A device for molding products made of glass or a synthetic resin which device has a microwave generator, a microwave oven coupled to the generator and mold parts movable relative to each other provided in the microwave oven for forming molds for holding a parison of the glass or synthetic resin to be heated dielectrically.

Molding device comprising microwave generator and a microwave oven

A method and a device for moulding products made of glass or synthetic resin is provided, whereby a parison of material (3) is heated by microwave heating up to a predetermined temperature and is then moulded into the desired product shape by moulds (5, 7). The method and device are particularly suitable for manufacturing optical products such as lenses, prisms, and gratings.

Method of moulding products with heating a parison with microwaves

In the internal coating of a tube of an electrically insulating material by a second electrically insulating material by reactive deposition of the second electrically insulating material from a gas mixture which is passed through the tube, the desposition is activated by a plasma which is produced by microwaves and is reciprocated in the tube. A method with low energy consumption and a device of a simple construction are made possible in that the plasma is excited by TE 011 resonance in a cylindrical resonator.
