We have the facilities and the capabilities to produce aluminum castings for a wide variety of industries, including High Horsepower Diesel Engines, Defense, Gas Turbines, Machine Tools, Compressors, Pumps, Valves, Medical Equipment, Light Construction Equipment, Articulated Trucks, Photo Imaging and Printing.

Aluminum castings have many benefits when compared to the likes of steel or grey iron castings. It produces strong, corrosion-resistant castings with high electrical and thermal conductivity. Aluminum castings are comparatively lightweight, which results in lower storage and transportation costs. They are easy to machine and easy to recycle. Finally, aluminum is a tension free metal, which gives almost unlimited freedom in the shape and size of castings you can create.

Heat Treatment can further enhance their mechanical properties with maximum properties being achieved through a full heat treatment cycle of solution treatment, followed by a quench, and natural or artificial ageing.

Aluminum Sand Casting

Traditionally, aluminum casting was achieved using a process called green sand casting. This involved the use of wet sand in the creation of casting molds. As a method, it was efficient and cost-effective, but not without its drawbacks.

During the early 1990s, Harrison Castings moved from the traditional green sand aluminum casting technique in favour of a process known as air set casting. This involves the use of a fast curing adhesive resin to create strong sand molds. This technique is very versatile, as it technically places no limits on the size of the castings that can be created. This process is also chosen for castings of complex shape requiring intricate cores or for large castings.

Aluminum Gravity Die Casting

The die casting method of aluminum casting is ideal when large numbers of simple or complex castings are required. This casting process results in an aluminum casting with smoother surfaces and good dimensional accuracy. This means that less fettling and finishing is required.

At Harrison Castings, we are able to offer customers with a high quality aluminum gravity die casting service.
