Leading Sheet Metal Stamping Manufacturers

Sheet metal stamping doesn't involve heat, save during some specialized procedures. Instead, a cold-forming process is used. The part may come out hot even though no heat is applied because of the friction that the press's force causes to form between the metal and the die.

Sheet Metal Stamping Machines

Specialized equipment is needed for sheet metal stamping processes. Stamping presses are the machines that are used the most. A press is a device that can apply pressure to a metal blank to shape it in the desired manner. It can be mechanical, hydraulic, manual, or CNC, depending on how frequently it is used, how many parts are produced annually, and how thick the pieces are. The most effective machinery for stamping sheet metal is hydraulic CNC presses. They can produce stamped metal components without the machinist's involvement if they have automatic sheet feeding equipment.

Common Sheet Metal Stamping Processes

The sheet metal, die, and press machine are the only three real parts in sheet metal stamping, albeit each part may go through several processes to reach its final shape. The following information covers typical procedures that could happen during metal stamping.

Forming

Pushing flat metal into a different shape is called "forming." Various techniques can be used, depending on the part's design needs. A series of procedures can change the shape of the metal from a relatively simple one to a sophisticated one.

Blanking

Blanking is the simplest way for stamping sheet metal. It begins with feeding the sheet or blank into the press, where the die is then used to cut out the desired shape. The completed item is referred to as a blank. The blank can either move on to the subsequent stage of forming or be a fully finished blank, which is the desired part.

Drawing

Vessels or substantial depressions are made during the drawing process, which is a more challenging task. Then, tension is used to accurately draw the material into a hollow to change its shape. Although the substance may enlarge while extracted, specialists strive to minimize stretching to maintain the substance's integrity. Drawing is frequently used to create culinary items, sinks for vehicles, and oil pans.

Piercing

In contrast to blanking, piercing uses the material surrounding the edge of the perforated area instead of blanks. As an example, visualize cutting circles of rolled-out dough into biscuits. When blanking, the biscuits are saved; however, with piercing, the biscuits would be thrown away, and the hole-filled remains would be used to create the desired effect.

Materials Used With Sheet Metal Stamping

While almost any metal, even gold, can be stamped, sheet metal is the most typical type. The required type of part and desirable attributes, such as corrosion- and heat resistance, determine the type of metal utilized. Parts made of stainless steel, low- and high-carbon steel, aluminum, titanium, brass, bronze, copper, Inconel®, nickel alloys, and many more can be produced through sheet metal stamping.

Applications of Sheet Metal Stamping

During the stamping process, sheet metal is shaped into intricate pieces with the aid of highly specialized computer-aided drawing and production applications. As a result, stamping sheet metal quickly and efficiently yields excellent, long-lasting, heavy-duty products. In addition, because of how accurate they are, their results are typically more trustworthy and consistent than manual machining.

Parts for the automotive, renewable energy, medical, industrial, aerospace, hardware, and home improvement industries are made using sheet metal stamping. This list of industries is by no means complete. However, sheet metal stamping is widely used and in high demand in many industries.

Advantages of Sheet Metal Stamping

• lower die costs
• high precision and accuracy
• Sheet stamping offers a quick turnover.
• lower secondary costs
• extensive automation in comparison to other processes
• Compared to conventional procedures, metal stamping dies are typically less expensive to make and maintain.
• Compared to other metal manufacturing processes, secondary expenditures for cleaning and plating, for example, are less.
• Stamping equipment is generally simple to automate, and advanced computer control programs can increase precision, speed up production, and shorten turnaround times.
• The high degree of automation also drives down labor costs.

Disadvantages of Sheet Metal Stamping

The increased cost of presses is one drawback of stamping; another is that specialized metal stamping dies require a longer pre-production process and must be purchased or made.

Changing the dies might also be challenging if a design modification needs to be made during manufacturing.
