Material Options for Die Casting

Different metals cost different, weights different and performs different, according to the different budges, different requirement and function, the material choice can detail into the follow:

Aluminum alloys including A380, A413, ADC10 and ADC12 are ideal strong, lightweight for complex designs, it can be high polish and texture in mold, and can apply the finish such as painting and powder coating.

Zinc alloys including the Zamak 3 and Zamak 5 are less expensive, it is ideal used for mechanical core parts and it preforms amazing mechanical properties,Zinc Alloy is good in casting status and effects great in plating finish.

Magnesium alloys including AZ31B and AZ91D are the less weight but high performance material, its is apply in applications in the Aerospace and Defence industrial. But it is a flammable and explosive material during casting.

Metal Die casting process:

The quality and precision of the die casting part is depend on the quality of the die casting tooling, after the prototype confirmed and starts the die casting production,
we will:

  • Review and adjust the 3D file suit to the die casting process .
  • Verify the tooling material according to the quantity demanded .
  • provide the FDM for customer confirmed .
  • using old multi-axis CNC machine for the tooling making .
  • Mold test and get T1 production for client confirm .
  • final production with fine finish treatment.
