Deep Draw Metal Stamping is a type of sheet metal forming that involves radially drawing flat sheet metal into a die to create the desired components. The name “deep draw” refers to the components involved, which exhibit greater depth than width. We create these depths by redrawing the component through a series of dies, further reducing width with increasing length. It is also common for components to be deep draw partially to create various diameters throughout the part. This process reduces costs in comparison to turned parts, which need more materials overall.

Deep Drawing versus Stamping | What’s the Difference?

Deep drawing is similar to stamping, as both processes are used to shape and form sheets as needed. Wedge Products is among top deep draw metal stamping manufacturers who understand the number of drawing methods that can be used for metal forming.
The main difference between deep drawing versus stamping is the tools that are needed. In stamping, the tools used are designed to fracture a sheet into a shape. However, these tools are limited in that they cannot create deformation. Drawing tools are used for deformation which means that they are radiused, while stamping tools are known to have sharper edges.
In addition, tools used for deep draw stamping clamp the outer edge of the blank in place while the center is deformed. Drawing tools also have a greater punch-to-die clearance than those used in metal stamping.

Deep Draw Forming Methods

Deep drawing also involves other forming methods and techniques within the press. These methods include:

  • Beading: Displacing the material to create smaller or larger diameters than the part’s original diameter.
  • Bottom Piercing: Cutting a round or shaped section of metal from the draw component.
  • Bulging: Forcing part of the components diameter to extend from the original shape.
  • Coining: Displacing the material for the formation of specific shapes in the component.
  • Curling: Rolling metal under a curling die to form a rolled edge. Extruding: Once a pilot hole is created, a punch with a large diameter pushes through and causes the metal to increase in length.
  • Ironing: Thinning the walls of the components.
  • Necking: Reducing a section of the component to a smaller diameter than the rest of the part.
  • Notching: Cutting a notch into the open end of the part with a round, square or other shape.
  • Rib Forming: During the drawing process, rib forming creates an outward or inward protruding rib on the part.
  • Side Piercing: Piercing holes in the sidewall of the draw component. Shape depends on the component’s specifications.
  • Stamping: Most commonly used to add identification to the part such as a supplier name or product number.
  • Threading: Forming threads into the component with a wheel and arbor.
  • Trimming: Cutting away metal that was necessary for drawing the part from the finished component.

Understanding Deep Draw Stamping

The deep draw metal stamping process is essentially the process used to form sheet metal using compression and tensile conditions. The sheet metal is forced into a cavity and then produces a shape cup or cylinder that can be round, irregular, or closed bottomed. As a metal sheet undergoes deep draw stamping, it is dragged over the die radius and forced down into the die, thus entering a plastic state. When the sheet is compressed it is done so under very controlled conditions that use specific punch speeds, punch and die radius, and lubrication. It takes deep drawing services experts to safely perform this process.

After the metal sheet passes through the die, it forms a vessel that’s square or rectangular. The name “deep draw” actually refers to the components involved that have a greater depth than width. The parts formed from deep draw stamping are known to be extremely versatile and are used in the automotive industry, electronics, lighting, and more. For example, some common items that were made using deep drawing services include:

  • Pressure vessels
  • Appliance parts
  • Assembly housings
  • Bushings

Why Utilize Deep Draw Metal Stamping?

There’s a reason deep draw metal stamping has become widely used across industries to create parts that last.

When done well, deep drawing services can increase speed and therefore efficiency. This is because the draw speeds are limited only by the contact velocity of the material, so essentially you can run multiple draws simultaneously. This optimizes cycle types and is especially helpful if you are creating large volumes of parts through deep draw stamping. Deep drawing also lowers costs, and not just because it speeds up processes. The tools that are used for deep drawing services are usually just a set of steel dies that are long-lasting, eliminating the need to constantly replace equipment.

Deep draw metal stamping is also beneficial because manufacturers can use a variety of metals when deep drawing. Common metals include stainless steel, aluminum, and copper, which are all used to create a variety of parts due to their varying properties. The team at Wedge Products has years of experience in working with different metals and can deliver precision parts on time and at a competitive price.

Deep Draw Stamping FAQs

What is deep drawn stamping?

Deep drawing, also known as deep drawn stamping, is a metal forming process extensively used in manufacturing to produce three-dimensional shapes with considerable depth. The process involves the transformation of a flat sheet metal blank into a complex, often cylindrical or box-like structure with a depth greater than its original diameter or size. This method is particularly suitable for creating components like enclosures, containers, and certain automotive parts that require significant depth.

The deep drawing process typically consists of several stages. It begins with the blanking stage, where a flat metal sheet is cut into the desired shape, often circular or rectangular, to create the initial blank. Subsequently, the blank is placed over a die, securely clamped, and a punch descends into the die cavity. This action pulls and shapes the metal into the form of the die, resulting in the creation of the deep-drawn part. In cases where additional depth is required, a redrawing operation may be performed, either once or multiple times, to achieve the final dimensions.

Trimming is the final step in the deep drawing process, where excess material is removed from the formed part to achieve the desired final shape. The advantages of deep drawing include its ability to efficiently produce complex shapes with minimal material waste and excellent structural integrity. This makes it a preferred method for manufacturing various products, including cookware, automotive components such as fuel tanks, and different types of containers.

The versatility of deep drawing allows for the creation of diverse parts, and the design of the die and punch can be customized to accommodate a wide range of shapes and depths. However, successful deep drawing requires careful consideration of various factors, including the material properties of the metal being used, proper lubrication to facilitate smooth forming, and meticulous tooling design to avoid issues such as tearing or wrinkling of the metal during the shaping process.

What is the deep drawn process?

The deep drawing process is a metal forming technique used to create three-dimensional shapes with significant depth from a flat sheet metal blank. It is a cold forming process that involves the use of a die and a punch to deform the metal into a desired shape. The resulting components often have a depth greater than their diameter or original size.

How accurate is deep drawing?

The accuracy of deep drawing is influenced by various factors, collectively determining the precision achievable in forming complex shapes from flat sheet metal. One crucial factor is the precision of the tooling employed in the process. The design and quality of dies and punches significantly impact accuracy, as well-engineered tooling ensures that the metal is shaped precisely into the desired form. The intricacies of the die cavity and the punch play a pivotal role in determining how accurately the metal can be drawn, avoiding distortions or defects in the final part.

Material properties constitute another influential factor in the accuracy of deep drawing. The ductility and thickness of the metal being drawn affect the ease with which it can be formed with precision. Different materials respond uniquely to the deep drawing process, and the selection must align with the desired accuracy of the final product. Additionally, the use of proper lubrication is essential to reduce friction between the metal sheet and the tooling, contributing to the maintenance of accuracy and preventing issues like tearing or wrinkling during the forming process.

The process of deep drawing, when executed with careful consideration and precision, can achieve high accuracy levels. Manufacturers often employ this method for components that require tight tolerances and intricate shapes. Redrawing operations, if necessary, should be executed with precision to maintain dimensional accuracy. Overall, the accuracy of deep drawing relies on the integration of various factors, including tooling design, material selection, lubrication practices, and adherence to best practices throughout the manufacturing process. When these elements are effectively managed, deep drawing can consistently deliver accurate and repeatable results in the production of complex parts.
