Microwave heating apparatus especially useful for heating and curing reinforced thermo-hardenable synthetic resins is disclosed. Heating cells are formed by parallelepipedal enclosures, the walls of which are odd multiples of 1/4 the wavelength of electromagnetic energy being utilized for heating. Adjustment means for adjusting the enclosure to minimize reflected power are mounted within the enclosure. A production line comprises a series of successive heating cells that are supplied from the same power source; die structures between the cells can be used to form the material being processed.
