Aluminum Die Castings

Manufacturer: Paber Aluminum

Process Description

The aluminum casting process consists of two processes: sand casting & permanent mold casting.  Both processes utilize garvity poured molten aluminum, which provides superior strength to die casting.  Sand casting utilizes green sand, or resin "no bake" sand, to provide the mold impression.  As molten aluminum is pored, the sand allows air to permeate through it as the metal fills the mold.  This process is ideal for parts weighing up to 2,000 pounds.  Permanent mold is suited for smaller, higher volume parts.  Since the molds are made from machined cast iron as opposed to sand, the cycle time is reduced, and tighter tolerances and a superior finish are achieved. 

Alloys:  206, 319, 356, 413, 535 and 713 (Alloys in bold can be used in permanent mold).
Sand:  The sand quality is controlled by an internal laboratory which insures the humidity, permeability and compactness specification compliance.
Cores:  Cores are used in complex casting.  Three types of cores can be made: CO2, Shell Core and Resin Sand Core.
X-ray Inspections:  Paber has the largest real time X-ray machine in North America - parts up to 8 feet x 6 feet and up to 5" thick.
Machining:  5 axis CNC milling up to 110" x 134" x 63", CNC turning.
Finish:  In house heat treat, outsourced finishes include chemical conversion, anodize, e-coat, impregnation, plasma coating.
