Cost Algorithms and Calculations

Total injection molding costs aggregate the costs of material, labor, equipment, and tooling. Typically, tooling accounts for a significant portion of the total cost. The part’s wall thickness and material (because they affect cooling time) have a significant impact on both labor and tooling costs.

This section details how costs are calculated by aPriori. Note that you can override the calculation of some of the quantities involved, and specify them explicitly—see Additional User Inputs, below.

When not otherwise specified, costs are per part.

This section is organized into the following cost categories:

 Primary Direct Costs

 Other Direct Costs

 Material Utilization

 Times

 Nominal Wall Thickness

 Required Clamp Force

 Number of Mold Cavities

 Mold Dimensions

 Tooling Cost
