Deep drawn parts
Lesjöfors is one of the leading deep drawn components manufacturers, producing deep drawn parts, components, and pressings with tight tolerances. Each one has consistent wall thickness and a smooth surface for demanding environments.
In our global facilities, we use advanced progressive and transfer tooling to create complex metal parts with depths greater than their diameter, delivering precision shapes through multiple redraws or thinning drawing.

What are deep drawn parts?
Deep drawn parts are hollow, cup-like, or enclosed components. They are made by pulling a flat metal blank into a die cavity with a punch. This reduces the diameter while increasing the height through a series of controlled drawing steps.
The process is ideal for creating seamless metal stampings. These can have straight or tapered walls with a consistent wall thickness.

Custom deep drawn parts
Every application presents its own challenges. Our custom deep drawn stampings are made to match the target shape, draw, ratio, wall thickness, and tolerances. Material choice and forming steps are planned for both performance and cost.
With decades of industry experience, we ensure that each deep drawn part is not only functional but optimized for its intended use. Global production ensures reliable lead times, even at scale.
Types of deep drawn parts
There are several common deep drawn parts and process variants suited to different shapes and requirements.
Cylindrical cups and sleeves
Cylindrical shells have straight or tapered walls. They’re formed in multiple stations to control the draw ratio and create smooth, even surfaces. They are used for sealing, shielding, or flow applications.
Conical and stepped forms
Conical or stepped deep drawn components use staged drawing to control forming; this solution can decrease thinning or prevent cracking. It also allows for complex shapes with precise transitions.
Non-round and rectangular shells
Non-circular parts use transitional shapes. Multiple redraws spread forces evenly across the corners. This protects edges from cracking while maintaining tight tolerances.
What is deep drawn stamping, and how does it work?
Deep draw metal stamping holds a flat blank on a die. A punch pulls the material into the cavity under radial tension and tangential compression. The diameter decreases, and the height increases over successive draw stations until the final shape is achieved.
The number of draws depends on the material, thickness, corner radii, and target depth-to-diameter ratio.
Advanced deep drawn part manufacturing
As trusted deep drawn manufacturers, Lesjöfors uses progressive and transfer-press technology. This guides parts securely and efficiently through deep stations, allowing for deeper drawing, tighter tolerance and better quality.
- Multi-station drawing and reduction for complex geometries.
- Transfer press handling for precise part control during forming.
- Tooling engineered for repeatability and throughput in production.
Deep drawn parts materials
Common materials for deep drawn metal stampings include stainless steel and aluminum. Brass, copper, and cold-rolled steel are also widely used. And recently, clad material is also used in the deep drawing field for some special applications.
The choice depends on drawability and corrosion resistance. Strength, temperature performance, conductivity, and cost also play a role in each application.
