Duncan Propellers

Duncan Propellers Limited

Bronze Foundry

Very high quality castings

The foundry is equipped with new electric induction melting furnaces for cleaner and purer castings.

They consist of two drop down furnaces of 100kg and 250kg capacity and one tilting furnace of 1 ton capacity.

The bronze materials used for propeller castings are from certified virgin ingot and the quality of the melt is carefully controlled.

The propeller casting method has been developed over a number of years to ensure a high level of cast quality.

Stern-gear castings such as rudders, shaft-brackets and shaft-bearing housings are also produced.

The foundry is equipped with a recirculating sand system and a mould-handling track system for improved productivity and smooth handling.

Castings up to 1000kgs or 1 ton in weight can be produced.
