Heat staking methods

bdtronic offers both BHS HOT STAMP® and BHS HOT AIR® heat staking methods. Depending on the component and requirement, we select the appropriate process for your product.

Clean and irremovable methods

bdtronic offers thermal riveting processes that heat and form the rivet pin in a controlled manner. All process steps of the heat staking methods 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 (BHS HOT STAMP® method), convection (BHS HOT AIR® method), radiation and friction. bdtronic only uses methods that fall under conduction and convection. The advantage of these methods 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 method suitable?

When selecting the suitable heat staking method, 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® method 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 method achieves the highest possible axial strength and gap filling (radial strength or positioning and tight fit) and a homogeneous rivet head formation.
