1. Selection of production environment

The suction head is used in molecular detection, in vitro diagnosis, preliminary screening and other experiments, so the pipette suction head has high environmental requirements for the production process, such as foreign biological pollution on the surface of the suction head will directly affect the analysis results. At present, the 100,000 dust-free workshop is the conventional choice.

2. Selection of production equipment

Suction head products have the characteristics of multi-hole, deep cavity, thin wall, fast molding cycle, etc., in the selection of equipment must have high molding efficiency, low failure rate and long-term stable operation, so high-speed electric injection molding machine is the best choice, characteristics are as follows:

The high-speed electric injection molding machine can meet the requirements of precision thin-walled products and reduce the straightness of the pipette head formed by the suction head during the forming process.

3. Process precautions

The main adverse phenomena of suction head products are head shortage, bending deformation, head and mouth raw edge, dimensional stability and other problems
