Deep Drawn Metal Stamping

The deep-drawn metal stamping is a machining technique where the flat blanking strips achieve specific shapes. They are punched into different open hollow components or decrease hollow parts’ diameter and improve their height. Numerous shape options are fulfilled using a deep-drawn stamping process. That includes stepped, spherical, box-shaped, cylindrical, tapered, and other complex shapes. Moreover, this process plays an essential role in the production of various industries, like Medical, Electrical, Automotive, and Aviation.

Process of Deep Drawn Metal Stamping

KDM performs the following deep-drawn metal process.

  1. Reviewing Designs: KDM engineers review the component designs, ensuring accurate details for the deep-drawn stamping process.
  2. Press Selections: Our expert engineers also identify the machine sizes and caliber, suitable for material and component measurements.
  3. 3D Virtual Prototyping: This process catches custom design problems before starting a manufacturing procedure.
  4. Machine Setup: After reviewing parts’ dimensions, die and punching equipment are set up.
  5. Deep Drawing Procedure: The metal sheet materials are placed and secured into the die. Pressing with activated force is performed and repeatedly done until the desired shapes are achieved.

Deep Drawn Metal Stamping Factors

When operating deep-drawn stamping for your manufactured metal products, you will need to consider the following factors:

  • Minimized Material Waste: The deep drawing stamping process consumed more base material amount than other metal techniques.
  • Measurements: It is also essential to know the precise dimensions, thicknesses, and measurements of forming metal parts.
  • Draft & Tapering: There are unavoidable draft and tapering occurrences during the process. And this should be considered during the primary designing phase.

Which metal is best for deep-drawn metal stamping?

Deep-drawn stamping is suitable for high elongation materials. Sheet metal is preferred for raw material processing, but other metal materials are also used, including:

  • Alloy
  • Nickel 
  • Aluminum
  • Cold-rolled steel
  • Stainless steel
  • Copper 
  • Iron
  • more
Why use a deep-drawn metal stamping ratio?

The Deep-drawing ratio can be computed roughly as DR Db/Dp. Factors such as anisotropy, depth, punch and die radius, and black substance have an impact on the actual limits of the drawing volume.

How is the Deep-drawn metal stamping force calculated?

Spdt, d, and t are the diameter and thickness of the punch or cup and the blank, respectively. F is equal to Spdt. The term “spdt” refers to the tensile strength of the material being drawn, expressed in psi. As a result, the stamping force is calculated by multiplying the cup wall’s cross-sectional area by the pressure.

What is the purpose of Deep-drawn metal stamping?

Deep-drawn metal stamping is ideal for sheet metals.

The processed sheet metals can be found in things and items we use daily with deeply drawn features. That includes chairs, lamps, sink metal frames, and other furniture and equipment. KDM widely used deep drawing technology due to its exceptional advantages.

How can wrinkles be prevented in a deep-drawn metal stamping?

Wrinkles in deep-drawn metal stamping can be a very complex defect that requires in-depth testing and analysis. Here are some ideas on how to avoid it:

  • To prevent any areas from arching, wrinkling, and distortion, a suitable pressing device must be set.
  • For the material flow to be altered, a draw bead must be applied to the pressing surface.
  • To finish the stamping part and prevent wrinkles, use the proper ejector pressure.
