With laserTREAT®, the metal surface is prepared using laser remote structuring (LRS). This creates a defined microstructure that enhances bonding strength and ensures long-term stability. An integrated cleaning system guarantees optimal surface conditions before joining.

The plastic and metal components are precisely positioned in the varioJOIN® or giroJOIN® systems using dedicated part holders and joining tools. Secure fixation ensures reproducibility and allows flexible handling, either manually or fully automated with robotic systems.

At the heart of the process is the coreJOIN® module in combination with coreSUPPLY® units. The inductor embedded in the joining die generates a concentrated electromagnetic field, inducing eddy currents in the metal. The metal heats rapidly and locally, softening the plastic at the interface. Controlled pressing ensures intimate contact and reliable bonding.

After passive cooling, the result is a solid metal-plastic hybrid joint – strong, media-tight, and fully recyclable. The joined component can be directly removed from the system or passed on within a fully automated line such as atroJOIN®, enabling efficient series production.
