A method for the non-contact bending of parts made of a plastic material having thermoplastic properties and according to this method, bent or adjustable part

摘要

A method for the contactless bending of parts (t) of a plastic material having thermoplastic properties by means of local melting with the aid of an energy beam (it) and subsequent cooling, wherein a strongly convergent energy beam (it) is used, which the focal point (fp) on or in the vicinity of the energy beam (it) the upper side (o) of the parts (t), and wherein the plastic by heat of absorption is locally melted in such a way that the parts (t) during cooling to the energy beam (it) bent towards.
