Key Quality Points of Medical Test Tube Moulds

  • High concentricity and inner bore dimensional consistency ensure accurate tube volumes and eliminate errors.
  • Balanced multi-cavity design guarantees consistent weight and dimensions across all tubes to avoid quality variations between batches.
  • Mirror-polished cavities minimize liquid residue, ensuring precision and reliability in laboratory applications.
  • Balanced hot runner manifold processing Precision flow channel machining for hot runner manifold. Even melt distribution to all 16 cavities, minimal flow mark, stable filling, small product weight difference among cavities.
  • Spare Parts are standard interchangeable, easy for maintenance and replacement

Precision Machining Highlights for Medical Test Tube Moulds

  • CNC high-speed precision machining with critical dimensional tolerances controlled to ±0.01 mm ensures high mould accuracy.
  • Multi-process inspection, including concentricity, bore diameter, length, and wall thickness, guarantees high-quality centrifuge tube moulds.
  • Mirror polishing & ultra-smooth surface ensuresNo burrs, no scratches, no pits. It meets medical clean requirements, avoids sticking, and ensures good transparency of PP/PET test tubes.
  • Independent cooling circuit precision drilling  Accurate water channel layout and high-precision deep hole drilling. Uniform cooling of each cavity, short cycle time, low deformation and stable dimension repeatability.
  • Synchronized ejection structure precision fit Precision grinding for ejector pins, sleeves and guiding parts. Small matching clearance, stable synchronous demoulding, effectively prevent thin tube deformation, cracking or sticking on core.
