Why Edge Trimming Matters in Smart Card Production

After chip placement and wire embedding, inlay sheets require precise edge trimming to achieve final card dimensions (CR80 standard: 85.60 x 53.98mm). The quality of this process directly impacts:

  • Card Dimension Accuracy: ISO 7810 ID-1 compliance requires +/-0.3mm tolerance on final card size
  • Lamination Quality: Clean edges prevent delamination and air bubbles during overlay lamination
  • Aesthetic Finish: Smooth, burr-free edges enhance premium card appearance
  • Dies & Tooling Compatibility: Precisely trimmed sheets fit die-cutting tools with minimal waste

Frequently Asked Questions

What is the trimming tolerance?

Achieves +/-0.05mm dimensional accuracy, well within ISO 7810 requirements. The CNC servo system ensures consistent results across all four edges.

Can it handle different sheet sizes?

Yes. Supports A4 maximum with programmable trim dimensions for any multi-up layout pattern. Changeover between patterns takes under 2 minutes.

How does vision alignment work?

CCD camera detects registration marks or sheet edges, calculating offset and rotation. The CNC controller applies corrections before each cut for perfect alignment.
