But what’s clear now was not so obvious five years ago when NSI began its search for a better tip technology. NSI’s R&D staff set their sights on finding an injection moldable, medically safe, user-friendly material from which to mold their “tips of the future. “They began by modifying existing materials such as ABS, nylon, and Delrin, but that brought them no closer to their goals. Finally, after exhaustive testing, high-impact modified vinyl plastic emerged as the material they were looking for. The problem then facing the R&D team was how to produce this new material using existing machine tools and injection molding equipment Twenty-five versions of the original formula were evaluated before the company discovered the optimum temperature level and injection speed. Tool designs and injection molding techniques also had to be modified to obtain the desired results.
