Microwave heating technology is a cost-effective alternative way for heating and curingudof used in polymer processing of various alternate materials. The work presented in this paperudaddresses the attempts made by the authors to study the glass transition temperature and curing ofudmaterials such as casting resins R2512, R2515 and laminating resin GPR 2516 in combination withudtwo hardeners ADH 2403 and ADH 2409. The magnetron microwave generator used in thisudresearch is operating at a frequency of 2.45 GHz with a hollow rectangular waveguide. During thisudinvestigation it has been noted that microwave heated mould materials resulted with higher glassudtransition temperatures and better microstructure. It also noted that Microwave curing resulted in audshorter curing time to reach the maximum percentage cure. From this study it can be concluded thatudmicrowave technology can be efficiently and effectively used to cure new generation alternateudpolymer materials for manufacture of injection moulds in a rapid and efficient manner. Microwaveudcuring resulted in a shorter curing time to reach the maximum percentage cure.
