What Is Steel Rule Die Cutting?
Steel rule die cutting is a type of die cutting used to fabricate raw materials into a certain shape. It involves punch cutting a selected stock material into a particular form or pattern with a sharp steel rule against a flat surface. This technology is a material displacement method, meaning it doesn’t change the composition of the material itself. It only manipulates and separates the desired part from the waste.
How It Works
Steel rule die cutting uses a custom steel tool to punch material into a certain shape. Three components are involved: a cutting edge, a die board and a rubber ejector. The die board is a flat surface made from hard materials like wood, steel or composite, which has a thin groove the shape of the desired part cut into it, usually by a laser.
The cutting edge — a thin metal blade — is bent into shape either by hand or machine and placed onto the die board, where it is overlaid with a rubber ejector material.
Operating the die involves feeding a material in and stamping the tool into it. This causes the material to break along the cutting edge. Then, the rubber ejector pushes the cut part out of the steel die. An ejector can cover the entirety of the die or only a part of it. Steel rule dies can also be equipped with a creasing tool, which, rather than completely severing the material, cuts partway through it, creating a
