THE ‘PMJOIN’ PROJECT EXPLORES WAYS OF CREATING METAL-PLASTIC JOINTS WITH LASER
Erum group is closely following the progress made in studies as part of the PMjoin European Project, participating in a consortium of companies that work mainly in the vehicle manufacturing sector and researchers from centres in France, Germany, Belgium and Spain.
The PMjoin project is developing an innovative process for joining plastic and metal using laser welding, which eliminates the need for additional materials, adhesives and other joining elements and obviates a large number of steps in the production process.
The market trend for lighter, less contaminating vehicles is leading the automotive section to make parts with fewer mechanical requirements with polymers. However, many of these parts have essential metal components, deriving from the use of multicomponent materials.
The project is developing a new joining concept using lasers without direct contact to create a stable, robust joint from both a physical and mechanical point of view.
The resulting joint guarantees structural integrity and makes for more streamlined, flexible industrial processes when compared to mechanical joints. It also has far lower environmental impact.
