Heat staking methods

Clean and irremovable

bdtronic offers thermal riveting processes that heat and form the rivet pin in a controlled manner. All process steps are monitored. A very clean, maximum strength and reproducible result is obtained. Thermal riveting processes are suitable for processing all thermoplastics in mating with the same or other materials such as plastics, metals or printed circuit boards. 

The type of heat input is divided into conduction (hot stamp process), convection (hot air process), radiation and friction. bdtronic only uses processes that fall under conduction and convection. The advantage of these processes is that no contaminating chips or dust are produced, no embrittlement of the thermoplastics and no vibrations occur. In addition, the process is gentle on electronic components and demanding thermoplastics, very high strengths can be reproducibly achieved, and decorative surfaces are not damaged.

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.

Heat staking methods

Heat staking method BHS HOT AIR®

The BHS HOT AIR® hot-air riveting process is a two-stage joining process. This allows the cycle time of the machine to be significantly reduced.

Heat staking method BHS HOT STAMP® 

The BHS HOT STAMP® heating stamp process is particularly suitable for temperature- and pressure-sensitive components and riveting environments as well as for confined installation spaces.
