Medical Injection Molding PA66+GF30+15PTEE Injection Pen Large Push Rod

The large push rod of medical injection molding PA66+GF30+15PTEE injection pen is carefully made of advanced PA66+GF30+15%PTFE (polyamide 66 plus 30% glass fiber and 15% polytetrafluoroethylene) composite materials. This material combination not only gives the pushrod mechanical strength and wear resistance but also significantly improves its chemical resistance and low friction coefficient, ensuring high precision and smoothness during frequent use. The PA66 base material is based on its rigidity and heat resistance, combined with the reinforcement of 30% glass fiber, so that the large push rod can withstand greater injection pressure without being easily deformed, effectively extending the service life of the injection pen. At the same time, the added 15% PTFE (polytetrafluoroethylene), known as the "King of Plastics", with its lubricity and self-lubricating properties, significantly reduces the friction resistance between the push rod and the pen body, making every time drug injection smoother and smoother, reducing the patient's discomfort during use. In addition, the material has passed strict medical-grade biocompatibility testing to ensure that it will not affect the drug ingredients when in contact with the drug, ensuring patient drug safety. The injection molding process ensures the dimensional accuracy of the push rod and the flawless surface quality, and every detail reflects the unremitting pursuit of medical quality.
