When is which heat staking process suitable?
When selecting the suitable riveting process, component restrictions such as temperature-critical areas, necessary clearance areas around the rivet points, interference contours, or maximum permissible mechanical loads must be taken into account. In addition, the requirements on the riveted joint, axial strength requirements, radial strength or special rivet head shape, also play an important role. And last but not least, the required machine cycle time and production environment can determine the choice of process.
A hot-stamp process applies the lowest thermal and mechanical stress to the component and offers the highest flexibility for special tools or installation situations. A hot-air riveting process achieves the highest possible axial strength and gap filling (radial strength or positioning and tight fit) and a homogeneous rivet head formation.
