An Aluminum alloy die casting weighs 0.63 kg and the weight of the connected gating system = 0.25 kg. Hourly production rate of the die casting operation = 80 pcs/hr. The unit heating and pouring energy for this alloy = 1080 J/g. Newly installed automated die casting equipment cost $250,000 and will not require major overhaul for the next 1,200,000 cycles. Aluminum is purchased at $1.95/kg. Cost of energy used is $0.15/kWh. A die with a single cavity is used, costing $7500 and is good for 150,000 castings. Scrap rate is 2%. The trimming process is contracted out. The gating material is recycled. Manual labor is used only to load/unload the automated equipment at $25/hr. (1kW = 1000J/s) a) What is the cost per hour for this casting operation? b) What is the cost per good part produced for a production order of 10,000 (salable) pieces?
