Bollhoff's acclaimed RIVCLINCH process for fastening sheet metal and aluminum is said to be the only such joining system for ducting that has gained coveted TUV approval.

The TUV Type D air tightness Certification covering “Duct connections for sheet metal air ducts with rectangular sections” assures users of an air and gas tight seal in all H&V applications .

Capable of joining up to 3 layers of sheet metal with a combined thickness of up to 3.5mm, the RIVCLINCH process is also a joining method that doesn’t involve the drilling or punching of any holes in the material, rendering it ideal for use with pre-coated or pre-painted sheet. Typical joining cycle times vary between 0.5/sec and 0.9sec dependent upon material thickness so the process is swift too.

The RIVCLINCH tooling has been configured for use by companies large and small and to this end can be specified in a wide range of configurations from hand-held tools weighing less than 6kg in gyroscopic suspension for low volume work right up to fully automated PLC controlled bespoke systems with multiple joining heads for high-throughput, heavier duty projects.
