What is Deep draw Stamping?

Deep Drawn Stamping is a specialized metal forming process used to create complex parts with a variety of shapes and sizes. This process involves drawing flat sheet metal into a die to form a specific shape.

At Chengli Hardware , we specialize in this process and have over 20 years of experience in the industry.

Advantages of Deep drawing Stamping

  • Faster Production: Deep draw stamping can swiftly create large quantities of components without sacrificing quality by using stamping machines with a range of tonnages, including 45 and 80 tons. 
  • Cost Savings: The ability to save money is one of the deep draw stamping’s most important benefits. Long-term cost savings are possible since the procedure utilizes less material and involves fewer processes than other metal forming techniques. 
  • More Precision: Deep draw stamping can create parts with greater precision, which is crucial in many industrial applications. 
  • Stronger Parts:With consideration for elements like strength-to-weight ratios and stress resistance, our specialists can assist you in making the optimum material and design choices for your particular application.


Challenges of Deep drawing Stamping

  • Tooling Costs: Because deep draw stamping requires specialized tooling, such as dies and punches, there can be significant upfront costs associated with setting up the process. However, these costs can be mitigated by working with a skilled and experienced metal stamping supplier like Chengli Hardware, who can help you optimize your designs and tooling for maximum efficiency and cost savings.
  • Design Limitations: Another potential disadvantage of deep draw stamping is that it may not be suitable for all part designs. Because the process relies on compressing metal sheets into a desired shape, there may be limitations on the complexity and depth of the part that can be achieved. However, our team of experts can work with you to determine the best approach for your specific application, and recommend alternative processes if necessary.

Additional process employed in deep draw stamping:

Deep drawn stamping involves a variety of processes beyond the basic technique of drawing sheet metal into a 3D shape. These processes can be used to further customize and refine the final part.

  • Adding beads, ribs, and flanges to the part’s surface. These raised features can enhance the strength, stability, and rigidity of the part.
  • Bulging:stretches and expands metal in specific areas to create a desired shape or feature. Coining:compresses the metal in a particular area to create a raised or recessed feature, often for decorative or functional purposes.
  • Curling:bending the edges of the metal sheet to form a rounded or curved shape.
  • Dimpling creates a small indentation or depression in the metal sheet, usually for aesthetic or functional purposes.
  • Embossing:raises or recesses a design or pattern in the metal sheet.
  • Extruding is another process that forces the metal through a shaped die to create a continuous profile or shape.
  • Hole forming is used to punch or drill holes into the metal sheet for attachment or assembly purposes.
  • Ironing is a process that compresses the metal sheet to create a smoother and more uniform surface finish.
  • Marking can stamp or laser etch identifying information onto the part, such as part numbers or logos.
  • Necking :narrows the diameter of the metal sheet in a specific area to create a desired shape or feature.
  • Notching :involves cutting small grooves or notches into the metal sheet, often for assembly or attachment purposes.
  • Threading creates threads on the part either by cutting them directly into the metal or by adding a threaded insert.
  • Trimming involves cutting excess material from the edges of the part to achieve the desired final shape and dimensions.

How does deep draw Stamping Work?

Deep drawn stamping is a metal forming process that involves the use of specialized dies and punches to create complex and intricate shapes from flat sheet metal. The process is called “deep drawn” because it involves drawing or pulling the metal sheet into a three-dimensional shape with a depth that is greater than its diameter.
The process typically starts with a blank piece of sheet metal, which is clamped onto a die and then drawn or pulled down into the die cavity using a punch. As the punch presses down on the sheet metal, it creates tension and compresses the metal into the desired shape. This process is repeated multiple times, with the metal being progressively drawn into deeper and more complex shapes until the final part is formed.

Deep Drawing Stamping Design Guidelines

The reasonable design of the deep drawing stamping directly determines the price, quality, and capacity of the product.

 The material type should be carefully chosen depending on the intended use and the part’s needs.We suggest to choose the ductile and easily formed materials, such as steel, aluminum, stainless steel .

Thinner materials are easier to shape, but they may lack the necessary strength. Then the material thickness should be chosen to guarantee that the finished product is strong and durable.


The N and R values are essential characteristics that assist determine the material’s formability. More formability is indicated by higher N and R values.

 To ensure that the final product has the proper dimensions and shape, the blank size and shape should be carefully created.

Part geometry should be tailored to reduce stress concentrations and ensure that the component can be manufactured without tearing or wrinkling.

To guarantee that the part is produced correctly and to reduce the danger of flaws, the press speed should be carefully managed.

 Carefully plan the draw radii to guarantee that the part can be created without tearing or wrinkling.

The draw ratio is the proportion of the blank diameter to the final part diameter. A larger draw ratio necessitates more force and may lead to material thinning.

To reduce the chance of faults in the final item, the die surface finish should be smooth and devoid of imperfections.

 The die temperature should be carefully managed to ensure proper material formation and to reduce the danger of flaws.

 To reduce friction and ensure that the part can be produced without tearing or wrinkling, a suitable lubricant should be used.

 The draw bead height and shape should be carefully planned to guarantee that the part can be produced correctly and that faults are minimized.

Binder pressure should be carefully managed to ensure proper part formation and to reduce the chance of faults.

 The binder deflection should be carefully designed to ensure proper component formation and to reduce the risk of faults.

The standoff height should be carefully selected to enable proper part formation and to reduce the chance of faults.
