Heat / Ultrasonic Inserts are designed for post-mold installation in thermoplastics. Heat and ultrasonic installation yield outstanding performance results. SPIROL offers several different series of Heat/Ultrasonic Inserts available in a long and short version of each thread size. Long lengths maximize torque and pull-out resistance, while short lengths are good for less stringent requirements at lower cost and shorter installation times. Some styles are available with or without a head. The head provides bearing surface for the mating component that also prevents jack-out (or when used in reverse, can prevent pull through). However, adding a head results in additional cost raw material of a larger diameter is required to create the head. Some non-headed Inserts are symmetrical – thus eliminating the need to orient the Insert prior to installation. Excellent performance results can be achieved with Heat / Ultrasonic Inserts provided that they are used in the proper hole size with sufficient wall thickness around the Insert and they are installed in a manner that results in proper melting of the plastic to fill the voids of the Insert. Heat / Ultrasonic Inserts generally provide the best balance between performance and cost. SPIROL Standard Heat / Ultrasonic Inserts include: Series 14 for tapered holes, Series 19 & 20 for straight holes and Series 29 & 30 for straight holes. SPIROL’s Heat / Ultrasonic Inserts are available in thread sizes ranging from M2 (2-56) up to M8 (5/16-18).
