Basic Concepts of Metal StampingTypes of Stamping OperationsTypes of Stamping PressesTypes of Stamping DiesMaterial ConsiderationsStamping Advantages and DisadvantagesApplicationsSummaryOther Metal Fabrication ArticlesMetal stamping also referred to as pressing is a lowcost highspeed manufacturing process that can produce a high volumeof identical metal components Stamping operations are suitable for both short or long production runs and be conducted with other metal forming operations and may consist of one or more of a series of more specific processes or techniques such as 1 Punching 2 Blanking 3 Embossing 4 Coining 5 Bending 6 Flanging Punching and blanking refer to the use of a die to cut the material into specific forms In punching operations a scrap piece of material is removed as the punch enters the die effectively leaving a hole in the workpiece Blanking on the other hand removes a workpiece from the primary material making that removed component the desired workpiece or blank Embossing is a process for creating either a raised or recessed design in sheet metal by pressing the raw blank against a die that contains the desired shape or by passing the material bl Progressive die stamping Progressive die stamping uses a sequence of stamping stations A metal coil is fed into a reciprocating stamping press with progressive stamping dies The die moves with the press and when the press moves down the die closes to stamp the metal and form the part When the press moves up the metal moves horizontally along to the next station These movements must be precisely aligned as the part is still connected to the metal strip The final station separates the newlyfabricated part from Transfer Die Stamping Transfer die stampingis similar to progressive die stamping but the part is separated from the metal trip early on in the process and is transferred from one stamping station to the next by another mechanical transport system such as a conveyor belt This process is usually used on larger parts that may need to be transferred to different presses FourSlide Stamping Fourslide stamping is also called multislideor fourway stamping This technique is bestsuited for crafting complex components that have numerous bends or twists It uses four sliding tools instead of one vertical slide to shape the workpiece through multiple deformations Two slides or rams strike the workpiece horizontally to shape it and no dies are used Multislide stamping can also have more than four moving slides Fourslide stamping is a very versatile type of stamping as di The three common types of stamping pressesinclude mechanical hydraulic and mechanical servo technologies Usually presses are linked to an automatic feeder that sends sheet metal through the press either in coil or blank form Image credit DRN Studio/Shutterstockcom Dies that are used in metal stampingoperations can be characterized as either singlestation or multiplestation dies Singlestation dies include both compound dies and combination dies Compound dies perform more than one cutting operation in a single press such as the case of the multiple cuts needed to create a simple washer from steel Combination dies are ones which incorporate both cutting and noncutting operations into a single press stroke An example might be a die that produces a cut as well as a flange for a given metal blank Multistation dies include both progressive dies and transfer dies where notching punching and cutting operations occur in sequence from the same dieset Steel rule dies also referred to as knife dies are were initially used with softer materials such leather paper or cardboard but have also found application in cutting and shaping of metals including aluminum copper and brass The steel strip Image credit Wisconsin Stamping The choice of metal stamping materialsused depends on the desired attributes of the finished piece Stamping is not limited as a fabrication process to just metals there are numerous metal stamping materials that can be processed through stamping techniques such as paper leather or rubber but metals are by far the most commonly used In general metals tend to maintain their malleability and ductility after stamping Those used in precision stamping usually range from soft to medium hardness and carry a low coefficient of flow Some of the customary metals and metal types fabricated through stamping include 1 Precious metals such as silver gold and platinum 2 Ferrous metals especially ironbased alloys like stainless steel 3 Nonferrous metals such as bronze brass and zinc 4 Nonstandard alloys such as beryllium nickel and beryllium copper Ferrous metals are commonly used in stamping operations as their low carbon content means th Some of the benefits of stamping include lower die costs lower secondary costs and a high level of automation compared to other processes Metal stamping dies tend to be relatively less expensive to produce and maintain than those used in other common processes The secondary costs such as cleaning and plating are also cheaper than similar treatments for other metal fabrication processes Stamping machines are relatively easy to automate and can employ highend computercontrol programs that provide greater precision faster production and quicker turnaround times The high level of automation also lowers the cost of labor One of the disadvantages of stamping is the higher cost of presses The dies must also be acquired or created and producing custom metal stamping diesis a longer preproduction process Dies can also be difficult to change if the design must be altered during production Stamping is used in a variety of applications especially those involving threedimensional designs lettering or other surface engraving features Such stamping products are commonly produced for home appliance manufacturers automotive companies thelighting industry telecommunications services military and defense aerospace industries medical equipment manufacturers and electronics companies Odds are you have a product in your home that has parts created through metal stamping because it is a process used in everything from your household appliances to your cars The specific products and components can range from simple stamping items such as metal clips springs weights washers and brackets to more complex designs such as those found in engine bases or friction plates This process is used for producing both parts for large machinery and also incredibly detailed small parts Microprecision stampingcan create parts with diameters of up to 0002 inches Electronic s This article presented an understanding of metal stamping operations and machine presses For more information on related services consult our

INTRODUCTION TO SHEET METAL FORMING PROCESSES

The definition of stamping at normal temperature a metal (or nonmetal) sheet is pressed on a stamping press machine by a stamping die to cause separation or plastic deformation thereby obtaining parts having a certain shape size and performance.
