A Complete Guide to Sheet Metal Stamping

Stamping of sheet metal is a change of flat metal sheets into different shapes and geometry.
It has wide applications in the component manufacturing of the automotive, aerospace and even household appliances. Moreover, it has also found some applications in electronics manufacturing. So, sheet metal is one of the most important processes in making a wide range of metal parts. It is quite an accurate and cost-effective solution.

Sheet Metal Stamping

This article will discuss all these techniques in detail. Moreover, we will get a deep knowledge of different classifications, step-by-step processes, applications, and challenges of sheet metal stamping.

What Does Sheet Metal Stamping Mean?

The stamping process is also known as pressing. It includes placing flat sheet metals in a press and converting them into a coil or a blank. Here, a tool or die surface attain a specific shape. So, several techniques are used in this stamping process.

What are the Processes Included in Sheet Metal Stamping

Here we will discuss how to stamp sheet metal. So, let’s discuss the process included in sheet metal stamping.

1. Designing

So, the first step of the stamping process is designing. We can use advance technologies, such as CAD/CAM engineering technology. So, these designs must be very accurate. They manage each punch and bend. So, it can maintain the optimum geometry of the metal part. Moreover, they must be clear for optimal part quality. Besides this, a one-tool 3D model has hundreds of parts. In this case, the design process is intricate and time-consuming.

BlankingSo, cut the rough shape of the part, reduce, and avoid burrs to cut costs and lead times.
PiercingHere, the holes and slots fully enclosed within the edges of a part. Also, consider hole diameter and geometry for proper manufacturing and functionality.
BendingDesign the bends with enough material and space. Moreover, consider forming near holes to avoid deformation.
Notches and TabsIt includes the design with widths ~1.5x the thickness. It will avoid breakage during punching.
CornersHere, its corners radius is half of the material thickness. It will avoid sharp edges.
Burr ReductionAvoid sharp corners and complex cutouts. It will help in reducing burrs. Go with the burr direction during stamping.
CoiningFlatten or break the burrs during the stamping process to avoid costly secondary processes.
Plasticity & Grain DirectionChoose plasticity and grain direction for easier forming, especially for high-strength materials.
Bend HeightGive a sufficient bend height for effective forming, typically at least 2.5x the material thickness plus the radius of the bend.
Bend ReliefDesign with offsets or relief notches to prevent tearing along edges during bending.
Bend Distortion/BulgeChoose bending distortion or bulge by relieving parts before bending or consider the bend relief notches.
CountersinksAlways go with countersinking operations and potential bulges around holes to ensure proper fastening.
Carrying Web and Mismatch CutDesign for mismatch cuts during progressive die stamping to avoid part damage.

Tips for Effective Designing

So, once the tool design is done the second process is manufacturing. This manufacturing is carried out using different sheet metal stamping machines and other manufacturing services. So here are the details of the process involved in stamping.

2. Blanking

Once you complete the design part, blanking is the first in the sheet metal stamping process. Here is the rough outline of the metal part cut from the sheet.  We use a blanking die to cut the part in the required shape. So, when you are cutting the outline, make sure to reduce the burrs. Because they can have a bad impact on the final part. It can also need additional processing. Hence, the stamping die must be clear.  Besides this, always use sharp tooling to get clean edges.

Blanking Process

3. Punching

Punching includes making holes, slots, and other features in metal sheets. We use a punch, and a die set to carry out this process. So, the punch applies force on the metal sheet and inserts it into the die cavity. Then it comes out in the desired shape. So, the hole diameter, tolerance, spacing and geometry must be in control. It will give a proper fit and effective functionality of the final part. Additionally, if we deal with complex structures and shapes.  We may require specialized punches and sheet metal stamping dies.

Punching of Metal Sheet

4. Drawing

Drawing gives deep, cup-like shapes and hollow components. Here, we clamp the metal sheet from its edges. Then this sheet is pulled into a die cavity to get the required shape. Additionally, the drawing includes material deformation. In this case, apply adequate lubrication and choose the right material. It will help your metal to prevent wrinkling, wear-and-tear, and surface defects. Moreover, it will give you consistent forming as well.

Deep Drawing Process

5. Piercing

It works the same as a punching process.  But it also removes the material from the perimeter without disturbing the features of the desired shape. Moreover, this process is suitable for creating holes and slots near the edge of a metal part. It prevents bulging and distortion along the part edges. So, always use a clear die and sharp tools during this process. They will lead you to the clean edge and accurate hole dimensions.

6. Embossing

Embossing is used to make raised or sunken features on the surface of metal parts. So, it is considered as a decorative or a functional process. It is usually achieved by pressing the sheet between the male and female die set. This allows it to get the desired pattern on the surface of the metal. So, embossing needs careful control of pressure and die geometry. It will help achieve the desired depth and clarity of the features. Moreover, material stretch and thinning should be reduced. So, you can prevent tearing and distortion.

7. Coining

Coining is used to produce smooth and flat surfaces. We use it for the precision forming processes of the metal sheet. So, the sheet is compressed between two dies with the optimal pressure. It results in precise dimensional accuracy and surface finish. So, coining can significantly improve part quality. It also reduces surface roughness. Moreover, it improves dimensional accuracy. So, give high pressure and precise tooling and get consistent results.

8. Bending

Bending is a process that helps you create bends and folds in a metal sheet. So, it is achieved if you clamp the sheet between the punch and die. Then apply a force to deform the material. This process requires careful consideration of the material, thickness, bend radius and tool geometry. This will help you prevent wrinkling, cracking and excessive wear and tear. Moreover, apply lubrication and use proper tools. So, you can achieve uniform bending and dimensional accuracy.

9. Flanging

It is a bending of edges of the metal sheet at an angle to create flanges of lips. So, this process is commonly used in strengthened edges. It provides stiffness. Moreover, it facilitates the assemblies. So, flanging needs precise control of bent angles. It needs optimal material thickness and die clearance. So, it can get consistent flange dimensions and geometry. Make sure to apply proper support and clamping of the sheet. So, you can prevent distortion or wrinkling during flanging.

What Material You Use for Sheet Metal Stamping Parts

Here are some commonly used materials you can use for the stamping process.

MetalSuitability Details

Types of Sheet Metal Stamping

Based on different techniques, sheet metal stamping can be classified into the following types.

1. Progressive Stamping

It contains multiple features and has several stations. Each station has its duty. So,

progressive stamping is a highly automated metal working process. It is used to produce bulk of complex parts. This process includes feeding a metal strip through a series of stations. The station could be cutting, bending, shaping curling, etc. So, this strip starts to move through the press. Then move to the next station. Each station sequentially performs some tasks. So, when the final part comes, it is the combination of multiple operations.  So, it is efficient for high-volume productions. Moreover, it reduces the need for manual handling between operations.

2. Fourslide Stamping

This process is used to produce complex but small to medium-sized parts. These parts can have complex shapes. So, this process includes the use of a four-slide machine. This machine has four slides or tooling mechanisms to perform multiple operations. So, these four slide machines can bend, punch and form metal into different shapes. This combination of multitasking makes it a versatile process. It gives different components like clips, brackets and electrical contacts. Moreover, the main advantage of this process is that it produces parts with complex bends and angles. So, it can achieve tight tolerance and reduce the need for secondary operations.

3. Deep Drawing

Deep drawing helps you produce cylindrical or box-shaped components. These components can have greater depth than their diameter. So, during this process, you place a flat metal sheet or a blank in a die cavity and use a punch to draw the blank in the die. Then you apply force on it to take the shape of the cavity. You can perform this process in multiple stages. Each stage increment deepens the drawn part until you get the required shape. Deep drowning is used in parts production, like cans, containers, automotive body panels, kitchen sinks, etc, it serves metals with high strength and tight dimensional torrents. Moreover, this process is quite beneficial because of material savings, reduced weight and the ability to create smooth and complex geometries.

4. Transfer Die Stamping

It works like progressive stamping, as a metal strip is usually transferred from one station to another. But it uses mechanical or pneumatic transfer systems. Moreover, It can progressively produce more complex parts, and maintain high efficiency and precision sheet metal stamping is more suitable for parts with complex shapes and features, that we cannot achieve with a single stock.

5. Fine blanking

It is also known as fine-edge blanking. It is a precise metal stemming process which is used to produce high-quality parts, clean edges, and tight tolerance. Moreover, it uses special tools that apply three separate forces to the metal blank, i.e. cutting plank holding and counter pressure. So, this results in a smooth touch finish.  It reduces the need for secondary operations Like deburring or machining.

6. Shortened Stamping

If we talk about shortened stamping, it refers to the production of small batches. of stamp parts. Generally, it can produce a few hundred to thousands of pieces. Moreover, it is often used for prototyping product testing and fulfilling orders with low demand. Then frequent design changes. Sure. runs stamping may include. different techniques. but they are optimized for flexibility, quickness, and setup. They are quite cost-effective for smaller production volumes. So, the tooling and sheet metal stamping equipment must be designed to accommodate frequent changeovers. They must adapt themselves to the adjustments to meet varying production needs.

What are the Classifications of Metal Stamping Based on Processes

It is classified into two processes, i.e. forming and Material Separation. So, let’s discuss these in detail with their simplified drawings.

CategoryProcessProcess DescriptionSimplified Drawings
Material SeparationPunchingUse a mold to punch out the sheet along the closed line, resulting in workpieces and scraps.
BlankingUse a mold to punch out the plate along the closed line, resulting in workpieces and scrap.
ShearingCut off excess material from the edge of semi-finished products.
FormingBendingUse molds to bend materials into shapes.
CurlingRound the ends of the sheet.
TwistingTwist one part of the flat blank at an angle relative to another part. 
DrawingPress sheet material into a hollow workpiece while maintaining wall thickness.
StretchingChange the size of the hollow part to achieve required dimensions. 
FlangingTurn the holed edge of a sheet or workpiece into an upright edge.
HemmingFlange the outer edge of the workpiece.

What are the Tolerances for Stamped Sheet Metal

Tolerance helps in the precision of the stamping process? It is the allowable variance in dimensions and shapes. So, several factors influence the precision of stamping. It could be thickness, the complexity of dies and diameter, etc. So, let’s discuss the different tolerance values of stamped Metal Sheets.

DimensionTolerance RangeDetails
Linear Dimensions±0.05 mm to ±0.25 mm (±0.002 in to ±0.010 in)Depending on part size, complexity, and material.
Hole Diameter±0.05 mm to ±0.15 mm (±0.002 in to ±0.006 in)Diameter may vary based on hole size and depth.
Thickness±0.05 mm to ±0.10 mm (±0.002 in to ±0.004 in)Material thickness consistency is crucial.
Angle±1° to ±3°Can vary based on bending or forming operations.
Form Features (e.g., bends)±0.25 mm to ±0.50 mm (±0.010 in to ±0.020 in)Depends on the complexity and geometry of the form.
Hole-to-Hole Distance±0.25 mm to ±0.50 mm (±0.010 in to ±0.020 in)Critical for assemblies and fit with other parts.
Edge-to-Hole Distance±0.25 mm to ±0.50 mm (±0.010 in to ±0.020 in)Ensures proper clearance and alignment.
Edge-to-Edge Distance±0.25 mm to ±0.50 mm (±0.010 in to ±0.020 in)Critical for maintaining part geometry and fit.
