| Product > Rotary Diemaking Rules > Rotary Special Rules |
The broad range of National special rotary rules has been specifically engineered to provide optimum performance.
Each has been subjected to rigorous evaluation to determine the pressure required for a given substrate, blanket penetration, edge appearance after use, longevity of the rule and bendability.
