• Mass Waste: Mass waste is the mass of that portion of the pouring volume contained in the feeder system (runners, risers, etc.). By default, it is calculated as described in Material Cost and Utilization for Die Casting (see the formula Mass Waste). You can override the default by entering a value in kilograms. Note that the override affects only taxonomy calculations, and has no effect on machine selection.

• Mass Loss: Mass loss is the pouring mass per part of metal that is oxidized or spilled during melting and cannot be re-melted. By default, it is calculated as described in Material Cost and Utilization for Die Casting (see the formula Mass Loss). You can override the default by entering a value in kilograms. Note that the override affects only taxonomy calculations, and has no effect on machine selection.

• Metal Additive Type: This PSO allows you to select from among the additive types specified in the lookup table tblMetalAdditives. The default additive type is named Default in the lookup table.

• Metal Additive Rate: This PSO allows you to enter the additive cost per unit mass. The default additive rate is looked up by additive type in the lookup table tblMetalAdditives. The default additive type is named Default in the lookup table, with a rate of $0.22 per kg in starting point VPEs. See also the PSO Metal Additive Type.

• Material Remelt Allowance Percentage: This PSO allows you enter the fraction of waste that can be remelted. See Material Cost and Utilization for Die Casting. By default this is specified by the cost model variable defaultRemeltAllowancePM (1 in starting point VPEs).
