INTRO-SERT Ultrasonic Inserts offer plastic molders and users impressive benefits in lower cost production and better quality assemblies. In addition, they offer a choice of installation methods with conventional high frequency ultrasonic production equipment or the Yardley Thermal Inserter for low volume work. Advantages • Reduces molding cycle time by eliminating placing of inserts into mold cavity • Requires less costly mold construction yet provide more design latitude for molded parts • Rounded annular ribs reduce the stress concentration that causes residual cracking • Offer high resistance to rotation and pull-out •Adaptable to automated, high volume production Available from stock in Brass, Aluminum and Stainless Steel Custom sizes/materials available Recommended starting hole sizes: Tests should be conducted to determine the appropriate hole sizes for your specific application and base material.
