Die Casting - Aluminum, Zinc and Magnesium

Die Casting

Die casting is a process of forcing molten metal under high pressure into a mold cavity. The mold cavity is the shape of the desired part. Most die castings are aluminum, magnesium, or zinc. Depending on the type of metal being cast, a hot or cold chamber machine is used.

The metal dies can be expensive, which tends to limit the process to higher volume production. Die casting is well suited for small to medium size parts. Die castings are characterized by a very good surface finish and dimensional consistency.

Tanfel offers clients a variety of finishing process options for casted parts.

Aluminum Alloys:

Relatively lightweight (270% lighter than zinc)
High resistance to corrosion
Good mechanical properties
Good dimensional stability

Zinc Alloys:

Considered as the easiest to cast
Longer tool life due to lower temperatures and pressures
Ability to be produced in thin wall thicknesses and tighter tolerances
Good for plating and coating

Magnesium Alloys:

Lightest weight among commonly used structural metal (50%) lighter than aluminum
High strength to weight ratio
Excellent damping ability
EMI shielding ability
