Laser-Cut and Deep-Drawn Stamped Sheet Metal Parts
These are sheet metal parts made by laser cutting and deep-drawn stamping, such as cups, cans, sensor housings, battery shells, filter caps and EMI shields. Deep drawing forms a flat blank into a seamless hollow shape in progressive or transfer dies. Laser cutting covers flat parts and prototype blanks. They suit buyers moving from prototypes to volume stamped parts.

Manufacturing
How we make this part
Process, material options and inspection for laser-cut and deep-drawn stamped sheet metal parts.
Deep drawing pulls a blank into a die in one or more draws, each one reducing diameter and increasing depth. Parts deeper than their diameter usually need multiple stages and sometimes annealing between draws. For prototypes and very low volumes, we can laser cut and bend or machine a near equivalent, then move to a draw die once the design is fixed and volumes justify the tooling.
Drawing-quality steel (DC04 type), 304 stainless and 1100 or 3003 aluminum all draw well; brass C26800 is used for decorative cans and electrical parts. Stainless steel needs more press force and careful lubrication because it work-hardens. Finishes include zinc or nickel plating, anodizing for aluminum and painting. Secondary CNC machining or tapping can be added to drawn parts.
Drawn wall thickness, height and diameter are measured on the first-off from every die setup, and the edges are checked for wrinkling or tearing. Spot checks continue through the run, with final inspection before shipment. Typical products include sensor and motor housings, cylindrical battery cases, speaker baskets, filter caps, cosmetic cans and EMI shielding cans.
FAQ
Frequently asked questions
How deep can a drawn part be?
In a single draw, depth is usually limited to about half to three-quarters of the diameter, depending on material. Deeper parts use several draw stages, sometimes with annealing between them. We review your part geometry to estimate how many stages the die will need.
Can you make prototypes before building a draw die?
Yes. We can approximate a drawn part by machining from solid, spinning or welding sheet, which is useful for fit checks. Function tests that depend on wall thinning or grain flow should be done with drawn parts from the real tooling.
How do I get a quote for laser-cut and deep-drawn stamped sheet metal parts?
Send a 3D model (STEP or IGES) and a 2D drawing with tolerances, material, finish and quantity through the quote form or by email. An engineer replies within 24 hours on business days with price, lead time and any DFM suggestions.
