1. 1 As Class Convenes u Find your team table u Pick up your folders u Sign attendance sheets

2. 2 Session Agenda  Quiz 5 min Quiz  Costs 20 min u Injection Molding20 min

3. 3 Meeting Minutes u The RFP requests your meeting minutes. These minutes are to be posted in the Team Group folder. u Teams B & H have posted minutes. I could not find anything for the other teams. u Minutes need to be more than a bulleted list of things done; there needs to be detail leading up to the bulleted items.

4. 4 Learning Objectives u Achieve awareness the various costs that make up a product’s ultimate price in the store u Achieve awareness injection molding process and costing

11. 11 Product Cost

12. 12 Final Manufacturing Cost

13. 13 1-3-9 Heuristic for Costing u For large volume products produced mainly in house –the manufacturing cost is about 3 times the materials cost –the selling price is about 9 times the materials cost

14. 14 Cost Models u need to be developed early in development process u are used in Refining Specifications u are refined and improved as design work proceeds

15. 15 Source of Components u Purchase vendor designed and made components u Have vendor made in-house designed components u Design and make components in- house

16. 16 Injection Molding u Very popular u Good for high (>100,000) volume components

17. 17 Injection Molding Machine Insert picture of machine from Kalpakjian, page 630

18. 18 Injection Molding Tool Costs u Depend on the –number of cavities in the tool –size of the part –complexity of the part –needed surface finish u 10K to 300K Dollars/tool

19. 19 Injection Molding Costs u Depend on the –cycle time –amount of plastic (part, sprus, and runners) –setup and takedown time –labor cost

20. 20 Needs Analysis Vs Manufacturing Cost u Little demand for $400 calculator (HP 35) - Stanford Research Institute u Low number of cavities in injection molding tools u Demand so high could afford to re- tool after 2 years (about a 4 year life expected)
