Metal stamping is the process of cutting and shaping metal alloys
into specific forms, especially to be used as components for large
machinery or structures. Metal sheets can be molded into different
pre-determined shapes for use as regular products like pans and cans.
The most common alloys that are used in metal stamping are steel, zinc,
nickel, aluminum and titanium. Metal stamping is a very cost-effective
and productive way of producing many kinds of metal products on a large
scale.
In metal stamping, the metal sheets are placed in a die or a press
tool that has a specially designed cavity that gives the preferred shape
to the metal sheet. The upper part of the die connects to the press
slide while the lower component connects to the press bed. A specific
component known as the punch pushes the metal sheet through the die,
thus performing the actual shaping operation. After pressing, the metal
is plated with gold, palladium, nickel or tin to prevent corrosion.
Plating also increases the wearability and solderable nature of the
product. Sometimes, the sheet is also pre-plated before the stamping
process, and then the product is cleaned to remove excess
metal stamping
oils and films. The product is then heat treated to make it stronger
since it is still in the soft state after stamping. The product is then
subjected to the deburring process for removing the sharp corners. This
is done by using chemicals or abrasives. Metal stamping also involves
other metalworking processes like piercing, blanking, forming and
drawing on the same machines.
Stamping presses have specific force, speed and precision for giving a specific shape to the metal. There are two types of
metal stamping
presses: Mechanical and hydraulic. These are available in an extensive
range of capacities, sizes, stroke lengths and operating speeds.
Metal stamping is slowly replacing other metal forming processes like
die casting,
forging, fabricating and machining. One reason for this is the very low
costs involved in metal stamping. The dies used for metal stamping cost
less than those used in forging and casting. Also, the metals used in
metal stamping can be harder than those used in other processes, thus
making the end product stronger. The cost of the secondary processes,
like cleaning and plating are also considerably reduced.
Moreover, there are certain products that have to be produced only
through metal stamping: Base weights, brackets, balance clamps, brake
flanges, conveyor flights, bushing seats, engine bases, flywheel shrouds
and friction plates. There are also different kinds of metal stamping
including: Deep drawn stamping, electronic stamping, Fourslide stamping,
medical stamping, progressive die stamping and short run stamping. The
most commonly used type is the progressive die drawing wherein a metal
sheet is drawn through a series of dies and stamping is done by all the
dies simultaneously, thus considerably reducing the time it takes.
