Powder Metallurgy & Sintered Parts worked example
Tooling Amortization at 99% press efficiency: a worked example in powder metallurgy & sintered parts
Push press efficiency up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when tooling amortization in powder metallurgy and sintered parts is being committed and you need a throughput number you can defend.
The inputs for this scenario
- Parts pressed on this tool set: 1,200 units (unchanged)
- Press running time: 8 hr (unchanged)
- Press efficiency (good-part rate): 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Raw tooling amortization = completed output รท runtime) to the inputs above produces each figure below.
- At this operating point the engine returns 149 units for effective throughput, the number this scenario is built around.
- At this operating point the engine returns 150 units for raw throughput.
- At this operating point the engine returns 99 % for efficiency.
- At this operating point the engine returns 8 hr for runtime.
How this compares with the baseline
- Against the tool's baseline example, where press efficiency sits at 90% and the headline result is 135 units, this scenario comes in 10% above the baseline at 149 units.
- It computes raw press throughput as parts pressed per running hour, then derates by efficiency to give the effective good-parts-per-hour rate used to amortize tooling. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
