The journey of a 50ml plastic centrifuge tube begins with the selection of high-quality raw materials, typically polypropylene (PP), which is known for its chemical resistance and mechanical strength. The manufacturing process involves several key steps:

Material Preparation: High-grade polypropylene pellets are carefully selected and mixed to ensure uniformity and consistency. This step is crucial as it lays the foundation for the quality of the final product.
Molding: The prepared material is then fed into an injection molding machine. Under high pressure and temperature, the molten plastic is injected into a mold cavity shaped like a 50ml plastic centrifuge tube. The mold is designed to create precise dimensions and features, such as graduations and caps.
Cooling and Ejection: Once the plastic has solidified, the mold opens, and the 50ml plastic centrifuge tubes are ejected. Rapid cooling is essential to prevent deformation and ensure dimensional stability.
