The POM (polyoxymethylene) release button in medical injection pens, as one of the key accessories, demonstrates engineering performance and medical-grade safety standards. The release button is injection molded from high-quality POM material, which is popular in the medical field, especially precision injection equipment, for its high strength, wear resistance, chemical corrosion resistance, and low friction coefficient. In terms of design, the POM release button has undergone precise mold development and injection molding process control to ensure the precise size and smooth touch of the button, making it easy for patients or medical staff to operate with one hand and achieve easy and fast dose release. Its surface has been specially treated, which not only improves the anti-slip performance but also ensures hygiene and cleanliness under long-term use, effectively preventing the growth of bacteria. In addition, the stability of the POM material ensures the reliability of the release button under different environmental conditions (such as changes in temperature and humidity), preventing material deformation from affecting the accuracy and safety of the injection pen. The button has also undergone rigorous biocompatibility testing to ensure that it will not produce adverse reactions when in contact with drugs, providing patients with a safe and worry-free treatment experience.
