Project Overview
Guangdong GRK (广东格瑞克), a leading manufacturer of blood collection systems, successfully deployed our Blood Collection Needle Visual Inspection & Sorting Machine for its operations in Singapore. This delivery marks another milestone in our cooperation with medical device manufacturers across Southeast Asia, and reflects the growing global demand for automated quality inspection in the medical consumables industry.
Client Background
Guangdong GRK specializes in high-precision medical consumables, with blood collection needles forming a core product line. The company serves hospitals, diagnostic laboratories and distributors across Asia and beyond. As overseas demand — especially from Singapore, a key regional hub for medical distribution — continued to grow, the company required a reliable, high-throughput quality inspection solution to guarantee the consistency and safety of every needle shipped.
Blood collection needles are critical single-use consumables used in phlebotomy and diagnostic testing worldwide. Each needle must meet strict dimensional tolerances for tip geometry, sharpness and surface finish. Any defect — however small — can cause patient discomfort, sample contamination or downstream testing errors, making 100% inspection essential for regulatory compliance and brand reputation.
The Challenge
- Manual inspection created a bottleneck in high-volume production lines.
- Human fatigue risked inconsistent defect detection and missed defects.
- Overseas clients demanded full batch traceability and regulatory compliance.
Our Solution: Blood Collection Needle Visual Inspection & Sorting Machine
We delivered a fully automatic vision inspection system engineered specifically for blood collection needles, combining multi-angle high-resolution imaging with AI-based defect classification and high-speed sortation.
Key Technical Features
- Multi-angle imaging: industrial-grade cameras capture top, side and 360° views to eliminate blind spots.
- AI defect classification: deep-learning models detect scratches, bent tips, burrs, contamination and structural abnormalities.
- High-speed processing: up to 6,000 needles per hour, a 5x improvement over manual inspection.
- Real-time sortation: pneumatic mechanism automatically separates qualified and defective needles into dedicated bins.
- Full traceability: each needle generates a digital quality record for batch traceability and SPC analysis.
