When adhesive penetrates through the face material of a pressure-sensitive lamination.
Some cutting dies are equipped with air ejection jets to eject die cut parts or scrap parts out of a die.
Air escape holes are often required in a die blade or at the back of the die to allow the built up air in a die cavity to escape during the die cutting process. If air holes are not provided the captured air in a die cavity can impede the die cutting action and hinder the ejection of the die cut piece from the die after the die cutting cycle. In clicker and high dies, the die maker will often grind several grooves in the back of the die to allow air to escape from the die. Also used on auto platen stripping & blanking dies.
Made totally from steel. This usually refers to all-steel clicker dies or solid milled clicker dies vs. steel rule dies. Learn more from our blog

BACK UP PLATE
A plate normally placed on the back of a die.
Also called leveling knives as used in steel rule dies to balance the load on a platen press.
In reference to cutting die blades, the bevel or bevels of the cutting edge determine how a blade penetrates the material being die cut. The bevel on a die blade is identified by the number of degrees on the bevel or as an inside bevel or outside bevel. Some steel rule blades have a double bevel for certain cutting applications.
This die type is covered here because it employs a form of steel rule, although it is used to convert metal. Normally, the die is made of two parts; the top (female) section, of steel rule set into dense material, sometimes maple plywood; the bottom section (male), a hardened plate which mates with the inside line of the top section to form a shearing effect on the materials being cut. This die is also known as a shearing die, stamping die, or metal blanking die. Also used on auto platen presses with a blanking section to separate the finished carton from the die cut scarp sheet.
BONDED STEEL RULE DIE
A steel rule die which has a top and bottom metal plate which are identical. The die design is laser cut or milled into the plates and the plates are separated by spacers. After the die is knifed, the center core is filled with a bonding material.

(3) Usually refers to the engraving on a rotary die cutter that die cuts a single shape.
CENTER BEVEL RULE
A steel rule blade where the cutting edge is centered in the middle of the thickness of the die blade.
A die blade that creates a slice or tear cut in a die cut piece. It can be anywhere in a die configuration where a separation is needed or could be outside the die to help break away the web of material to relieve cutting pressure to aid in improved die cutting techniques.

COMPRESSION SET RESISTANCE
The compression set of a material is the permanent deformation remaining when a force that was applied to it, is removed. The term is normally applied to soft materials such as elastomers. Materials such as Poron Foam have excellent compression set resistance, meaning that these open-cell materials typically resist compression set and force relaxation better.

CUTTING and/or CREASING PLATE
In “onto” cutting where die blades strike against a cutting base the base plate is called a cutting plate, normally made out of flat ground stainless steel.
In die cutting, the cutting head normally refers to the head of the cutting press into which a cutting die is mounted.
This refers to the amount of pressure that a cutting press exerts in the downward stroke of the cutting press. The pressure is normally identified in tons of cutting pressure. Generally a common rule of thumb states that it takes about 500 pounds per lineal inch of blade to accomplish a clean die cut, but that figure varies according to the material being cut and other conditions.
The surface against which the cutting die strikes after the die has penetrated the material being die cut. The cutting surface in the case of “into” cutting allows the die to slightly penetrate the cutting surface to create a clean cut and in the case of “onto” cutting the die strikes against or onto a hardened surface.

The method of using sharp edged cutting dies to cut out shapes from a wide array of soft to semi-rigid materials. The action of making piece parts from bulk materials using cutting dies and presses.
DIE EDGE BEVELS
The bevel on a die blade depends on the intended use of the die blade. The bevel is generally pre-shaped in the blade. A blade can have a short or long bevel, a center bevel, or multiple bevels depending on what the blade is to be used for. Most steel rule die blades have a counter bevel on the cutting edge required in manufacturing the blade, but clicker and high die blades generally do not have a counter bevel. The reason probably is that a clicker and high die blade is heat treated harder and lasts longer in cutting when used in “into” cutting.
The view looking down on the sharp edges of the knife, also called the “inside view” in paperboard cartons.
A die stop is a block of steel that is placed close to the mechanical or hydraulic posts of a cutting press. The die stop limits the downward stroke of a press so that the die attached to the head of the press is limited to not travel below the die stops.
