Customized Medical Injection Mould Multi Cavites Blood Collection Tube Mould

Product Parameters

Medical test tube molds require a high degree of precision. For the mold plates, P20 or 718 is selected. For the inserts, S136 or 632 is used. The cores are all ground into a round shape through internal grinding. The cooling water system is extremely difficult to design because the cores are small, and the inner holes of the cores also need a cooling water design. Otherwise, the mold cannot work properly. The plastic materials used are PP (polypropylene), PS (polystyrene), and PET (polyethylene terephthalate) respectively. The injection molding cycle is about 18 to 20 minutes per mold. 

Characteristics of Plastic Materials and Injection Molding Time

1. Plastic Materials: Commonly used plastic materials for medical test tubes include PP (polypropylene), PS (polystyrene), and PET (polyethylene terephthalate). PP has good chemical stability, impact resistance, and high and low temperature resistance, making it suitable for manufacturing medical test tubes that require a certain strength and chemical corrosion resistance. PS has high transparency and gloss, and is easy to process and form, which is often used for medical test tube products with high requirements for appearance. PET has excellent mechanical properties, barrier properties, and transparency, and is often used for manufacturing medical test tubes that need to store liquids for a long time or have high requirements for sealing.

2. Injection Molding Time: The injection molding time of this mold is approximately 18 to 20 minutes per mold. The control of the injection molding time is closely related to the characteristics of the plastic materials, the structural design of the mold, and the efficiency of the cooling system. An appropriate injection molding time can ensure that the plastic is fully filled and cured in the mold, while avoiding the reduction of production efficiency caused by an excessively long injection molding time. By optimizing the cooling system of the mold and rationally selecting plastic materials, it is possible to shorten the injection molding time as much as possible and improve production efficiency on the premise of ensuring the quality of medical test tubes.

In conclusion, the design and manufacture of medical test tube molds require a comprehensive consideration of multiple aspects such as material selection, cooling system design, and injection molding processes to meet the requirements of the medical industry for high-precision, high-quality, and high-efficiency production of test tubes.
