FRIMO HEAT STAKE RIVETING
Joining plastics and sheet metal
Riveting can be useful in situations where small parts must be joined together to form one large part. Many different riveting methods are used, depending on which materials must be processed. We offer technology-neutral advice and determine the most appropriate product-specific solution for your application. This is also particularly relevant for safety applications in the automotive industry, such as in airbag areas.
The high strength of rivets and gentle processing make this method ideal for surfaces with high quality finishes. Heat stake riveting is a cost-effective alternative to ultrasonic riveting because materials that become brittle during the ultrasonic process can be joined almost free of particles.
HEAT STAKE RIVETING PROCESS
Strong rivets from a gentle process
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. Once the power is off, cool air is used to cool the plastic. The punch is heated by a heating cartridge and monitored using a temperature sensor.
