Quality Control Highlights
Our quality management system guarantees batch-to-batch consistency and full material traceability for global distributors.
13-Stage Orthopedic Production Workflow
From certified raw bar stock to sterile packing, each production step is subject to strict in-process quality control (IPQC).
Raw Material Receiving
100% inspection of medical-grade titanium alloy (Ti6Al4V ELI) and PEEK bars with chemical certificate verification.
Longitudinal Cutting
Precision sizing of bar stock using high-speed automatic longitudinal cutting machines to ensure accurate blank dimensions.
CNC Machining
High-precision multi-axis CNC milling and turning for anatomical plate contours, locking threads, and screw flutes.
Surface Polishing
Deburring and mirror polishing to eliminate stress concentration points and improve biocompatibility.
Ultrasonic Washing I
Multi-stage ultrasonic degreasing and cleaning to remove machining oil and particulate residues.
Grinding & Refining
Micro-grinding of edge profiles and instrument tips to ensure precise mechanical tolerances.
Sand-Blasting
Controlled micro-bead blasting to achieve specified surface roughness for optimal bone-implant interface adhesion.
Penetrant Testing (NDT)
Fluorescent dye penetrant inspection under UV light to detect micro-cracks or surface discontinuities.
Electrochemical Anodizing
Type II anodizing and vivid color coding to facilitate quick intraoperative identification during surgery.
Ultrasonic Washing II
Pure deionized water ultrasonic rinsing for final pyrogen and particulate decontamination prior to packaging.
Outgoing Quality Control (OQC)
Final optical coordinate measurement and 100% sampling audit before authorization for packaging.
Aseptic Cleanroom Packing
Sealing implants in sterile blister packs or protective bags inside controlled ISO Class 8 (100,000 class) cleanrooms.
Final Packaging Line
Custom OEM/ODM box labeling, UDI barcode printing, and protective packaging compliant with global export standards.
Warehouse Storage
Climate-controlled inventory storage ensuring safety and rapid worldwide dispatch to B2B distributors.
