Pattern Making and Foundry work

Many parts for wind and water mills are metal castings. Whether it is an iron cross to which the sails are bolted or a simple bronze bearing the casting is made in the same way.

Using a pattern a mould is created in sand and then the molten metal is poured into the mould.  Careful thought is required to produce the pattern in the first place to ensure the item can be moulded and that the metal will flow into all of the parts of the mould.  When the casting has been made it will require finishing to machine the rough parts of the casting to a smooth surface.  

The quality of the casting is as important as the pattern making. If the casting contains too many blow holes or other imperfections then it may not be possible to machine it properly.

We can offer castings in cast iron, 'sg' iron, steel, bronze and brass
