Blood collection tubes are essential for diagnostics, medical research, and laboratory
testing. Behind each tube is a highly precise injection mould engineered for accuracy,
safety, and regulatory compliance. This blog walks through the journey of blood
collection moulds — from design to final production.
Understanding Blood Collection Moulds
Blood collection tubes (PET or PP) require tight dimensional accuracy because they
interact directly with analyzers and must maintain sterility and vacuum integrity.
Common Components Produced:
- Tube body
- Cap & closure
- Rubber stopper
- Needle hub components
Step 1: Design & Engineering
1. Material Selection
PET and PP are most commonly used due to clarity, chemical resistance, and
bio-compatibility.
2. Dimensional Precision
Blood tubes must maintain strict tolerances to ensure proper sealing and
compatibility with automated systems.
3. Gate & Runner Optimization
Hot runner systems are typically used to reduce contamination risks and ensure a
smooth internal surface finish.
Step 2: Mould Manufacturing
High-Precision CNC & EDM
Each cavity is machined with ultra-precision equipment to maintain:
- Smooth surfaces
- Uniform wall thickness
- Zero flash zones
Advanced Cooling Channels
Efficient cooling reduces cycle time while preventing warpage — critical for
medical-grade tubes.
Step 3: Validation & Testing
Before production begins, blood collection moulds undergo:
- Dimensional quality checks
- Leakproof testing
- Impact resistance tests
- Sterilization compatibility evaluation
Step 4: Production & Automation
Medical moulding facilities typically use:
- Class 100,000 cleanrooms
- Robotic part handling
- In-line inspection systems
Why High-Quality Blood Collection Moulds Matter
Medical moulding facilities typically use:
- Ensures consistent vacuum
- Prevents contamination
- Maintains accuracy during diagnostic testing
- Supports high-volume, 24/7 production

Conclusion
From engineering design to automated production, blood collection moulds require
precision, innovation, and reliability. With rising global healthcare demands,
high-performance mould technology is more important than ever.
