BONDING PRE-TREATMENT OF METALS

BONDING PRE-TREATMENT OF METALS

Adhesive joining is one of the most demanding joining technologies in the industry today. In addition to the qualified selection of suitable adhesives, cleaning and pre-treatment must also be carefully defined in order to ensure reproducible and process-reliable adhesion over the long term.

By removing oxide layers, the surfaces are cleaned in a way that is suitable for adhesive bonding.

In addition, the parameters used especially in the cleanLASER process for processing light metals (especially aluminum and magnesium) in a single process step not only lead to cleaning, but also to modification of the component surface.

This makes it possible to achieve extremely high corrosion stability and thus a long-term adhesive pre-treatment.

The roughness of the surface can be specifically adjusted for high and low viscosity adhesives.

ADHESIVE PRE-TREATMENT OF CONTROL UNITS

Secure and corrosion-resistant sealing.

Pre-treat on-board chargers and control units for both FIPG and CIPG seals with cleanLASER.

The laser beam cleans and modifies the sealing surfaces so that even after 40 days of storage in a salt spray mist no corrosive infiltration and thus no leakage of the housing occurs.

The electronics are thus safely and permanently protected from moisture.

ADVANTAGES

Optimal conditioning of metallic surfaces for adhesive preparation

Significantly increased corrosion resistance of light metals

Aging resistant bonding

Dry, media-free pre-treatment method

Dry, media-free pre-treatment method

Seamless process monitoring options thanks to optional cleanLASER sensor technology
