Answer:
Sand-Casting Production Line:
The total hourly cost to operate the line is:
= $2,339.
Explanation:
a) Data and Calculations:
Costs of automated mold-making machine per hour = $120
Cost of personnel tending the mold-making machine = 45
Cost of mold-making machine = 600
Average cost of mold sand per mold = $0.12 * 2,500 = 300
Cost of energy to heat the molten metal for pouring = $0.06 * 164 10
Cost rate of the pouring line, including heating crucibles = 33
Cost of three workers who operate the pouring line = 60
Cost of buffer storage system used for cooling the castings = 40
Cost of break-away area workers = 38
Cost of casting metal = $1.55/kg * 4.3 * 164 = 1,093
Total hourly cost to operate the line = $2,339
