Heat/Ultrasonic Inserts are designed for post-mold installation in thermoplastics. Heat and ultrasonic installation yield outstanding performance results. Available in long and short variations, long for maximum torque and pull-out resistance; short for less stringent requirements with the benefits of lower cost and reduced installation time.
Series 19 is designed for straight holes using standard core pins. The same hole diameter applies to all inserts within these series. Seating and installation are facilitated with a pilot and a tapered knurl and groove design.
Series 20 is a headed version using the same body style as Series 19.
