Abstract: Aim of this work is to carry on joining of thermoplastic components in order to extend its results, in the future, to semi-manufactured components obtained through injection moulding processes. Although this technology has remarkable advantage as productivity, automation and cheapness, doesn’t allow to produce hollow components all at once. For this reason it is necessary to add a successive joining process. The most common technologies now used to join plastic materials shows that the Hot Plate Welding process is characterized by advantages as mechanical strength, freedom in design, cheapness, etc. On the other hand Laser Welding shows remarkable advantage as process speed, aesthetic quality, mechanical strength, versatility, minimum and local transfer of energy and absence of contact. Through Hot Plate welding the author carried out samples welded in different configurations changing process parameters like temperature and time of interaction. The characterization of the joining ha...
