Problem 3 (15 points): A local company is producing preforms (tube-like parts) for beverage bottles using an injection molding machine. The molding machine was purchased for 2,500,000 SR The machine is automated and is used for 16 hours/day just for the production of the preforms. Its anticipated life is TO years and expected to operate 250 days per year? The mold (tool), which costs 550,000 SR. produces (225 parts/cycle and expected to operate 200,000 cycles. The total molding cycle time is 75 sec. The plastic molding material costs 8.50 SR/kg, Each molded part weight 25 g The only labor required is for a worker to periodically monitor the machine. Labor rate of the worker is 108.00 SR/hr including overhead. However, the worker also supervises other machines and only spends 20% of his time on this machine. Setup can be ignored because of the long production run. Equipment overhead rate is 30%) The machine availability - 96% and the scrap percentage - 2%, Determine: ROH (a) equipment cost rate (SR/hr) including the overhead. (4 points) (b) tool cost per good piece (SR/pc); (4 points) (c) production rate of good pieces (pc/hr); (3 points) (d) cost per good piece (SR/pc). (4 points)
