“…Other injection bonding processes with classic 2C adhesive systems have already been tested on several occasions [6]. With open times of over 10 min and an almost constant in-process viscosity, rheology plays a minor role and these processes are a lot easier to handle [14]. With open times of 5 s, the viscosity increases steeply from the moment the components come into contact.…”

“…This calls for an intelligent tool concept for forming the mold and the associated play with the force of gravity and the flow paths of the PUR material [5]. Two other injection bonding processes in the automotive industry use adhesives with a higher viscosity and fill the gap with pressure [6,7]. Due to the higher viscosity the adhesive doesn't flow away by the force of gravity, but it also needs at least 10 min of curing to reach handling strength.…”

With regard to the joining of large structural components in particular, joining technology is becoming increasingly important. The weighting of the cycle time, the associated costs and the influence of component tolerances pose special challenges for classic joining technologies. Although classic adhesive bonding processes can join different materials while also compensating for tolerances and different coefficients of thermal expansion, they always involve design limitations for the joining process and long curing times. For classic 2C PUR adhesives the curing times reach from 10 min up to several
