Metal stamping is a type of manufacturing process used to transform sheet metal into specific shapes. Many types of metal stamping processes exist depending on the needs of each application, including deep drawn stamping and progressive die stamping. In this post, we’ll provide a breakdown of how deep drawn stamping and progressive die stamping work, along with when to use them.
The Deep Drawn Stamping Process
Deep drawn stamping forms various types of hollow axisymmetric components out of metal sheets. The name “deep drawn” comes from the fact that the end products typically feature depths that exceed their diameter. Most of the shapes that this process forms feature a cylindrical shape, but it’s also possible to form box-shaped products through deep drawn stamping. A wide variety of applications use this process to form many types of products, including baking pans, auto parts, casings, sinks, and plumbing fixtures.
The process starts with the placement of the metal sheet on the system’s forming die. A blank holder then applies compressive force to the sheet to hold it in place. At this point, a punching tool applies an axial force to the metal, which causes it to deform and draw into the die cavity to form the final shape.
This process offers a number of benefits, such as:
- Increased speed due to the ability to simultaneously perform draws in multiple stations
- Reduced tooling costs
- Maintained tolerances and high repeatability
- Durable rolled metal parts featuring a cohesive and elongated grain structure
- The ability to work with a wide range of metals, including stainless steel, copper, aluminum, and more
The Progressive Die Stamping Process
Progressive die stamping involves several workstations that perform different operations on the same part. The part is carried by a stock strip through each workstation until it is completed.
The process begins when operators place the die into a stamping press. The die then opens as the stamping press moves upward. The die closes as the stamping press moves back down. Metal travels through the die at certain increments as the press makes each stroke. In the process, the stamping die modifies metal by either bending, cutting, shaving, lancing, coining, drawing, or embossing the workpiece.
Once the die closes, it performs the necessary operation on the metal to form one or more parts. These parts may be either connected to a carrier strip or separate from one another.
The progressive die stamping process comes with several key benefits, including
- The ability to produce components at a rapid pace
- The capacity to run multiple cutting or forming operations simultaneously
- High press tonnage
- Fast set-up
- The ability to produce multiple parts per press stroke
- Maintained control over part location during the stamping process
- Maintained tolerances
