Processing medical injection molds and products is a highly specialized task that requires precise processes, strict quality control, and the use of materials that meet medical industry standards. The following is a detailed introduction to the processing of medical injection molds and products:
(1) Medical injection mold design
Before processing a medical injection mold, it is first necessary to carry out sophisticated design work. Designers need to take into account the functionality, size, material properties, and application scenarios of the final product. Medical injection mold design must follow strict medical standards, such as ISO 13485 or FDA guidelines, to ensure that the product is safe, reliable, and easy to sterilize.
(2) Material selection
Medical injection molding products usually use biocompatible materials, such as polycarbonate (PC), polyether ether ketone (PEEK), polyformaldehyde (POM), etc. These materials not only need to meet the biocompatibility requirements, but also need to have good mechanical properties and chemical resistance to ensure the stability and safety of the product in long-term use.
(3) Mold manufacturing
Mold manufacturing is a key step in the processing of medical injection molding products. The precision of the mold directly affects the quality of the final product. Therefore, in the mold manufacturing process, high-precision numerical control machine tools (CNC) are used for processing, and advanced testing equipment is used to ensure the size and shape accuracy of the mold.
(4) Injection molding process
Injection molding is the process of injecting molten plastic material into a mold and forming the desired shape after cooling. In medical injection molding, this process needs to be carried out under strictly controlled conditions, including temperature, pressure and injection time, to ensure product consistency and quality.
(5) Quality control
The quality control of medical injection molding products is very strict. Quality inspection is required at every stage of production, including raw material testing, mold inspection, injection molding process monitoring and final inspection of the finished product. In addition, biocompatibility testing, chemical tolerance testing and sterilization verification are also required.
(6) Sterilization and packaging
Medical injection molded products often require sterilization prior to final use, such as ethylene oxide (EO) sterilization or gamma ray sterilization. The sterilized product needs to be packaged in a sterile environment to prevent contamination.
