Automated quoting of molds and molded parts
Automated, custom mold manufacture for a part begins by creating and storing a collection of information of standard tool geometries and surface profiles machinable by each of the standard tool geometries. 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 manufacturability. 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 an independent of the shape of the part.
1. A method of custom quotation for manufacture of a mold and/or manufacture of a molded part, the mold defining a cavity corresponding in shape to the part to be molded, the method comprising:
assessing a customer's CAD file via computer to determine at least one cost-affecting parameter of mold manufacture and/or part manufacture, the CAD file defining a shape of a part to be molded;
providing the customer with at least one computer menu of customer-selectable values for a cost-affecting parameter of mold manufacture and/or part manufacture unassociated with part surface profile;
allowing the customer to select one of the provided customer-selectable values;
computer calculating a quotation for mold manufacture and/or part manufacture based in part upon the cost-affecting parameter determined by computer assessment of the customer's CAD file and based in part upon the customer-selected value; and
communicating the computer calculated quotation to the customer via computer.
2. The method of claim 1 , wherein the cost-affecting parameter is a parameter of forming a cavity in an injection mold.
3. The method of claim 2 , wherein the cost-affecting parameter is a parameter of forming a cavity in an aluminum-based injection mold block.
4. The method of claim 3 , wherein the cost-affecting parameter is a machining cost estimate of machining a cavity in an aluminum-based injection mold block.
5. The method of claim 1 , wherein the computer menu of customer-selectable values for a cost-affecting parameter of mold manufacture and/or part manufacture unassociated with part surface profile comprises a menu of available injection moldable plastics, such that the computer generated quotation varies based upon which plastic the customer selects for the part.
6. The method of claim 1 , wherein the computer menu of customer-selectable values for a cost-affecting parameter of mold manufacture and/or part manufacture unassociated with part surface profile comprises a menu of possible surface finishes, such that the computer generated quotation varies based upon which surface finish the customer selects for the part.
7. The method of claim 1 , wherein the computer menu of customer-selectable values for a cost-affecting parameter of mold manufacture and/or part manufacture unassociated with part surface profile comprises a menu of number of parts in a production run, such that the computer generated quotation comprises a piece price which varies based upon how many parts the customer selects to be run.
8. The method of claim 1 , wherein the computer calculated quotation comprises a series of piece price quotations covering different lot sizes, the series of piece price quotations varying non-linearly based upon how many parts the customer selects to be run.
9. The method of claim 1 , wherein the computer menu of customer-selectable values for a cost-affecting parameter of mold manufacture and/or part manufacture unassociated with part surface profile comprises a menu of potential delivery times, such that the computer generated quotation non-linearly varies based upon lead time required by the customer.
10. A method of quotation and manufacture of a mold and/or molded part, the method comprising:
assessing a customer's CAD file via computer to determine at least one cost-affecting parameter of mold manufacture and/or part manufacture, the CAD file defining a shape of a part to be molded;
computer calculating a quotation for mold manufacture and/or part manufacture based at least in part upon the cost-affecting parameter determined by computer assessment of the customer's CAD file, the quotation including costs of machining of a cavity into a mold block corresponding in shape to the part to be molded as defined by the customer's CAD file;
communicating the computer calculated quotation to the customer; and
upon acceptance of the computer calculated quotation by the customer, machining the cavity into the mold block corresponding in shape to the part to be molded as defined by the customer's CAD file.
11. The method of claim 10 , wherein the mold block is an aluminum-based injection mold block.
12. A computer program for custom quotation for manufacture of an injection mold and/or manufacture of an injection molded part, the computer program comprising:
an input dedicated for receiving a customer's CAD file, the CAD file defining a shape of a part to be molded;
computer code embodied on a readable medium for analyzing the customer's CAD file to determine at least one cost-affecting parameter of injection mold manufacture; and
an output providing a dollar value quotation for injection mold manufacture and/or part manufacture which includes costs associated with machining a cavity into the injection mold, the cavity corresponding in shape to the part to be injection molded, the output based at least in part on the cost-affecting parameter of injection mold manufacture as determined by the computer code analysis of the customer's CAD file.
13. The computer program of claim 12 , further comprising:
an input dedicated for receiving information of a cost-affecting parameter of mold manufacture and/or part manufacture unassociated with part surface profile, and wherein the output is based in part on the cost-affecting parameter of mold manufacture and/or part manufacture unassociated with part surface profile.
14. The computer program of claim 12 , wherein the input comprises an internet address configured to receive the customer's CAD file.
15. A computer program for automated analysis of a part for conformance with acceptability criterion on injection molding of the part, the computer program comprising:
an input dedicated for receiving a customer's CAD file, the CAD file defining a shape of a part to be molded;
computer code embodied on a computer readable medium for analyzing the customer's CAD file to determine features of the part which fall within and outside of at least one injection molding acceptability criterion; and
an output providing a rendering which highlights physical geometry modification locations relative to remaining unaltered portions of the part surface profile which fall within the at least one injection molding acceptability criterion.
16. The computer program of claim 15 , wherein the injection molding acceptability criterion comprises a determination of whether the part can be manufactured in a straight pull mold.
17. The computer program of claim 15 , wherein the injection molding acceptability criterion comprises a determination of whether the part contains acceptable draft angle.
18. The computer program of claim 15 , wherein the injection molding acceptability criterion comprises a determination of whether mold geometry for the part can be formed through machining with a standard set of CNC machining tools.
19. The computer program of claim 15 , wherein the injection molding acceptability criterion comprises a determination of whether mold geometry can be formed in aluminum or in an aluminum-based alloy.
20. The computer program of claim 15 , wherein the injection molding acceptability criterion comprises a determination of whether the part is acceptably sized for injection mold manufacture.
