Medical Injection Molding PBT+20%GF Injection Pen Push Rod Rotating Barrel

Medical injection molding PBT+20%GF injection pen push rod drum is specially designed for high-precision medical injection pens. It is molded through precision injection molding technology to ensure a balance between structural strength and dimensional accuracy. The application of PBT+20%GF material not only gives the push rod drum mechanical properties, including high strength, high rigidity, and fatigue resistance, allowing it to maintain stable performance and durability during frequent operations. At the same time, the addition of glass fiber also significantly improves the material's thermal deformation temperature and creep resistance, ensuring that it can maintain its shape even under high temperature or sustained pressure environments, and extending the service life of the product. In terms of design, the injection molded accessory has a smooth and delicate surface and a low friction coefficient, which reduces irritation to the patient's skin during use and improves the user experience. Its internal precision structure works closely with the injection pen mechanism to ensure accurate drug dosage, which is an important guarantee for the safety of medical injections. In addition, the material also has good biocompatibility and chemical stability, and will not adsorb or contaminate drugs, ensuring the safety and effectiveness of drugs.
