Standardized Manufacturing
13-Step Precision Manufacturing Process
Every orthopedic implant manufactured at Zhejiang INAR Medical Co., Ltd. strictly adheres to a traceable 13-stage manufacturing and inspection workflow.
2 
Longitudinal Cutting
High-precision automated lathes cut certified metal bars into exact dimensional blank lengths for trauma plates and intramedullary nails.
3 
Precision CNC Machining
Multi-axis Swiss CNC machining centers execute complex anatomical contours, variable-angle screw holes, and locking threads with tight tolerances.
4 
Surface Polishing
Deburring and edge polishing to eliminate micro-burrs and ensure smooth surface finishes required for anatomical tissue contact.
5 
Ultrasonic Washing I
Multi-frequency ultrasonic bath removes residual machining oils, fine particulate matter, and contaminants prior to grinding operations.
6 
Precision Grinding
Fine grinding treatment to refine dimensional tolerances and verify plate profile uniformities across complex geometry curves.
7 
Sand-Blasting
Micro-bead sand blasting creates uniform matte surfaces to prevent optical glare under surgical illumination lights.
8 
Penetrant Testing
Non-destructive liquid dye penetrant testing inspects 100% of critical structural features for micro-cracks or material discontinuities.
9 
Anodizing & Color Coding
Electrochemical Type II anodizing provides corrosion resistance and vibrant color coding for surgical size differentiation.
10 
Ultrasonic Washing II
Final multi-stage purified water ultrasonic bath removes anodizing residue and pre-packaging micro-particulates.
11 
OQC Inspection
Outgoing Quality Control verifies thread gauge fits, laser markings, surface roughness, and dimensional tolerances against approved technical drawings.
12 
Aseptic Packing Cleanroom
Implants pass into a controlled Class 10,000 (ISO Class 7) aseptic cleanroom for double-pouch sterile barrier sealing.
13 
Packing Line & Labeling
Products receive UDI barcoded labels, protective outer box packaging, and multi-language instructions for use (IFU).
✓ 
Warehouse Storage
Temperature and humidity-controlled warehousing ensures safe storage before international air or sea freight dispatch.
