In the design and manufacture of medical injection molds, product design plays a pivotal role. A correct and reasonable product design directly impacts the quality of the final product. So, what basic principles should we follow when designing plastic products for medical injection molds?

Firstly, the shape design of the product should strive for symmetry, and the structure should be kept simple. At the same time, the external appearance should also pursue aesthetic beauty to meet the dual needs of medical products for both aesthetics and practicality. A symmetrical shape design not only facilitates uniform filling during the injection process but also effectively reduces defects caused by uneven flow. A simple structure, on the other hand, can reduce the difficulty and cost of mold manufacturing, improving production efficiency.

Secondly, we must select the correct plastic variety and grade based on the actual usage requirements of the product. Different plastic materials have their unique performance characteristics, and only by choosing the right material can we ensure that the product meets its functional requirements. In addition, reasonably determining the dimensional tolerances of the product is also crucial. Excessive tolerances may lead to difficulties in fitting or assembly, while too tight tolerances will increase manufacturing costs and difficulty.

Lastly, we must fully consider the characteristics of the injection molding process. In the design of the product's structure and shape, we should strive to align with the injection molding process to ensure the appearance quality of the molded product. At the same time, we should also optimize the design to reduce the cost of injection molding and improve production efficiency.
