Better than welding and adhesive bonding: sculpture-bonding via "METALANGELO"

The exhibit will be displayed at the CAU booth C07 in hall 2 for the whole fair week. On Tuesday, April 24, Prof. Rainer Adelung will present the polytitanium project at 2:00 pm and 4:00 pm at the CAU booth.


Metal injection moulding is a pioneering additive manufacturing technology with which titanium parts can be produced very flexibly. Using joining technology, the connections between metals and/or plastics should achieve "perfect" adhesion, and therefore should only be separated by a cohesive fracture. At the same time, the procedure should be carried out quickly and flexibly. "Nanoscale sculpturing” is such a procedure. It can be easily used anywhere - even instead of welding - and allows metals to be joined to any plastics. The mobile prototype “METALANGELO”, which is the same size as a welding device, can rapidly “sculpture” aluminium surfaces at room temperature with nanometre precision, so that they can be perfectly bonded with various plastics (also silicones) or metals (including copper).

The polytitanium project pursues the combination of these two technologies, "nanoscale sculpturing" and metal injection moulding. These innovative processes will be demonstrated using a series of exhibits, showcasing different metal and plastic material combinations.
