RIVCLINCH®

 RIVCLINCH® METHOD:

Clinching is a method of joining metal sheets or profiles by cold forming the material without joining elements to form a form-fitting, non-positive connection. Two-layer or multilayer joints are possible.

Due to its special characteristics, RIVCLINCH® joining technology is used primarily in air duct construction, door and gate manufacture, for white and brown goods, in air conditioning and energy technology and in the sheet metal-working industry.

PROCESS

During clinching, the materials to be joined are first drawn into the die by the punch.As soon as the lower material touches the anvil, it starts to flow to the sides.The movable die segments are moved outwards. The flowing action of the materials forms the button. The punch then moves back to the starting position, the joined part can be removed, and the side parts of the die are closed up again by a spring.The localized deformation of the material produces a form-fitting, non-positive connection.

BENEFITS

  • No additional fasteners

  • Protects the surface of coated components

  • Reproducible

  • Environmentally friendly
