FRIMO HEAT STAKE RIVETING
Joining plastics and sheet metal
When individual components need to be assembled on a larger module, riveting processes are used. During heat stake riveting, thermoplastics are melted at the contact point with a heated staking unit. They are then formed and pressed together under pressure. Once the power is off, cool air is used to cool the plastic. This process is well-suited for sheet metal and plastic combinations and is therefore great for a variety of applications with a mix of materials.
Springloaded staking units allow for different heights of riveting points in processes with different materials. Space and process-optimized FRIMO heat stake riveting machines are extremely compact. They can be installed in the tightest spaces and give you the advantage of efficiency. Along with the standard machine, project-specific production layouts can be created, as well as combined and special solutions.
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.
