Overview

Foundry & Fabrication uses two techniques to make sand castings; the older greensand method that generally uses clay bonded sands, and the newer airset moulding method. For more than twenty years now, we have also been able to offer aluminium die casting through the gravity die casting method.

It is essential that the correct method of manufacture is selected to suit the requirements of a particular customer. Our moulders and gravity die casters have over 100 years of experience in bronze foundries and in making aluminium castings and we can help you select whether greensand casting, airset or gravity die casting would be the best method for you. We also carefully select the suppliers for all of our materials, whether this is high grade aluminium, sands or the special chemicals used in the processes.

Foundry & Fabrication use principally two methods of manufacture to produce aluminium castings in the foundry. Sand Casting and Gravity Die Casting. Both processes being fully accredited to ISO9000:2008.

Sand Casting

The sand casting process can be broken down into two forms of aluminium casting: Greensand casting and the more modern process of Airset casting. Both processes are fundamentally the same in so far as the elements used include sand and usually, a wooden pattern. Where the two sand casting methods differ is that the greensand casting process involves clay bonded sand whereas the Airset sand casting method uses special chemically bonded sand. Each process has its own advantages.

Gravity Die Casting

Gravity Die casting, contrasts with sand casting. As the name of the process suggests, it involves the weight of the molten aluminium – gravity - to fill a void within an iron mould to produce an aluminium casting,

It is essential that the correct method of manufacture is selected to suit the requirements of a particular customer. Our moulders and gravity die casters have over 100 years of experience in foundries and in making aluminium castings and we can help you select whether greensand casting, airset or gravity die casting would be the best method for you. Whether your project will involve sampling and prototyping, the average batch size of the aluminium castings and the finish will all be factors that the company will consider when assisting you to determine the correct process.
