How to Calculate Casting Weight

Casting involves pouring a liquid into a mold with a hollow cavity. The liquid solidifies, forming a cast object of the desired dimensions. The mold is removed, allowing the object to be used in industry or other applications. Casting is often used to make complex shapes that would take too much time using other methods. You can calculate the weight of the liquid required for casting by multiplying the volume of the object being made by the density of the casting material.

Instructions

    • 1

      Determine the shape or combination of shapes that most closely resemble the desired mold. If you are casting a model house, the main part of the house would be a cube and the roof would be a pyramid.

    • 2

      Use the measuring tape to determine the dimensions of the shapes.

    • 3

      Calculate the volume of each shape in cubic inches. For the house example, you would determine the volume of the main part of the structure by multiplying its length by the width by the height. The volume of the roof would be determined by the formula: Volume of the pyramid = 1/3 x base length x base width x height.

    • 4

      Add the volumes of the individual shapes that combine to make the desired mold.

    • 5

      Find the density of the casting material in cubic inches. The density of iron, a common casting material, is 0.26 pound per cubic inch. The density of iron is 0.29 pound per cubic inch, while concrete is 2.3 pounds per cubic inch.

    • 6

      Multiply the total volume of the mold by the density of 1 cubic inch of the casting material.
