What Types of Deep Drawing Parts Are There and What Are Their Functions?

Deep Drawing Parts are hollow parts made of metal sheets through one or more deep stamping of a drawing die. The notable feature is that the depth is greater than the diameter (or width). Common types and functions include:

Cylindrical parts (such as cans, thermos cup liners): mainly used for container products, requiring uniform wall thickness, good sealing, able to withstand internal pressure or provide storage space, and have both lightweight and strength advantages.

Square/rectangular parts (such as battery shells, some electrical appliance shells): commonly seen in the shell/containment structure of electronic equipment or industrial components, which facilitates the regular arrangement of internal components, while providing mechanical protection and appearance flatness.

Special-shaped parts (such as car lampshades, complex curved surface covers): adapted to the streamlined or functional styling requirements of specific products (such as automotive parts, home appliance panels), with both aesthetics and spatial matching.

Flange parts (drawn parts with flanges, such as pipe joint seats): flanges provide connection or reinforcement surfaces (such as bolt fixings, welding interfaces), suitable for pipeline systems or parts to be assembled.

Stepped parts (barrel-shaped parts with multi-level diameter changes, such as cylinder housings): meet the requirements of multi-layer structures or segmented functions (such as liquid storage, segmented installation), and one-step molding reduces welding or assembly processes.

Deep Drawing Parts are widely used in automobiles (fuel tanks, oil pans), home appliances (liners, shells), packaging (metal cans), electronics (shielding covers, battery shells) and other fields with the advantages of one-piece molding, high material utilization, good strength, and strong sealing, achieving lightweight, efficient production and functional integration.

Deep Drawing Parts widely serves modern industry with its unique process advantages. This type of parts greatly improves the material strength through cold deformation, achieving the same pressure-bearing requirements with thinner materials, and significantly reducing the weight of the product. In the automotive field, fuel systems, exhaust components and transmission system housings rely on their high-precision sealing; the packaging industry is used in airtight tanks (such as spray cans and food cans) to give full play to their anti-penetration barrier function. Sterile containers in medical devices, home appliance liners and hardware appliances (such as stainless steel cookware) also benefit from the hygiene and durability of their one-piece molding.

The high efficiency of the production process is particularly outstanding. A single stamping can complete complex geometric shapes, and with the help of automated production lines, a high-speed output of dozens of pieces per minute can be achieved. At the same time, the material utilization rate of the deep drawing process generally exceeds 70%. Through reasonable layout, the scrap rate is greatly reduced, and the cost is effectively compressed in large-scale manufacturing. It has become an irreplaceable core technology for the manufacture of precision metal shells.
