Deep Drawn Components
Deep drawn parts formed by radially drawing a sheet metal blank into a forming die, turning flat material into a cavity, cylinder or cup. The process produces intricate and precise components with high repeatability, and is used for parts that would otherwise need welding or machining from solid.

Product Overview
Deep drawn parts formed by radially drawing a sheet metal blank into a forming die, turning flat material into a cavity, cylinder or cup. The process produces intricate and precise components with high repeatability, and is used for parts that would otherwise need welding or machining from solid. Material selection is central, since the blank has to stretch without tearing.
Key Benefits
- Produces a seamless cavity or cylinder without a welded joint
- High repeatability across large production quantities
- Thinner walls and lighter parts than machining from solid
- Suitable for aluminium, stainless steel, brass and titanium
- Secondary operations such as welding and assembly available on the same order
Problems It Solves
- Welded assemblies that leak or fail at the seam
- Machined parts that waste material and take too long in volume
- Wall thickness that cannot be achieved by casting
- Parts that must be identical across very large quantities

Customisation Options
What Can Be Varied
- Part geometry developed with draw ratio limits in mind
- Material and temper selected for formability
- Number of draw stages set by the depth required
- Trimming, piercing and secondary operations
- Surface finish and coating
Compared With The Alternatives
| Welded fabrication | A deep drawn part has no seam to leak or crack, which matters most in pressure and fluid applications. |
|---|---|
| Machining from solid | Machining suits low volumes and thick walls; deep drawing is far cheaper per part in volume and produces thinner, lighter components. |
Use Guide
- Discuss corner radii and draw depth early, since both decide whether the part can be formed at all
- Allow for material thinning at the corners when specifying wall thickness
- Confirm material temper, not only the alloy
- Plan trimming allowance into the blank size
Questions
Questions Buyers Ask About This Product
What shapes can be deep drawn?
Cavities, cylinders and cups formed from a flat blank, with intricate detail possible within the limits of the material.
Which materials can you draw?
Aluminium, stainless steel, brass and titanium among others.
How deep can a part be drawn?
It depends on material, thickness and diameter. Deep parts are produced in several draw stages, and we will tell you at quotation how many the geometry needs.
Is deep drawing suitable for small quantities?
It is a tooled process, so it suits volume production. For small quantities we will usually suggest another route.
Can drawn parts be welded and assembled?
Yes, welding and assembly are available as secondary operations.
