Required Shot Size

Required shot size affects machine selection (see Machine Feasibility and Selection). It is calculated with the following formula:

Required Shot Size = (Shot Size Safety Factor * Part Volume * Number of Mold Cavities *

Polystyrene Density) / 1000000

Required shot size is the product of the following:

• Shot size safety factor (specified by the cost model variable shotSizeSafetyFactor)

• Part volume (obtained from required PSO—see Part Volume)

• Number of cavities (see Number of Mold Cavities)

• Polystyrene density (specified by the cost model variable densityPolystyreneForShotSize)
