Before (改善前)
When manufacturing medical products, sterilization is often required. There are three main sterilization methods: radiation sterilization, electron beam sterilization and gamma sterilization, or ethylene oxide gas sterilization (EOG). The cost required for each sterilization work is also different, but there are cases where the design instructions are ambiguous, the type of sterilization is not specified and specified unnecessary sterilization works, it may result increase costs.

After (改善後)
For medical applications, if a sterilization process is required, it is necessary to perform radiation sterilization such as electron beam sterilization and γ-ray sterilization or ethylene oxide gas sterilization (EOG) after plastic molding. Generally, electron beam sterilization can be performed in the shortest time and can be performed at low cost. However, because of its low permeability, sterilization with high-density products requires gamma-ray sterilization. In addition, ethylene gas sterilization (EOG) can degrade not only bacteria but also DNA, so it is effective for sterilization of reagent containers.
POINT(要約)
Medical plastic injection moldings often require a sterilization process. Depending on the required specifications of the product, a test for killing microorganisms may be performed as necessary. In a prototype / development project, a material inspection may be performed by inspecting the state of material deterioration of the product due to radiation. Because which sterilization method is most suitable depends on the material properties, a detailed sterilization validation test enables verifications and sterilization conditions suit for the product.
