The processing of medical molds relies on their reasonable and accurate structural design. For example, for transparent products, hot runners should be used as much as possible to minimize fusion traces; when cold runners are used, the runner size should be shortened as much as possible. In addition, disposable medical devices are characterized by small size and large batch, so automatic unloading, shearing, and pouring can be used to ensure stable capacity and quality. Medical products often have a lot of transparent tubular parts, so when designing the mold, attention should be paid to the gate feeding position and the fixing method of the moving mold, to avoid the improper selection of the gate position and the fixing method of the core, which will lead to uneven material flow and deformation of the core during the injection molding process.

    As a matter of fact, medical molds sometimes have uneven products or can't be filled with products, to solve this problem, it is necessary to do the shape of the exhaust expansion tube should be suitable and the overflow should be good, to avoid the air confinement that causes the product molding difficulties. In addition, the cooling system of medical molds should adopt multiple independent cooling channels, reasonably control the temperature of moving and fixed molds, and control the product deformation. Therefore, medical molds require close parting surfaces in the manufacturing process, and the precision of the molds is ensured through equipment processing. The fixed-dynamic mold core of transparent products should also be finely polished to ensure that the Ra value is above 0.20. Liquid polishing method can be used if required.
