Thermoforming & Vacuum Formed Products worked example
Line Throughput at 99% line performance efficiency: a worked example in thermoforming & vacuum formed products
What does the result look like when line performance efficiency reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when line throughput in thermoforming and vacuum formed products is being committed and you need a throughput number you can defend.
The inputs for this scenario
- Good parts completed in the run: 1,200 units (unchanged)
- Actual line run time: 8 hr (unchanged)
- Line performance efficiency: 99 % (raised for this scenario; the documented default is 90)
Working through the calculation
- Applying the documented formula (Raw line throughput = completed output รท runtime) to the inputs above produces each figure below.
- At this operating point the engine returns 149 units / hr for effective throughput, the number this scenario is built around.
- At this operating point the engine returns 150 units / hr 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 line performance efficiency sits at 90% and the headline result is 135 units / hr, this scenario comes in 10% above the baseline at 149 units / hr.
- A figure at this level is achievable when line performance efficiency is genuinely sustained, not just peaked for a shift. It assumes a single steady run time and one efficiency factor, so it will not reflect throughput that varies sharply between the start-up ramp and steady state.
Results at a glance
- Effective throughput: 149 units / hr (headline result)
- Raw throughput: 150 units / hr
- Efficiency: 99 %
- Runtime: 8 hr
