Bollhoff Rivclinch® is a specialized joining technology used for steel, stainless steel, aluminum and other non-ferrous materials. “Clinching” is a non-fastener, non-adhesive technique used to assemble two or more different pieces together by cold forming (pressing) the materials together. The connection is a permanently formed round or square indentation (point) that is a form-fitting, non-positive connection. Joining two or more layers together are possible – whether they are painted or coated – without damaging the surface.

There are Many Advantages to Using a Rivclinch® Metalforming System:

  • Joining time is performed in less than a second
  • Different materials such as polymers, wood, metals and composite materials can all be joined together
  • The process can be easily automated and doesn’t required skilled labor
  • No pre-treatment of harsh chemicals onto the material
  • The process is environmentally friendly
  • Does not produce fumes or flash
  • The process is easily repeatable for increased production rates
  • Mechanical strength of the material near the joint increases due to work-hardening
  • Additional fasteners/adhesives are no unnecessary

A Rivclinch® tool will provide you with throughput INCREASES, labor cost DECREASES, product cost DECREASES and assembly weight DECREASES. Wow!
