Our patented technology
plastics-metal stir welding

Plastics and metals are among the most crucial construction materials. Thanks to our patented technology, we now enable you to achieve an even simpler connection between these materials, all in a single process step. With low process forces and low temperatures, there is minimal measurable deformation. The use of recyclable plastics instead of aluminum contributes to environmental conservation!
