Heat Stake Riveting

Joining/Gluing: FRIMO Heat Stake Riveting

Riveting can be useful in situations where, for example, small components must be joined to form one large component. Many different riveting methods are used, depending on which materials must be processed.

In heat stake riveting of thermoplastic materials, the plastic is plasticized with the electrically heated riveting punch at the point of contact. It is then formed and pressed together under pressure. Switching off of the electricity begins the air cooling. The punch is heated by a heating cartridge and monitored using a temperature sensor.

Heat stake riveting is suitable not only for thermoplastics, but also for steel-plastic connections. This is also particularly relevant for safety applications in the automobile industry, such as in the airbag segment. The high strength of the rivets and gentle processing also make this method ideal for surfaces with high quality finishes.

In addition, heat stake riveting is a cost-effective alternative to ultrasonic riveting.
