Adamstown Engineering Ltd is a family run operation
that has been in the foundry business for over 45 years. We have flexible manufacturing processes in which we can produce small or large runs. We can provide a level of expertise in Sand Casting and Die Casting.
Our family run business is large enough to service any requirement
But we are small enough to care. Metal Casting Process
Adamstown Engineering use 2 methods for manufacturing aluminum
Castings, Sand casting and Gravity Die casting. Sand Casting is the more traditional method for casting aluminum
We use 2 types Greensand and Airset sand casting. Greensand Casting is the oldest and least expensive . Green sand is known principally because of the moisture content within the sand. Clay and chemical additives are added to the sand to act as binders which results in a compound that is suitable for the sand moulding process. The sand mixture is compressed around the pattern taking on the shape of the casting. Sand cores are used to form passageways in the casting. The two halves of the mould are closed and aluminum is poured into the cavity and left to solidify. After Solidification has taken place the sand is vibrated until it is released from the casting. The green sand casting process is suitable for small to medium size batches. The initial tooling costs are generally low and involve the production of usually a wooden pattern. Airset Casting process is used for extremely large Castings. It produces a sand mould of considerable strength which can be free standing without the need for moulding boxes and therefore unlimited in size. The process involves mixing sand, resin and a chemical hardener together. The sand mixture is then compressed around the pattern and left to set.
