This video from BTM Automation Products shows one of its hand-held clinching tools in action. BTM says that its Tog-L-Loc® and other related clinching tools join sheet metal quickly, quietly and cleanly without the expense of welding or the use of additional fasteners: the process simply clinches the parent material
Assembly cost is significantly reduced by drawing and forming the material to be joined into an interlock. Usefully, the process can join galvanized, pre-painted or even dissimilar metal combinations using an environmentally friendly process that does not produce sparks, harmful fumes or damaging heat.
BTM Automation Products confirms that it has extensive project experience and has provided joining solutions for a variety of household brands for decades. Its tools, processes and presses can be used to join sheet aluminium, steel and sandwiches of dissimilar materials too.
