How do I figure out how much ComposiMold mold making compound I need?
The critical information that you need to know for this calculation is the density of the ComposiMold. ComposiMold has a density of 1.2 grams per cubic centimeter or 0.69 ounces per cubic inch. In most cases approximately a 0.5 inch on the outside of your mold is good to provide mold support to your mold. Start by figuring out the size of your part. The easiest way to estimate is to take the length, width and height dimensions as an estimate in cubic centimeters or cubic inches. To this dimension, add an inch to each dimension and find the total area of your mold (Or use the volume of your container that you will be molding the part in) Subtract the part size from the container size and multiply by the density of the ComposiMold. This will give you the amount of ComposiMold you need. Here is an example from one interested customer: The part to be molded is 4.5 x 6 x 0.5 inches. I suggest about a 0.5 inch of ComposiMold around to provide support. So 5.5 x 7 x 1.5 inch container. 57.75 c
