Die Basics 101 Begins With Eight Basic Components
A stamping tool is an exclusive precise tool that shapes and cut sheet metal in the desired shape or profile. Special types of hardenable steel are used to create the die’s cutting and section for forming. Dieses also have cutting and forming sections that are made from carbide or various other tough, wear-resistant materials.
Most stamping dies are constructed of several progressive mold components, including die plates, shoes, die sets, guide pins, bushings, heel blocks, heel plates, screws, dowels, and keys. Die sets also require stripper, drawing pads, pressure and the equipment used to fix them such as shoulder bolts, spools keepers, retainers, and spools along with gas, coil, or urethane springs.

Die Plates, Shoes, and Die Sets
Die plates, shoes, and sets of dies are steel or aluminum plates which correspond to the dimensions of the die. These plates serve as the basis for mounting the work press die components. These parts must be machined milled or ground to ensure they are parallel and flat within a specified tolerance. Although grinding is the most popular however, a surface milled could be just as exact as a ground surface.
Most die shoes are made from steel. Aluminum is also a well-known die shoe material. Aluminum weighs about one-third that of steel. It is able to be easily manufactured and special alloys may be added to to give it greater compression strength than low carbon steel. Aluminum is also an excellent choice for blanking dies since it can absorb shocks.
The die set is composed of the lower and upper shoes, that are joined together through guide pins. The lower shoe of the die set usually has machined or holes cut with a flame. This allows scraps and slugs of the die to flow freely into the press bed. These holes can also serve as clearances to gas springs as well as other die components.
The force that can be expected when cutting or creating the die shoe determines its size. The coining die is used to compress metal through pressing it against two sections of the die. Thus, a more robust die shoe is needed as opposed to a bend die.
Guide Pins and Bushings
Guide pins, also called guide posts or pillars, function together with guide bushings to match the lower and upper stamping die shoes in a precise manner. These components that are precision-ground are typically produced in less than 0.0001 inches. They can be mounted using many different mounting methods press die components however there are only two types of basic guide pins, friction pins for bushings and ball bearing-style Pins.
Friction pins are precision-ground pins that are slightly smaller than the guide bushing’s inner diameter. Pins are manufactured from hardened tool steel while bushings are usually made from or covered with a special wear-resistant substance called aluminum-bronze. The aluminum-bronze may contain graphite-filled plugs that aid to reduce friction and wear that occur to the bushings and pins.
Heel Blocks and Heel Plates
Heel blocks are steel blocks that are precision-machined, screwed, doweled, and are often welded to the upper and lower die shoes. They contain components called wear plates and function to adsorb any side thrusts that could be generated during the cutting and the forming process. They are especially important in situations where the force produced is only one-directional. Too much force generated from one direction alone can result in the guide pins to shift that causes an unbalanced cutting and forming parts.
