Key Quality Points of Centrifuge Tube Moulds
- High concentricity and inner bore dimensional consistency ensure accurate centrifuge 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.
- Stable hot runner temperature control system prevents injection moulding defects such as stringing, black spots, and short shots.
Precision Machining Highlights for Centrifuge 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.
- Ultra-precision polishing ensures smooth inner bore surfaces, reducing liquid adhesion and residue build-up.
- Wear-resistant reinforced slides and ejection systems ensure stable and durable operation of the centrifuge tube moulds under high-frequency production.
Mould Flow Analysis for Centrifuge Tube Moulds
Using Mouldflow analysis, we optimize the filling, packing, and cooling processes of the centrifuge tube mould. The analysis simulates the injection moulding process, optimizing cavity layout, gate positions, and temperature control solutions, ensuring uniform cavity filling and reducing air pockets, warping, and short shots, enhancing the moulding stability of the centrifuge tube mould.
