| A customer sends a CAD file for the part to be molded to the system. The system assesses the CAD file to determine various pieces of mold manufacturing information. One or more acceptability criteria are applied to the part, such as whether the part can be manufactured in a two-piece, straight-pull mold, and whether the mold can by CNC machined out of aluminum. If not, the system sends a file to the customer graphically indicating which portions of the part need modification to be manufacturable. The system provides the customer with a quotation form, that allows the customer to select several parameters, such as number of cavities, surface finish and material, which are independent of the shape of the part. The quotation module then provides the customer with the cost to manufacture the mold or a number of parts. Budget-driven quotation is possible, wherein proposed modifications in the molding process are controlled by the budget of the customer. Interactivity is also achieved, with the customer being able to modify the quotation interactively by modifying one or more of the initially selected parameters, including selecting a different budgeted amount. | ||||||
