Deep drawing is a stamping process that applies pressure to a metal flat blank through a die to deform it into an open hollow part (such as a cylinder, box, stepped shape, etc.). DC Metal Machining is a leading manufacturer of deep drawn parts, including cylinders, enclosures and irregular shapes. We’ve earned a reputation for producing highly complex, yet cost-effective, deep drawn parts.
As a leading custom deep drawn parts manufacturer and deep drawn metal stamping manufacturer, we specialize in deep drawn stamping parts and deep draw metal components that deliver excellent surface quality, high material utilization, and cost efficiency for high-volume production. Our deep drawn enclosures and deep drawn housings are trusted in automotive, electronics, appliances, new energy, and aerospace industries.
Capable of forming deep cavities, multiple curved surfaces, and micro-features that are difficult with other processes.
Smooth finish with no visible cracks, wrinkles, or scratches deeper than 0.05 mm .
Reduces scrap by 30–50% compared to machining or welding, lowering overall costs.
Diameter tolerance ±0.05 mm, height tolerance ±0.1 mm, with compound die precision reaching ±0.1 mm.
Verified through hardness, hole expansion, and ductility tests for reliable performance under load.
Single-process, compound, progressive, or continuous dies support prototypes to high-volume runs (up to 800 pieces/hour).
Excessive tangential compressive stress in the flange area will cause material instability and wrinkling;
Solution: Use a blank holder and optimize the blank holder force.
Dangerous sections of the barrel wall (at the corners of the die) are prone to cracking due to concentrated tensile stress;
Countermeasures: Increase the radius of the corners of the punch and die (≥4 times the material thickness), and lubricate the die to reduce friction.
Compensate for elastic deformation through over-drawing or shaping processes.
The first drawing of simple cylindrical parts, simple structure and low cost.
Integrated blanking and drawing, high precision (±0.1mm), suitable for small and medium-sized parts (such as capacitor housing).
Multi-station continuous stamping (trimming → drawing → punching), efficiency up to 800 pieces/hour, used for mass production of automotive parts.
The robot transfers the blank, suitable for large and complex parts (such as automobile fuel tanks).
Deep Drawing can be a multi-draw operation performed on a specially prepared metal blank. The process lends itself to multiple draws using separate draw tools for each draw operation; resulting in a seamless (void-free) part. Our proprietary approach results in a higher quality part and usually eliminates the need to perform X-Ray analysis to confirm void-free fabrication integrity. Once a part has been Deep Drawn it can be followed by secondary operations which range from custom fabricating to light assembly to finishing. Only one purchase order is needed to complete most processes under one roof and under the control of our comprehensive quality assurance program in our clean and efficient facility.
Low carbon steel (SPCC/SPCD), stainless steel (304/316), aluminum alloy (5052/6061) and copper alloy;
The application of high-strength steel (HSS) is increasing, taking into account both lightweight and structural strength
We start with blanks up to 48″ in diameter and make deep drawn parts ranging from ½”-24″ wide with depths up to 24″.
If you haven’t specified a material our expert engineers will help you determine which alloy will best conform to your specifications. We normally source the material for you or we can work with customer-supplied material. We first cut the material into the proper size blanks.
Our engineers take great care to prepare each metal blank according to its properties, which maintains the integrity of the alloy and prevents cracks and tears in the finished product.
Once the blank is prepared, the deep drawn part is formed by drawing the metal blank around a punch as it’s pulled through a die. The edges of the metal blank are restrained by a blank holder or sleeve.
