Other Direct Costs for Plastic Molding
Additional direct costs and are calculated using the formulas below.
Additional Direct Costs = Colorant Cost x Part Rough Mass
Additional direct costs are the product of the following:
• Colorant cost (default rate of 0, user-specified rate, or standard rate—see
User Inputs for Plastic Molding)
Total Setup Cost Per Part = Setup Cost Per Part + Startup Scrap Cost Per Part
Total setup cost per part is the product of the following:
• Setup cost per part (see formula below)
• Startup scrap cost per part (see formula below)
Setup Cost Per Part = (Batch Setup Time / Batch Size) x (Labor Rate + Overhead Rate)
Setup cost per part is a function of the following
• Batch setup time (see
Times for Plastic Molding below)
• Batch size (specified in the Production Info dialog)
• Labor rate
• Overhead rate
Startup Scrap Cost Per Part =
(Sum of Per Part Material, Labor, and Overhead Cost) * Number of Scrap Parts
Startup scrap cost per part is a function of the following:
• Per part material cost
• Overhead cost
• Number of scrap parts (see formula below)
Number of Scrap Parts = Default Scrap Time / Cycle Time
Number of scrap parts is the quotient of the following:
• Default scrap time (specified in a plant variable, scrapTimeInMinutes_IM/RIM/SFM)
• Cycle time (see
Times for Plastic Molding below)
Total Production Volume = Part Annual Volume x Part Production Life
Total production volume is the product of the following:
• Part annual volume (specified in the Production Info dialog)
• Part production life volume (specified in the Production Info dialog)
Foam Cost Per Part = Part Finish Mass * Foam Cost Per Part Mass (RFM only)
For RFM, the cost of foam per part is based on the total mass of the part (including foam) and the cost per percentage of the total mass of the part attributed to foam:
• Foam Cost Per Part Mass (see
SFM Material Utilization)
