LUFT-WENT

LUFT-WENT is involved in the production of ventilation systems as well as air conditioning and recuperation equipment. In this industry, creating tight connections is crucial. The connections are structural, so they need to be adequately durable. Fast assembly is also very important.

The joining technology used by LUFT-WENT needs to meet all these conditions.

Initially, LUFT-WENT’s basic technology for joining sheets was resistance welding. However, it is an energy-intensive process. During resistance welding, the zinc coating is damaged, fumes harmful to health are given off and the welded elements are susceptible to corrosion. In order to protect against corrosion, the welded components also need to be galvanized.

Replacing the stationary resistance welding machine with the RIVCLINCH® 0404 IP V3 AERO had a positive impact on production at LUFT-WENT. Two people used to be required to install the large ventilation ducts, while only one operator is required to operate the hand-held clincher. The device can be connected to various workstations that have a compressed air connection. Clinching eliminates the need for additional protection of the welded component against corrosion because it does not affect the zinc coating of the sheet. There are no high temperatures or emission of harmful elements during assembly. Operating of RIVCLINCH® devices is easy, and no special permissions are needed by the operator. The joints used in ventilation obtained by clinching have the appropriate class of tightness, and assembly is fast.
