Use this problem description to answer the following three questions.  A plastic molding machine produces a product whose annual demand is in the millions. The machine is automated and used full time just for the production of this product. The molding cycle time = 45 sec. No tooling is required other than the mold, which cost $100,000 and is expected to produce 1,000,000 moldings (products). The plastic molding compound costs $1.20/lb. Each molding weighs 0.88 lb. The only labor required is for a worker to periodically retrieve the moldings. Labor rate of the worker = $18.00/hr including overhead. However, the worker also tends other machines and only spends 20% of his time on this machine. Setup can be ignored because of the long production run. The molding machine was purchased for $500,000 installed, its anticipated life = 10 years, and it operates 6,000 hours per year. Equipment overhead rate = 30%. Availability = 100% and scrap rate = 0.
