What Exactly is Deep Drawing

Deep drawing is a kind of metal processing technology that causes a large degree of plastic deformation of metal sheet in the mold, so as to obtain hollow parts or products with large depth and complex shape.

Metal deep drawing is a high efficiency and low cost metal processing process, which is widely used in various industrial fields. The main advantage of this process is its ability to quickly produce parts with complex shapes and precise dimensions to meet the needs of modern manufacturing for product diversity and flexibility. In deep drawing, although a certain amount of mold costs need to be invested in the early stage, these molds usually have a long service life and can support mass production.

What are the components produced by the deep drawing process?

There are many metal deep drawing parts, common including stainless steel POTS, aluminum lunch boxes, various cans, car fuel tanks, lampshades, metal cups, ventilation pipes and so on. In the industrial field, there are some complex shapes of metal shells, mechanical parts, etc., will also be manufactured by the metal deep drawing process.

Compare Deep Drawing and Stamping Processes

Metal deep drawing is an important processing method in the metal stamping process, but the products they produce have significant differences in shape, structure and application fields. Metal stamping usually includes a variety of techniques, such as shearing, bending and forming, and is mainly used to create flat or simple shaped parts. Deep metal drawing, on the other hand, focuses on the plastic deformation of flat metal sheets through a mold to form hollow parts with greater depth and complex three-dimensional structures.

For example, in the automotive industry, the stamping process is often used to produce relatively simple components such as body shells and brackets, while deep drawing is widely used to make fuel tanks, wheel hubs, and other complex parts that need to withstand pressure or loads. These different types of products not only differ in design requirements, but also involve material selection and processing parameter Settings. For example, the deep drawing process has higher requirements for material ductility, so alloy materials with good plasticity are usually selected.
