Deep Drawing
Deep Drawing is a metal forming process used to create three-dimensional shapes from flat metal sheets by drawing the material into a die. This technique is particularly useful for producing parts with deep cavities or complex geometries, such as cans, enclosures, and automotive components. Deep drawing is known for its ability to produce seamless, durable, and high-precision parts, making it a popular choice in various industries.
There are many kinds of deep drawing, and the location of the deformation zone, the nature of the deformation, the distribution of the deformation, and the stress state and distribution law of each part of the blank are essentially different due to the different geometric characteristics. Some common stretching methods include rectangular drawing, mound drawing, flanged hemispherical drawing, flange drawing, edge drawing, and deep drawing.
The choice of material is also crucial when manufacturing deep drawing parts. Commonly used materials include carbon steel, alloy steel, and stainless steel. Because of its good plasticity and toughness, carbon steel is often used in the drawing process of building structure, machinery manufacturing, automobile manufacturing and other fields; alloy steel has higher strength and hardness due to the addition of appropriate alloying elements, and is suitable for occasions with high requirements for material strength; stainless steel is especially suitable for humid and corrosive environments with its excellent corrosion resistance.
We have the capabilities to produce complex parts with draws up to 3” deep and 8” in diameter. Using CAD/CAM drawing system, we converts flat metal blanks into complex cylindrical, rectangular, square, or multi-faceted shells. With our in-house tooling, up to 220 ton oil hydraulic press, enables us to produce draws with material thickness of .005″ to .138″.
