The Two-Phase Thermoforming can be used for all thermoplastic materials; therefore, plastic-plastic and plastic-metal can be assembled without any problems.
It has significant advantages over traditional thermal staking, ultrasonic staking, and IR processes such as the infra-stake. With traditional processes, the proximity of the forming tips is limited by either the diameter of the transducer or the diameter of the heating device. The Thermoforming process is not limited by these constraints since the gas delivery nozzles can be placed as close as 3-4mm center-to-center.
This procedure is well suited to connect components through a backlash-free and positive-locking rivet connection. The rivet connection is formed by the thermal shaping of a rivet peg to generate high-strength joints.
