tool change or batch start. During machining, we use pneumatic gauges and digital micrometers for online detection, ensuring critical dimensions remain continuously controlled.
Finish Product Quality Control (FQC) & Outgoing Quality Control (OQC)
Every batch of shipped products must undergo 100% appearance inspection and full dimensional sampling inspection. We use projectors to check complex profile dimensions, and thread ring gauges and plug gauges to verify thread compliance, ensuring every connection to the customer's product achieves perfect fit.
Quality Commitment
ISO 9001:2015 certified quality management system, with annual batch qualification rate maintained above 99.5%. Every part delivered by HXINOX is proof of our commitment to quality.
