DIE CUTTING, by simple definition, is the process of using a die to shear webs of low-strength thin materials, such as rubber, foil, cloth, paper, films, pressure sensitive adhesive tapes and foam. Commonly produced items include gaskets and labels.
World-wide, Marian has one of the largest "fleets" of die cutting machines. Our highly trained design, electrical and mechanical engineers manufacture our die cutting equipment in-house in two well equipped machine shops. We have been die cutting for over 50 years. We are very proud to be industry experts and offer our "die cutting 101" below.
Different Types of Die Cutting
Rotary Die Cutting -
Rotary die cutting uses a cylindrical die on a rotary press. A long sheet or a web of material is fed through the rotary press into an area which holds a rotary tool that will cut out shapes, make perforations or creases, or even cut the sheet or web into smaller parts. Rotary die cutting creates the same part repeatedly at very tight tolerances.
Flat Bed Die Cutting -
With flat bed die cutting shapes are stamped out of material utilizing steel rule dies that are adjusted accordingly to varying degrees of a hydraulic or mechanical presses. (Sometimes referred to as “clicking”) Advantages of flat bed die cutting are seen with lower quantities, larger die cuts, and thicker materials.
Match-Metal Die Cutting -
In match metal die cutting, materials pass through a cutting die constructed of a top and bottom die which are matched (male/female) to provide an extremely precise cut. Match Metal die cutting is typically used for higher volume applications which require extreme precision.
Compound Die Cutting -
Compound die cutting performs multiple steps in one pass. The compound die cut implements more than one operation during the cutting cycle.
Punch Press -
In a punch press, material runs through the press while a hydraulic ram at the top powers the die to cut the material. This type of die cutting is advantageous for speed and productivity.
Additional Capabilities of the Die Cutting Process
Multilayer Laminations with PSA -
Multiple webs come together in a single pass to create a complex multilayer part.
Zoned Adhesive -
Custom patterns of adhesive are laminated to material during the die cutting process, leaving adhesive only in the specified area(s).
Kiss Cutting -
Kiss cutting is a process where a laminated material is die cut to the liner without cutting through the liner, leaving the die cut part affixed to the liner. Parts can be rolled around a core on the liner making them easier to handle.
Pull-Tabs and Extended Liners -
Materials with top and bottom liners are cut so that a portion of the liner is cut to extend the material to leave a pull-tab. This pull-tab contributes to ease of handling and placement.
Perforation Die Cutting -
This process does not fully trim the materials away from the original shape, but instead creates a perforated area that remains in place until it is ready to be detached.
