Abstract
With a device for heating parts,made of a microwave absorbing plastic and having a microwave generator,that generates microwaves of a certain wavelength, an antenna,to which the microwaves are conducted, having at least one free end,and a device,which surrounds the antenna,, it is proposed that the device for shielding,be designed with a tubular shape, so that the device,has an inside diameter smaller than half the wavelength, projects beyond the free end,of the antenna and has an opening,in its end face. With this device it is possible to achieve a spatially limited and nevertheless homogeneous heating of parts,. Furthermore a method of heating or welding, shaping or crosslinking parts made of a microwave absorbing plastic using this device is also proposed.
