Aluminium Casting Cost Formula
The following formulas are used to estimate aluminium casting cost per casting (using a simple material-plus-tooling model):
\text{Cost per casting}=W\cdot P\cdot C+\frac{M}{F}\\
W=\frac{V\cdot \rho}{1000}Variables:
- Cost is the estimated cost per casting (in your chosen currency)
- W is the casting weight (kg)
- P is the aluminium price per kilogram (currency/kg)
- C is a dimensionless cost multiplier (e.g., 1.0 for material-only; 1.3 adds 30% for overhead/labor, etc.)
- M is the mold/tooling cost (currency)
- F is the number of castings produced from the mold (castings)
- V is the casting volume (cm³), used only to estimate weight
- ρ is the alloy density (g/cm³)
To estimate cost per casting: calculate material cost (W × P), apply the cost multiplier (× C), then add the allocated mold/tooling cost per casting (M ÷ F). If you do not know weight, you can estimate it from volume using W = (V × ρ) ÷ 1000 (because cm³ × g/cm³ = g, and 1000 g = 1 kg).
What Is Aluminium Casting Cost?
Aluminium casting cost refers to the money spent to produce aluminium parts by pouring molten aluminium into a mold and allowing it to cool and solidify. Costs can include raw aluminium, melting and casting energy, labor, scrap and yield loss, tooling/pattern costs (often amortized across the number of parts), equipment maintenance, and quality control. Design complexity, part size/weight, and production quantity can significantly affect the final cost.
