Perfect Adhesion Before Bonding and Painting
In modern manufacturing—automotive, electronics and consumer devices—reliable
surface activation is essential. Plastics and silicone components are difficult
to bond or paint unless the surface is clean, homogeneous and correctly
micro-structured.
Laser surface treatment provides a precise, contact-free and fully controlled
solution for preparing plastics, polymers and silicone parts before bonding,
painting or coating.
The laser selectively removes contamination such as
silicone oil
mold release agents
additive residues
organic film (fingerprints)
while modifying the surface microstructure at the same time. The process is non-abrasive—no scratches, no erosion, no risk of thermal damage thanks to controlled heat input.
Where laser surface activation delivers maximum value
A key advantage is laser surface activation, where the beam creates controlled micro-roughness that dramatically increases adhesion strength for adhesives, coatings and paints. This is indispensable for applications such as:
Bonding silicone components Traditionally very low adhesion
Painting automotive plastic parts
Coating sensor housings and enclosures
Bonding seals, gaskets and elastomers
Painting injection-molded components before assembly
Laser activation prevents cracking, peeling and paint failure caused by mechanical stress or long-term use. The result is dramatically improved product durability, lower scrap rates and a stable, repeatable production process.
