وصف المنتج
We specialize in very complex, close tolerance aluminum sand castings. Primary alloys include aluminum silicon (300 series) and aluminum-magnesium (500 series). All electric melting. Four hunter automatic, Green Sand Molding lines are used for high to medium volume parts from ounces to 50 pounds. Low volume and prototypes castings up to 40 pounds are produced on our Airset/Nobake molding line. We also are capable of providing prototype castings.
What Is Sand Casting?
Sand casting is an efficient metal casting process in which sand is used as the mould material. Over 70% of the world`s metal castings are produced via the sand casting process, and Harrison Castings have the largest sand casting foundry in the UK.
The two most common types of aluminium sand castings processes are Green Sand Casting and the Air Set Casting method. We moved away from the traditional Green Sand moulding method in the early 1990s in favour of Air Set moulding
Why Use Sand Casting Over Other Casting Methods?
Casting in sand is a highly efficient and cost-effective process because up to 80% of the moulding sand we used is reclaimed and reused. This streamlines our manufacturing process whilst greatly reducing the cost and amount of waste produced.
The sheer strength of the moulds created means that a much greater weight of metal can be used, allowing for the casting of complex components that might otherwise have been fabricated from individual parts.
Moulds can be created for a lower initial setup cost compared to aluminium gravity die casting and other casting methods.
