CUPOLA FURNACES
The foundry has four cupola furnaces which produce cast iron items such as coal screws, chain driving sprockets and cro-iron grinding ballswith up to 1.5% chromium. In fact, four cupola furnaces give Craster International the capacity to produce the largest single cast iron product in Zimbabwe – the 24 tonne sugar roll. No other foundry in Zimbabwe has such a capacity.

ELECTRIC ARC FURNACES
Craster has three electric arc furnaces. These produce cast iron, cast products such as stainless steel, manganese nickel chrome, ni-hard and most importantly all grades of grinding balls. The 4 cupola furnaces combined with the 3 electric arc furnaces give Craster International.

400kg INDUCTION FURNACES
The importance of these two furnaces is that they facilitate the manufacture of castings in small economic quantities. Furthermore the magnetically heated furnace enables uniformity of the metal bath, which results in superior cast products

PUSH-UP FURNACE
All non-ferrous metal castings such as brass, bronze and copper are produced in this furnace. Although most of the work done here is for internal use, Craster has the capacity to produce ornamental as well as functional but prestigious items such as name plaques, lettering, numbering and door handles.

SPIN CAST MACHINE
Craster is one of the few companies in Southern Africa capable of undertaking centrifugal or spin casting. This is a special method of casting used for producing items such as cast iron pipes and sleeves.
