History

In 1926 John McKelvey Snr. entered the foundry business. During his lifetime he acquired Bankstown Foundry which he operated successfully until his death in 1972. In 1981, Ajax Foundry was purchased by John and Peter McKelvey. Today, their sons Anthony and Peter McKelvey continue in that proud family tradition through the development and expansion of Ajax Foundry.

 

Ajax Foundry employs some 35 people in the manufacturing and marketing of quality, price competitive ferrous castings. We manufacture a wide range of cast products including Cast Irons, Ductile Iron and Austempered Ductile Iron. We also provide our own patternmaking, machining and drilling to individual customers requirements.
