The benefits of stainless steel deep drawing

Compared with metal spinning and welding operations, the cycle time for each part is shorter.

The integral part can be made of a sheet or plate.

A fairly uniform material thickness can be achieved in the stainless steel shape.

Can avoid welding and produce deeper parts.

Cost saving techniques for stainless steel deep-drawn parts

During cold forming, stainless steel tends to undergo strain hardening, so minimal deformation is ideal.

The design should minimize the ratio of depth to diameter (or length and width) to avoid the need for a stress relief process.

Generally, before stress relief is required, the limit is a reduction of 2, that is, the ratio of depth to diameter in 304 or 316, which does not exceed 1:1 in thicker materials.

Starting from approximately 14 gauge (0.074 inches / 1.75 mm) thick material, stretchability decreases as metal thickness decreases

What is Deep Draw / Deep Drawing?

Deep drawn stainless steel parts is the process of forming a metal part from metal sheet stock, also called a metal blank, and requires a punch, die and blank holder.

The metal forming process is considered deep drawing if the depth of the item created is equal to or greater than its radius. Therefore, deep drawing stainless steel parts is used to fabricate parts and products that are deeper than metal stamping can accommodate. In fact, when the specifications and/or selected metal limits the part depth on a single draw, a deep drawn metal part can be redrawn to achieve the final seamless form.

Deep drawn stainless steel parts, also known as drawing, stretching, calendering, etc., refers to the use of a die to punch a flat blank of a certain shape obtained after punching into various open hollow parts or reducing the diameter of the open hollow blank to increase the height Kinds of machining processes. The deep-drawing process can be used to manufacture cylindrical, stepped, tapered, spherical, box-shaped and other irregular-shaped thin-walled parts. Cooperate with other stamping and forming processes such as flanging, bulging, flaring, necking, etc., it can also manufacture parts with extremely complicated shapes. Therefore, the drawing process occupies a very important position in the production process of industrial sectors such as automobiles, airplanes, tractors, electrical appliances, instruments, and electronics.
