Aluminum casting refers to the casting process using aluminum alloys. Casting is the original and most widely used method of forming aluminum into products. Technical advances have been made, but the principle remains the same: Molten aluminum is poured into a mold to duplicate a desired pattern.

 

Aluminum alloy casting process performance

The performance of aluminum alloy casting is generally understood as the synthesis of those performances that are most prominent in the process of casting, crystallization and cooling. Liquidity, shrinkage, air tightness, casting stress, inhalation. The properties of aluminum alloy are dependent on the composition of the alloy, but it is also related to casting factors, heating temperature of alloy, complexity of casting type, pouring gate system and shape of gate.

 

High Pressure Aluminum Die Casting

High pressure aluminum die casting is a manufacturing process in which molten metal (aluminum) is injected with a die casting machine under force using high pressure into a steel mold or die to form products. Precisely formed aluminum parts requiring a minimum of machining and finishing can be produced through this casting method. High pressure aluminum die casting is mainly used for thin wall thickness aluminum products with high volume production.

 

Low Pressure Aluminum Die Casting

In the low pressure die casting process the metal is transferred from an air tight furnace through a rising tube into a metallic tool. The casting temperature is about 750°C.

Low pressure aluminum die casting is competitive casting method when the production quantity is relatively small and/or when heat treatment is needed to improve the mechanical properties. The tolerances and the surface finish are the same as achieved by gravity die casting. The tooling costs are somewhat higher than by sand casting. For its low pressure, this manufacturing process is more suitable for thick aluminum products, even small volume is feasible.
