Die-cut Part Inspection
Die-cut part inspection: for short shot, burrs, contour anomalies, out-of-tolerance dimensions and missing or extra parts on die-cut parts such as tape/film/foam/conductive fabric, template comparison plus telecentric measurement and AI judgement output OK/NG.
Application Overview
Short shot and burr inspection of die-cut adhesive / film / foam parts
Inspects short shot, dimensions, burrs, irregular contours and bonding position on die-cut parts (adhesive / film / foam); template comparison against the die-cut pattern and dimensional measurement are performed, outputting OK/NG.
Die-cut parts are stamped functional pieces (adhesive, film, foam, conductive fabric and so on); short shot, burr and contour offset directly affect assembly and lamination, making them parts with high batch consistency requirements.
This station covers the appearance and dimensions of die-cut parts, focusing on short shot, burr / flash, contour anomalies, out-of-tolerance dimensions and extra / missing parts; comparison is made against the die-cut pattern template.
Inspection is at the post-die-cutting process step, imaging single sheets or a continuous strip; irregular parts are positioned by template matching and dimensions are measured with telecentric optics, adjusted to the specific material.

What This Station Actually Has to Judge
| inspection item | Description |
|---|---|
| short shot | Local short shot, incomplete cutouts |
| Burr / Flash | Cutting Burr |
| Contour Anomaly | Outline offset, bulging edge |
| out-of-tolerance dimension | Side length and hole diameter out of tolerance |
| Extra Part / Missing Part | Missing Parts in a Continuous Strip |
| foreign matter | Adhered Particles |
| stain | Oil Stains, Discoloration |
Why Inspect
Problems with manual visual inspection at this step
Die-cut parts are produced in large batches with high consistency requirements; short shot and burrs directly cause assembly or bonding failures, and manual sampling has low coverage and easily misses defects.
Irregular die-cut parts are hard to locate with fixed thresholds; template comparison is needed to establish the coordinate system before judging short shots and contour.
- Short shots and burrs affect assembly fit
- High consistency requirements for mass production
- Irregular parts: fixed thresholds make positioning difficult
- Manual sampling gives low coverage
How Inspect
Stations and Inspection Chain
- 01 Load and position the die-cut part
- 02 Template matching locates the pattern
- 03 Region Segmentation
- 04 Short shot judgement
- 05 Contour Comparison
- 06 Telecentric dimension measurement
- 07 Counting Multiple Missing Parts
- 08 OK/NG output
- 09 Image and data archiving
How to Inspect
For die-cut parts, template matching uses the die-cut shape as a reference for positioning, then short shot and contour judgement are performed in fixed regions and dimensions are measured with a telecentric lens; this is template comparison + dimensional measurement imaging.

Common Question
What Does Die-Cut Part Inspection Check?
Can it replace manual labor?
What Inspection Accuracy Can Be Achieved?
How Are Odd-Form Parts Positioned?
Can Missing Parts in a Continuous Strip Be Counted?

Do I Need to Re-Tune When the Die-Cut Pattern Changes?
Submit sample testing
Typical OK/NG die-cut part samples can be sent for a measured trial: a template is built from the die-cut shape and a telecentric measurement solution is defined.

Can This Application Be Done? Sending a Sample for Testing Is the Most Direct Answer
Incoming material, part orientation and cycle time vary widely from factory to factory. Send us real samples and we will run imaging and judgement validation against your production line conditions, then give you a configuration proposal you can actually implement.
