How is Sheet Metal Stamping Done

Sheet metal can take any shape when the correct amount of heat and pressure is applied using specialized machinery.

Fremont, CA: Sheet metal stamping is among the most cost-effective methods for rapThousands of pounds of pressure are required to convert the sheet metal effectively. Different types of presses, such as servo-drive, crank-drive, and hydraulic-drive presses, can be used to accomplish this. An uncoiler stores the raw material until it becomes ready to be used in an automated blanking punch press system, such as the 440-ton blanking line. When production is ready, a straightener pulls the coil material from the uncoiler into the ultrasonic loop control (which uses ultrasound to drive the straightener), and a servo-feeder motor draws the material from the loop and into the punch press (tool). The servo-feeder is entirely programmable, allowing for precise control of feed length and pilot release.

Other metal forming operations can happen at the same time as the press brake action. Punching, Blanking, Bending, Coining, Flanging, and Embossing are some of the various operations that can be used.

While stamping can be a cost-effective manufacturing process for both low and high-volume products, it comes with its own set of benefits and drawbacks that vary by application. Faster blanking and forming run rates, more consistent quality owing to a repeatable manufacturing process, and a progressive die assures all forms/features are "Tool Controlled" - no missing features or produced backward components, are some of the benefits of employing a punch press system. Some of its disadvantages are difficulties integrating revisions or part design modifications, longer lead time to the first shipment, and higher initial NRE (Tooling Cost) than other manufacturing processe.
