Metal stamping is a common manufacturing process. Also known simply as metal pressing, it involves the use of a stamping press to deform and shape a metal workpiece. Metal workpieces typically consist of sheet metal. To alter the shape of a piece of sheet metal, manufacturing companies can stamp it. How does metal stamping work exactly?

Although it sounds complex, metal stamping is a relatively simple manufacturing process. It requires the use of a stamping press to deform and shape a metal workpiece. Stamping presses are heavy-duty machines that essentially sandwich a metal workpiece between a set of dies. They typically have one die on top and another die on the bottom.
During use, the stamping press will push the top die down onto the bottom die. Since the metal workpiece is placed between these two dies, it will take their respective shape. The bottom of the metal workpiece will take the shape of the bottom die. The top of the metal workpiece, on the other hand, will take the shape of the top die.
Although there are several types of stamping presses, most of them consist of a few basic parts. They have a bolster plate, for instance. Located on the top of the bed, the bolster plate is the component on which the bottom die is placed.
In addition to a bolster plate, most stamping presses have a ram or slide. The ram or slide is the top part that presses down onto the metal workpiece. Some of them use a mechanical ram or slide, whereas others use a hydraulic ram or slide. Regardless, most stamping presses have this part. It’s one of the main components of a stamping press, and it’s needed to deform and shape metal workpieces.
Metal stamping has become a popular manufacturing process because of the benefits it offers. It’s considered a cold-working technique that, like other cold-working techniques, doesn’t heat-related changes to the metal workpieces with which it’s used. Metal stamping won’t expose metal workpieces to heat. Therefore, there’s no risk of heat-related changes. Metal workpieces can be deformed and shaped via metal stamping without being exposed to heat.
Metal stamping is also a cost-efficient manufacturing process. By using metal stamping, manufacturing companies can produce products more quickly and efficiently. The efficient nature of metal stamping makes it a popular choice among large manufacturing companies.

Automotive stamping machine presses are one of the most commonly used pieces of equipment in automotive manufacturing. In an assembly plant, stamping presses transform sheet metals into complicated part geometries such as hoods, fenders, or door panels. Stamping presses are usually characterized by both Hydraulic and Process filter applications, impacting the reliability of the press, and the quality of the stamped part/surface finish, respectively.
From a production perspective, stamping is a critical stage before E-coating and painting. Before stamping, the sheet metal is usually pre-washed with felt cleaning rollers to remove any solid contaminants from its surface (metal, silica, fibers). When particles remaining on the sheet metal are submitted to a multi-tonne load, they create 'marks' on the stamped surface. These marks usually generate quality defects throughout the pre-treatment, e-coat, or painting phases. The stamping press submits filters to harsh working conditions such as cyclic variations in flow and pressure.

Depth filtration for stamping process exhibiting a Beta >5,000 filtration efficiency combined with long service life. This filter ensures that the coolant is clean and prevents the nozzles of the low-pressure washing system from clogging. The pre-wash is essential as it helps avoid 'marks' on the sheet metal – the pressure applied by the press on the metal can be a few thousand tons

Athalon™ Return Line Filter Elements Profile® Coreless Filter Elements Supralon SUPRAdisc Why not view our webinar on parts washing? Athalon on-line and off-line filters ensure that the particulate contamination resulting from wear mechanisms is maintained under control even in the most severe operating conditions. Usually, on such critical equipment, there are many components very sensitive to particles > 15µm like servo-valves or variable displacement pumps. Athalon stress-resistant filters ensure that the fluid cleanliness level is fully under control to maximize the uptime of the equipment while protecting the critical hydraulic components. Removing these elements from the hydraulic fluid, SUPRAdisc™ filter modules, and Purifiers provide the best result. These two items working off-line are incredibly efficient at removing varnish and water. SUPRAdisc lenticular filter modules are made of a cellulose fiber-based medium, combined with resins and additives, while purifiers rely on 'mass transfer under vacuum' technology.
