- According to the weight of the parts proposed in the design, plus the weight of the machining allowance.
- Weigh the weight of the investment mold, and then obtain it as follows:
Casting weight = investment weight * A, A = casting material density / mold material density. - List the shape and size of each part of the investment mold or casting, obtain its volume, and then multiply the total volume of the casting by the density of the alloy to obtain the mass of the casting.
