Good Edge Quality
With Sheet Metal Blanking
We use this efficient metal fabrication technique that involves using pressed steel rule dies to punch out parts from sheet metal coils or blanks.
introduction
Sheet Metal Blanking Services
Precision. Accuracy. High Quality.
Blanking can stamp out parts very quickly and at a low cost per part compared to other methods through fast cycle times and efficient material usage.
DEK is an industry leader in precision sheet metal blanking and fabrication services. With over 20 years of experience, we have honed expertise in efficiently blanking a wide range of materials, part sizes, and production volumes. We use finely tuned processes, and we achieve extremely tight tolerances down to ±0.005mm for superior part accuracy and consistency. Our expertise ensures every blanked part meets your exact specifications from our ISO 9001-certified facilities.
Through large-scale coil-fed blanking presses and quick die changeovers, we can rapidly deliver pristinely blanked parts at very attractive pricing, maintaining a low cost per piece, even at high quantities. Small and large part sizes can be expertly accommodated.
Our Highlights
Precision and Accuracy
The process consistently delivers parts within tight tolerances thanks to sharp dies pressing into the sheet metal. Complex shapes are possible.
Quality and Minimal Secondary Work
The cut edges are smooth and clean, often eliminating part deburring. Some minor hole punching, bending, or welding may be needed before parts are ready for assembly or finishing.
Flexibility
Blanking works for many metals, different sheet thicknesses, small to large part sizes, and production runs from prototypes to high volumes. Minimal setups allow easy changeovers.

TECHNOLOGY OVERVIEW
About Sheet Metal Blanking
What is Sheet Metal Blanking?
Sheet metal blanking is a highly efficient metal fabrication technique that uses pressed steel rule dies to punch out precise, repeatable parts from sheet metal. In a blanking press, coiled metal or metal sheets are fed into specialty dies that press into the material, cutting multiple parts per stroke with tight dimensional control. Blanking works very fast, outputting high volumes of finished stampings for low cost due to the process's high material usage and quick cycle times. The parts produced require little to no secondary processing since the cut edges are smooth and clean. Blanking excels at making flat or simple-formed geometries out of steel, stainless steel, aluminum, copper, and brass.

FAQ
Sheet Metal Blanking Buying FAQs
Blanking works for low to medium carbon steels, stainless steel, aluminum, brass, copper, and more. Hardness and ductility determine suitability.
We can handle parts from less than one inch to 20 inches or more in dimension. Thicknesses range from 0.005” to about 1⁄4”, though thinner or thicker is also possible.
Flat forms tend to be simplest, but bent, contoured, and complex shapes are also achievable depending on the blanking press depth and tooling design.
Fineblanking can hold incredibly tight tolerances down to ±0.002”, though ±0.005” to ±0.02” is more typical for standard blanked parts.
Specialized multi-ton steel rule dies made of tool or stainless tool steel are the most common. We may also utilize urethane stripper pads.
We can provide quotes within 6 hours.
We also provide off-press fabricating services like hole punching, forming, welding, grinding, and more to deliver finished components.
Initial specifications would include material type and thickness, annual usage estimate, a technical drawing, and desired lead time—any size, tolerance, or finish requirements.
