Die cutting is the general process of using adie toshearwebs of low-strength materials, such asrubber,fibre,foil,cloth,paper,corrugated fibreboard,chipboard,paperboard,plastics,pressure-sensitive adhesive tapes,foam, andsheet metal. In themetalworking andleather industries, the process is known asclicking and the machine may be referred to as aclicking machine.[1][2] When adinking die ordinking machine is used, the process is known asdinking.[1][3] Commonly produced items using this process includegaskets,[4]labels, tokens, corrugatedboxes, andenvelopes.
Die cutting started as a process of cutting leather for the shoe industry in the mid-19th century.[5] It is now sophisticated enough to cut through just one layer of alaminate, so it is now used on labels,postage stamps, and otherstickers; this type of die cutting is known askiss cutting.[6]
Die cutting can be done on eitherflatbed orrotary presses. Rotary die cutting is often done inline withprinting. The primary difference between rotary die cutting and flatbed die cutting is that the flatbed is not as fast but the tools are cheaper. This process lends itself to smaller production runs where it is not as easy to absorb the added cost of a rotary die.
Rotary die cutting is die cutting using a cylindrical die on a rotary press and may be known as a rotary die cutter or RDC. A long sheet or web of material will be fed through the press into an area known as a "station" which holds a rotary tool that will cut out shapes, make perforations or creases, or even cut the sheet or web into smaller parts. A series ofgears will force the die to rotate at the same speed as the rest of the press, ensuring that any cuts the die makes line up with the printing on the material. The machines used for this process can incorporate multiple "stations" that die cut a particular shape in the material. In each of these stations lie one or more of these geared tools or printing cylinders, and some machines use automatic eye registration to make sure the cuts and/or printing are lined up with one another when lower tolerances are required.
Dies used in rotary die cutting are either solidengraved dies, adjustable dies, or magnetic plate tooling. Engraved dies have a much highertolerance and aremachined out of a solid steel bar normally made out of tool steel. Adjustable dies have removable blades that can be easily replaced with other blades, either due to wear or to cut a different material, while magnetic plate tooling has a cylinder that has magnets placed in it, and an engraved metal plate is attached or wrapped around the base cylinder holding onto it by the force of the magnets.
Dinking is a manufacturing process. Dinking uses special dies called dinking dies, which are hollow cutters. The edges of the dies are usually beveled about 20° and sharpened. The material is punched through into a wood or soft metal block in order to not dull the edges.[7] The die may be pressed into the material with a hammer or a mechanical press.[4][8]
