The following list describes the available specification choices in this tab; for more details on how these are implemented, see Blow Molding: Modeling Calculations.
•Machining Cost Options...
The machining cost is either specified by the user or calculated by the program (the default option) based on the machining difficulty.
•Mold Replacement Cost Options...
The cost for the periodic replacement of molds (usually, every 2-5 years) can be considered as a consumable cost or ignored. The replacement frequency can be specified either in operating years or number of cycles (also known as shots).
•First Mold Set Expense Options...
The expense for the first mold set can be considered a capital expense and depreciated. By default this does not happen.
