There is a need to join metals and plastics together in numerous lightweight structures. Engineers from Fraunhofer LBF, Fraunhofer ILT, Siegfried Hofmann and Weber Fibertech structure the surfaces of metallic joining partners before the molten mass envelopes them as inlays in the molding process.

Cost-efficient Laser Processing

Using hybrid materials from dissimilar material combinations is gaining popularity in safety-relevant and functional components. Glass fiber-reinforced polyamides and high-alloy steel and aluminum materials are used particularly in highly stressed component areas in the automotive industry. With conventional joining technologies for connecting metal and plastic parts (e.g. bolting, riveting, welding or gluing one is bound to run into technical and economic constraints.

Laser technology is key from the technical and economic perspective when it comes to large-scale production. Lasering allows contact-free processing with high process speeds and abundant design...
