When producing rotary dies, the quality of the rotary wooden shell directly affects cutting precision, machine stability, and tool life.
Here’s a simple 5-step guide to help you identify high-quality rotary die boards from inferior ones — fast and accurately.
Check the outer appearance for wormholes, scars, or cracks.
✅ Smooth surface, no wormholes or scars → High-quality board
❌ Rough surface, visible holes or cracks → Reject immediately
Use a caliper to measure multiple points.
The standard tolerance should remain within ± 0.2 mm.
Uniform thickness means better balance and laser-cutting precision.
Measure both ends of the cylinder:
Acceptable deviation range = −3 mm to +2 mm
This ensures the rotary board fits perfectly on your die-cutting drum.
Place the shell on a standard jig to test curvature alignment.
There should be no visible gaps, and the length must be accurate.
A perfectly curved board ensures smooth rotation during production.
Perform a rotary laser-cut test to evaluate edge quality.
Smooth, clean edges after laser cutting = high-density, stable shell suitable for long-term die-making use.
At YITAI, every Rotary Die Board undergoes strict quality inspection and laser test verification to ensure high precision, strength, and stability.
Our shells are designed to support rotary die-cutting applications across packaging, printing, and corrugated box industries — helping die makers achieve consistent accuracy and longer service life.
