Metal powders are blended and mixed in step 1 of a conventional press-and-sinter process in which the total quantity of PM parts to be produced is 20,000, and the total cost of the metal powders is $30,000. The amount of powders per batch in step 1 is sufficient for 350 PM parts. The cost rate of the blending and mixing equipment is $60/hr and the time to setup and run the batch in step 1 is 30.0 min. In step 2, pressing, the cycle time to powder feed, press, eject, and collect the green parts is 12.0 s/pc. Time to set up the press before production is 1.2 hr. With a production run of 20,000 pc, no refurbishing of the punch and die will be required. The cost rate of the press is $60/hr. In step 3, sintering, the flow-through furnace has a sinter processing rate of 3 pc/min, and the furnace cost rate is $66/hr. Determine the total cost per completed PM part.
