Deep Drawn Metal Forming
What is Deep Drawn Metal Stamping?
Deep drawing is a form of metal stamping where the depth of the draw is typically greater than its diameter. In practice, it is possible to produce long, narrow, cylindrical parts with a length that is significantly greater than the outside diameter of the part. This process is used to create a wide range of metal parts, from small precision components to larger industrial products.
The deep drawing process involves placing a flat piece of sheet metal over a die and then using a punch press to force the metal into the die cavity. The shape and depth of the final part are determined by the shape of the die. This method allows for complex shapes with tight tolerances to be produced consistently and efficiently.
Whether It’s A New Or Existing Product, Your Final Design will perform To The Highest Standards
Our Bliss, Waterbury and Ferracute presses enable us to create high quality, tight tolerance parts of long lengths and small diameters from: aluminum, brass, copper, stainless steel, cold roll steel, tin plate and various precious metal alloys. We use these materials to create parts for a variety of industries, including automotive, aerospace, electronics, and medical devices.
Deep drawn metal stamping is often used for producing parts with high strength and durability. The process results in a strong part with minimal material waste as the metal is stretched rather than cut. This makes it a cost-effective solution for creating complex shapes that require specific strength or rigidity.
Additionally, deep drawing can also be used to produce hollow parts by using multiple draws on a single piece of sheet metal. This allows for even more intricate designs and can save time and money by reducing the need for welding multiple pieces together.
How Deep Drawing Metal Stamping Works
Deep drawing metal stamping is a manufacturing process used to create cylindrical or box-shaped parts from sheets of metal. This technique involves pressing a flat sheet of material into a die cavity, creating a hollow shape with walls of uniform thickness.
How the Process Works:
- Blank creation: Flat material in coil form is automatically fed into a blanking station where a flat cylindrical blank is formed.
- Material transfer: The blank is then automatically transferred through a series of stations consisting of a unique punch and die combination in each station. This sequence of punch/die combinations draws the part one step at a time to avoid material failure.
- Punch movement: At each station, the punch is moved down onto the material with immense force, pushing the material into the die cavity creating a hollow shape.
- Shape formation: Depending on the shape of the final part, one or more dies may be used to form complex shapes.
- Special features: Additional operations may be integrated into the sequence of stations including bead rolling, threading, notching, coining, piercing, and reverse drawing which can allow for several additional geometric possibilities.
- Part ejection: Once the deep draw process is complete, excess material is trimmed off and the finished part is automatically ejected from the press.
Benefits of Deep Drawn Stamping
One of the main benefits of deep drawn metal forming is low cost of production/operation per part because of:
- High volume of production due to high capacity and high speed of the press.
- The finish doesn’t require further processing, and secondary operations such as beading, notching, chamfering and piercing can be performed within the deep draw tooling.
- The absence of welding or joining processes, which can add costs and increase the risk of part failure.
- The high precision and accuracy achieved in deep drawn parts, reducing the need for further machining and finishing operations. This not only saves time and money, but also ensures consistent quality in the final product.
In addition to these cost benefits, deep drawn metal forming also offers other advantages such as:
Versatility: Deep drawing can be used to produce a wide range of shapes and sizes with varying thicknesses. This versatility allows for the production of complex designs that may not be possible with other manufacturing methods. It also makes deep drawn parts suitable for use in various industries, from automotive and aerospace to medical and consumer products.
Material options: Deep drawn metal forming can be used with a variety of materials including stainless steel, aluminum, copper, brass, and even certain precious metals. This allows for flexibility in material selection based on the specific requirements of the part.
Strength and durability: The process of deep drawing involves stretching and shaping the metal into its final form without compromising its strength or structural integrity. This results in parts that are strong and durable, making them ideal for use in applications that require high mechanical properties.
Smooth surface finish: Deep drawn parts have a smooth and consistent surface finish, which is important for many applications such as food packaging or medical devices where a clean and hygienic surface is necessary. This also eliminates the need for any additional finishing processes, saving time and cost.
Production efficiency: The high speed and capacity of deep draw presses allow for efficient production of large quantities of parts in a short amount of time. The use of automated feeding systems further enhances this efficiency by reducing manual labor and improving overall productivity.
In conclusion, the benefits of deep drawn metal forming extend beyond just cost savings to include versatility, material options, strength and durability
Best Metals For Deep Drawn Stamping
Choosing the right type of metal for deep drawn stamping is crucial to ensure high-quality and cost-effective production. Some of the best metals for deep drawn stamping include:
- Aluminum
- Brass
- Stainless steel
- Copper
- Bronze
- Steel alloys
- Titanium

- Specialty Metals such as Alloy 79
Essentially, any metal that can be rolled into sheets should be suitable for deep drawing. Ductility, cold workability, and hardness are some of the key properties that impacts deep drawing.
It is also important to consider the effect that cold working from the deep draw process will have on the metal including work hardening. A secondary heat treating process may be required to bring the metal to the desired final hardness.
Deep Draw Stamping Enhancements
Nickel and chrome plating not only enhance the aesthetic appeal of metals but also significantly increase their durability and resistance to corrosion. This makes them popular choices for a wide range of applications, from automotive parts to household appliance
Powder coating provides a durable and environmentally friendly finish for metals, offering superior resistance against corrosion, scratches, and fading. Its versatility allows for a wide range of color options and finishes, catering to diverse aesthetic preferences and industrial needs.
Electrostatic applied lacquer utilizes an electric charge to adhere the paint to the metal surface efficiently and evenly. This method ensures a smooth, high-quality finish with no drips or runs.
Metal polishing enhances the surface quality of metals, producing a smooth, reflective finish. It removes imperfections and prepares the metal for further finishing or application.
We offer other finishing services including, but not limited to:

Types of Deep Drawing Metal Stamping
There are three main types of deep drawing metal stamping:
- Single-Action Press: In this type of press, only one punch is used to create a single-shaped part.
- Double-Action Press: This press uses two punches, one for forming and one for redrawing, allowing for more complex shapes.
- Compound Die: A compound die has multiple die cavities and can perform multiple operations, such as cutting and bending, in one pressing. This type of stamping is more efficient and produces less scrap material.
