QC / Technical Support
Our in-house QC staff perform stringent quality inspection according to ISO 9001-compliant guidelines. For special testing projects, we collaborate with the Testing Center at Shanghai Research Institute of Material, Shanghai Fasteners Testing Center, and Zhejiang Standard Part Testing Center. 5 dedicated QC staff ensure every shipment meets international standards.
Quality Control Process
IQC — Incoming Quality
Testing reports required for every lot of raw material from material suppliers. Direct sourcing from qualified suppliers for our processing workshops.
IPQC — In-Process
Optical Monitor System (OMS) on each equipment to improve qualification rate. Screen graders separate scrap from product continuously.
OQC — Outgoing
All QC test results linked to computer system — detailed reports on core hardness, surface hardness, drilling test, torque, bending, zinc-plating specs.
FA — Failure Analysis
Managerial and technical staff study each reject carefully to prevent recurrence and continuously improve processes.
