A large amount of plastic is used in medical devices. Most of its production methods are injection molding.Therefore, it can be said that a considerable part of medical devices requires the use of molds in the production.Representative plastic medical devices are shown below.1. Syringe (needle): PP,

The thermoplastic resin used for injection molding is injected into the cavity of the mold in a state of heating and liquefaction, and its heat is taken away by contacting the surface of the mold, and then cooled and solidified.At this time, the volume in the liquid state is reduced by the volume co

The corrosion resistance of the injection mold cavity depends on the steelThe corrosion resistance of an injection mold cavity depends on the steel. Corrosive components from the forming material and moisture in the air promote oxidation of the steel surface, leading to corrosion.

How to improve the rigidity of the injection moldInjection molds are subject to high internal pressures when filling with molten resin and high compressive stress when closing the mold. In addition, large molds are subject to bending stresses due to their own weight.Therefore, the rigidity of the mo
