Custom Sheet Metal Stamping Components

Die components are the parts that make up a complete die set. They consist of items such as pins, bushings, top shoes and bottom shoes. The following terms describe various die components and forces that affect them.

DIE BUTTONS hardened tool steel component that establishes a sheer clearance in piercing

DIE LIFE The vertical section of the lower die cutting edge before the relief starts

DIE RING Type of die block construction that dowel pins are used to locate and position the die ring on the die pad or on the die shoe

ACUTE-ANGLE DIES used for 90 degree bends

BEADING DIES used to stiffen flat sheets and sometimes allow thinner materials to be used

BLANKING DIES These dies sheer a flat part from a strip of sheet metal

BOX FORMING DIES Require a high punch and low die to form the box

BREHM TRIMMING DIES Used to trim boxes, cups and shells that include tabs, notches and angles

BULGING DIES Used to expand or bulge drawn shells; used to produce artificial limbs, doorknobs, and teapots

CHANNEL FORMING DIES used to make channels in gooseneck or single stroke channel dies; include a spring pressure release mechanism to eject the formed part

COINING DIES Change the metal thickness through squeezing to leave an impression on the surface of the punch or die

COMPOUND DIES combine two or more cutting operations in every press stroke

COMPRESSION DIES use compression to form a slug or blank, plastically deforms the metal

CORRUGATING DIES Use corrugation to strengthen the sheet or provide design

CURLING DIES Form a curled up portion on the sheet or pan

DRAW DIES Reduce flat, round or rectangular blanks into three dimensions forms

FORMING DIES Used in conventional presses to form exact shapes

GOOSENECK DIES V-shaped dies with clearance for return flanges

HEMMING DIES Used to turn over the edges of a sheet to form a rigid, smooth edge

INVERTED DIES Die components are mounted opposite of conventional dies to produce parts that are too large to pass through the press bed or bolster plate

IRONING DIES Used to reduce the wall thickness and produce a smooth, uniform finish on shell walls by having the clearance space between the punch and the die wall smaller than the thickness

LAMINATION DIES Progressive dies used specifically for high volume parts for the stamping industry

MULTIBED DIES Used in large production runs that usually would require two or more dies

OFFSET DIES Uses two 90 degree bends to form an offset

PIERCING DIES Used to produce holes in flat stock

PINCH RIMMING DIES combine drawing, forming and sizing to produce uniform trimmed edges

PROGRESSIVE DIES Consist of two or more stages where different operations are performed n a metal strip

RADIUS DIE Used when the radius is four times larger than the material thickness

SEAMING DIES Used to make seams in tubes or sheets

These types of dies are common components used in precision metal stamping. Each component performs a unique function in the sheet metal stamping process.
