Pipette Tip Moulds
SINO MOULD has extensive experience in the development and production of pipette tip moulds, serving the laboratory consumables and life science industries. For pipette tips of different specifications—such as 10μL, 200μL, and 1000μL—we focus on 32–128 cavity high-precision multi-cavity moulds. Leveraging advanced machining equipment and strict quality control, we provide laboratory consumables manufacturers with stable, reliable, and high-consistency mould solutions.
Pipette tips produced by our moulds feature high concentricity, smooth inner surfaces, and excellent alignment, ensuring accuracy and consistency in practical use.

Key Quality Points of Pipette Tip Moulds
●High concentricity and inner bore dimensional consistency to ensure accurate liquid aspiration volume.
●Balanced multi-cavity design to guarantee consistent weight and dimensions across all pipette tips
●Mirror-polished cavities to minimize liquid residue and wall adhesion risks
●Stable hot runner system to prevent stringing, black spots, and short shots
Precision Machining Highlights for Pipette Tip Moulds
- CNC high-speed precision machining with critical dimensional tolerances controlled to ±0.01 mm
- Multi-process inspection: concentricity, bore diameter, length, and wall thickness
- Ultra-precision polishing applied to critical forming zones ensures the smoothness of the inner bore.
- Slide and ejection systems undergo wear-resistant reinforcement for sustained high-frequency operation
Mould Flow Analysis for Pipette Tip Moulds
Using Mouldflow analysis, filling balance, gate location, and temperature distribution are optimized to ensure uniform cavity filling, reduced air traps, and stable moulding quality.
