The Assembly Molding cost model supports the molding of thermoplastic materials, and assumes that the material is delivered in pellet form. The model relies on the same material properties as the Plastic Molding process group--see Materials for Plastic Molding.

With Assembly Molding, as with the Assembly process group, you cannot access the Material Selection dialog from the Manufacturing Process pane. Once GCDs have been extracted from the CAD model, you can access the Material Selection dialog from the Production Scenario tab of the Cost Guide (click … in the Material: field):

The default material for Assembly Molding is ABS.

The material you select specifies the material for all the molded Subcomponents. For more information, see Materials for Plastic Molding. See also Material Cost in Insert Injection Molding Formulas.
