Microwave curing

Image Number 6 for United States Patent #5222543.

An apparatus for centrifugal casting of hollow articles in particular pipes. The apparatus has an elongate generally cylindrical hollow mould with a center conductor extending along the longitudinal axis so that the combination acts as a coaxial waveguide. A microwave source and waveguide system are provided to direct substantially TEM mode radiation into one end of the mould. The mould and center conductor are terminated at the other end by a short circuit to microwave radiation so that standing waves are established in the mould. The invention also provides a method for centrifugal casting of such articles in which a casting composition is placed in a hollow rotating mould and microwave radiation is directed into the mould to heat the casting composition.
