Westminster Tool Inc. designed and built a progressive, single-cavity unscrewing medical mold that uses a servo-driven motor for a customer’s medical device. The customer’s projecta surgical device that would be molded in a cleanroom environmentrequired a threaded core feature. The hydraulic power pack that is typically required for threaded cores did not meet cleanroom requirements because of the risk of contamination. Westminster Tool’s alternative solution uses a servo motor that integrates directly into the mold and provides tighter controls, greater accuracy and improved cycle time. Westminster Tool is a complex injection mold builder specializing in medical, aerospace and consumer packaging. Westminster Tool is in Booth 252 at Amerimold 2018.
