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
The ability to produce multiple parts per press stroke
Maintained control over part location during the stamping process

Metal fabrication is a key service that is applicable to a wide range of industries, including aerospace. The critical and often complex nature of aerospace components necessitates precision. These components are crafted through a variety of metal fabrication services, from drawing and forging to welding and extrusion. In this blog, we’ll cover how metal fabrication works and how it serves the aerospace industry.
A Quick Overview of Metal Fabrication
Industrial metal fabrication is essentially any process that cuts or forms raw metal into a desired stock or custom product. These techniques can be used on nearly any type of metal, though steel and stainless steel, copper, aluminum, nickel, and brass are some of the most common. Metal fabrication services are an efficient, cost-effective way to produce a high quantity of identical components.
There are different metal fabrication processes, and the one you use depends on several factors such as the type of metal you’re working with, the desired size and shape of the component, and any particular characteristics the component requires. In many cases, you can combine multiple processes to achieve the desired final product. Metal fabrication processes include:
Drawing. This process involves forcing molten or sheet metal through a die to create the desired shape. Deep drawing applies specifically to parts that have depths that are greater than their diameters.
Forging. Whereas drawing uses tensile force to shape the metal, forging relies on compressive force. The metal is hit with a hammer or die to achieve the desired shape.
Extrusion. This technique is common for creating pipes and other cylindrical components.
Punching. This is the process of creating holes or indentations in a piece of sheet metal for decorative or functional purposes.
Welding. There are many types of welding, all of which are used to join similar or dissimilar pieces of metal together via heat and pressure.
Drilling. Drilling is a standard process for creating circular holes.
Milling. In this common subtractive manufacturing process, a milling machine or router is used to remove bits of material to create the desired shape.
Turning. Common for creating cylindrical components, a piece of metal is turned on a lathe while being shaped with a cutting tool.
Aerospace Metal Fabrication
Aerospace components must meet stringent standards for quality, reliability, and safety. Metal fabrication processes – especially when carried out by a top-notch fabricator – allow for the complexity, repeatability, tight tolerances, and durability these products require for use in exceptionally harsh conditions. Titanium, stainless steel, aluminum, and carbon steel, along with specialty metals and alloys, are commonly used in aerospace metal fabrication to produce components like:
Switches and relays
Oxygen generation and pressurization systems
This is only a sample of the wide array of components that can be produced through precision metal fabrication processes. Regardless of the exact part you are looking to bring to life, it is important to choose a metal fabricator that fits the following criteria:
Offers transparency and regularly-communicated updates throughout the entire fabrication process (i.e. turnaround time)
Goes above and beyond in terms of customer service before, during, and after fabrication. For instance, does their team offer design & engineering support and recommendations?
Upholds certifications relevant to aerospace requirements and follows stringent quality control and, ideally, has a quality assurance department in-house
