Thermoplastic thermoforming

The Two-Phase Thermoforming process connects two different kinds of materials given that one of these materials is thermoplastic. There are no problems in riveting/staking parts with critical surfaces (painting, foil, graining…) Particle free welding process In this process, the plastic pin is plasticized and gets softer with a contactless heating source which eliminates friction and particles. No pollution on the heating element No material adhesions on the tools even for materials with low viscosity because of the contactless plasticization and “cold” forming punch. Lower mechanical stress on the components Since force is applied in the 2nd phase when the plastic pin is already plasticized by a non-contact heating element, it reduces mechanical stress. Reduce cycle time with Rotary Table Heating, turning, and riveting can be separated in three steps using a rotary/turntable to reduce cycle time. It also has the ability to simultaneously riveting (more than 30 points are proven). 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.
