Clinch joining

TOX Pressotechnik has introduced 'Micropoint' technology which, says Sebastian Reichold, is "the answer to the miniaturisation of piece-parts.

"Until now there has not been a technical or an economical option to thermal joining techniques such as soldering, spot welding, projection welding, resistance welding, cool soldering, etc.

However, with the development of Micropoint joining technology it now is possible to join small steel parts for micro-system techniques; for example, contact elements, springs, and functional components or similar units made of relatively thin sheets by a safe and rational method."

Piece-parts of steel, copper, and aluminium can be joined - single thicknesses from 0.1mm; total sheet thicknesses of 1.2mm - "no matter whether the parts are tin plated, silvered, or coated with conductive grease. The result will be an absolutely mechanically reliable and electrically safe-conducting joining of components."
