## Inspection equipment: Nikon VMR-6555 CNC video measuring system

Dimensional measurement, nesting checks and drop simulation address different parts of the tray inspection plan.

| Equipment | Model | What it checks |
| --- | --- | --- |
| Nikon CNC video measuring system | VMR-6555 | Thermoformed part dimensions |
| 2.5D optical measuring system | VMS-5040 | Thermoformed part dimensions |
| Anti-stack tester | — | Jamming when trays are nested |
| Drop tester | — | Handling drops, to refine tray design |

## Tray tolerance: outline tolerance from 1.2 mm to 0.3 mm

These figures apply to thin-gauge thermoformed trays. Trays for automated production lines are controlled to +0.3 / −0.2 mm.

| Thin-gauge thermoformed tray engineering capability (mm) | 2018–2019 | 2020 | 2021 | 2022 | 2023–2024 | 2025–2026 |
| --- | --- | --- | --- | --- | --- | --- |
| Maximum depth | 50 | 60 | 70 | 80 | 100 | 120 |
| Outline tolerance | 1.2 | 1 | 0.8 | 0.6 | 0.5 | 0.3 |
| Groove tolerance | 0.5 | 0.5 | 0.3 | 0.3 | 0.2 | 0.1 |
| Male-mold tolerance | 0.3 | 0.3 | 0.2 | 0.2 | 0.15 | 0.1 |
| Female-mold tolerance | 0.2 | 0.2 | 0.1 | 0.1 | 0.08 | 0.05 |
| Minimum width between grooves | 5 | 4 | 3 | 2 | 1.5 | 1 |

Calculated from the first and last table periods: outline tolerance value decreased 75%; groove tolerance value decreased 80%.
