Thermoforming & Vacuum Formed Products worked example
Nesting Yield at 99% target nesting yield: a worked example in thermoforming & vacuum formed products
Push target nesting yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when nesting yield in thermoforming and vacuum formed products needs a clean rate and gap-to-target you can put on a tier board.
The inputs for this scenario
- Parts scrapped from the nested layout: 8 units (unchanged)
- Total part cavities in the sheet layout: 250 units (unchanged)
- Target nesting yield: 99 % (raised for this scenario; the documented default is 95)
Working through the calculation
- Applying the documented formula (Nesting Yield rate = affected amount รท total amount) to the inputs above produces each figure below.
- At this operating point the engine returns 3.2 % for rate, the number this scenario is built around.
- At this operating point the engine returns 95.8 points for gap to target.
- At this operating point the engine returns 8 count for affected count.
- At this operating point the engine returns 250 count for total count.
How this compares with the baseline
- Against the tool's baseline example, where target nesting yield sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
- It computes the scrap rate as affected parts divided by total nested cavities, and reports the gap in points between that rate and your target yield. 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.
Results at a glance
- Rate: 3.2 % (headline result)
- Gap to target: 95.8 points
- Affected count: 8 count
- Total count: 250 count
