Vibration welding with hot air preheating is a further development of the conventional vibration welding process. The preplasticising of the two surfaces of the joint results in a minimisation of abrasion, and hence in a minimised residual soiling content. Preheating with hot air reduces the production costs, as by contrast with hot gas welding, no processing costs for the inert gas are incurred.
Materials:
All thermoplastics can be vibration welded (e.g. PE, PP, PA, PPA, POM), with the exception of soft plastics that do not have the necessary structural strength and therefore tend to vibrate with the welding head.
