Product Overview
Deep drawing forms a flat blank into a hollow shape by drawing it through a die with a punch, often in several successive stages. The result is a seamless component with no welded joint, which is why deep drawing is used for pressure containing and liquid containing parts where a weld would be a weak point.
Deep drawing rewards experience more than most stamping processes, because blank size, draw ratio, lubrication and inter stage annealing all have to be right or the part tears or wrinkles.
Key Benefits
Seamless Construction
No welded joint, so there is no seam to leak or fail under pressure.
Material Efficiency
A single blank becomes the whole part, with little scrap beyond the trim.
Work Hardened Strength
The drawing process work hardens the walls, adding strength without extra thickness.
High Volume Consistency
Once the process window is set, parts repeat closely across long runs.
Application Scenarios and Who It Is For
- Cups, cans and cylindrical shells
- Enclosures and housings
- Automotive fluid and filter components
- Appliance and cookware components
- Electrical shielding cans
If your application is not listed, send the drawing anyway. Most of our work arrives as a part nobody else wanted to quote.

Manufacturing Process and Quality Control
Drawing Review
Our engineers review manufacturability, confirm tolerances and raise anything in the drawing that would cause a problem before production starts.
Sample Approval
Free samples are offered prior to mass production, with first piece inspection recorded against your drawing.
Production Control
In-process inspection at a set frequency during the run, using the coordinate measuring machine and gauges in our inspection room.
Surface Treatment
Anodizing, sand blasting, polishing, electroplating and powder coating applied in house after deburring and cleaning.
Final Inspection
The finished lot is checked against the drawing before packing, with certification issued for the stages you require.
Packing and Delivery
Protective packing appropriate to the part, dispatched within the agreed delivery date.
Customization Options
- Material — specify a grade from our catalog, or describe the function and our engineers will recommend one.
- Tolerance — standard machining tolerance is 0.005 to 0.01 mm; tighter callouts are discussed at quotation.
- Surface finish — anodized, sand blasted, polished, electroplated, powder coated or as machined.
- Marking — laser engraving and CNC engraving for part numbers and logos.
- Quantity — from a single prototype through to long production contracts.
- Certification — certification provided at each stage on request.

Product FAQ
How deep can a part be drawn?
It depends on the draw ratio for the material and the number of drawing stages. Send the part drawing and we will tell you how many stages it needs.
Will the wall thickness stay constant?
No. Wall thickness varies through a drawn part by nature of the process. If your drawing specifies a constant wall, tell us so we can discuss it before tooling.
Can drawn parts be plated?
Yes, plating, powder coating and polishing are available in house.
How do I order this part?
Do you offer free samples?
Yes, free samples are offered prior to mass production so you can confirm the part before committing to a run.
