Hot gas implant welding of polypropylene via a three-dimensional porous copper implant

There is an increasing need for joining technologies of thermoplastics, in which hot gas welding is one of the most promising methods. In this paper, an innovative hot gas implant welding technology was used for the bonding of polypropylene (PP). The hot gas implant welding of PP plates was conducted under different heating time (th) in this research, while porous copper was selected as heat transfer implant. The evolution of temperature with th...
