A series system for large welding parts, and an integration head with slim dimensions: LPKF Laser & Electronics AG showcases state-of-the-art technology for laser plastic welding.
 
The LPKF booth will be showcasing new developments of the TwinWeld hybrid welding system. A new high-performance welding head and a compact housing are the stand out features of the new series. In hybrid welding, the laser beam is surrounded by a thermal field. This enlarges the process window, increases the welding speed, and no longer needs to be followed by a tempering process. “Instead of complex clamping tools, this method requires only the use of an inexpensive component holder. In addition, an integrated rotary indexing table supports two stations; a loading/unloading station and a welding station – of large car lights for instance,” explains Frank Brunnecker, Vice President Business Unit LaserWelding at LPKF Laser & Electronics AG.

In the redesigned inline module “LPKF LQ-Integration” the development engineers succeeded in significantly reducing the dimensions of the welding head. One or more heads can be installed in space-saving positions in the customer’s own layout. The laser source and the controls are installed independent of the heads in a separate cabinet.

In addition to these innovations, LPKF will also be showing two more systems:
The LPKF LQ-Vario RT has a low-maintenance laser source and a rotary indexing table. An optional double clamping device is a low cost addition which delivers even higher part output.

Laser staking with the LPKF LQ-Spot involves welding a laser-transparent rivet head on a housing dome. The rivet head can be used to fix any kind of component – even printed circuit boards. The rivet head does not melt into the tool zone during laser staking.
