Metal Stamping design guidelines
There are many factors that will affect the cost and production process. Our engineers will support you to optimize your projects.
Different materials have varying properties that affect their suitability for stamping.During the production, the selection of materials is critical. We should take into account the grade, thickness, size, and other specifications. Only by choosing reasonable plates can it be possible to make high-quality stamping workpieces.
The thickness of the material is an important factor that affects the stamping effect. Material that is too thin is prone to deformation or breakage, while material that is too thick increases processing difficulty and cost. When choosing the material thickness, it is necessary to consider the design of the stamped part and the required mechanical properties to ensure that the finished product has sufficient strength and rigidity.
The accuracy of metal stamping is divided into precision level and economic level. Choosing the appropriate accuracy is helpful for cost control.
The appropriate tolerance range depends on the specific application and the functional requirements of the stamped parts. Therefore, it is crucial to carefully consider the required tolerances.
Metal stamping machines have minimum bend radius requirements to ensure the material does not crack or break during the bending process. Generally, a bend radius that is equal to or greater than the material thickness is recommended to prevent cracking or breaking.
The groove should be large enough to allow the material to flow easily during the stamping process. Additionally, the shape of the groove should be carefully considered to avoid sharp corners or angles that could cause stress concentrations and lead to cracking or failure of the part.
To prevent bulging and deformation in metal stamping, it is important to design holes and slots with proper spacing. Ideally, the distance between holes and slots should be at least twice the material thickness

What are the four type of metal stamping?
- Progressive Die Stamping : involves feeding a metal strip through a set of dies to create a finished part. The strip is moved through a series of stations where each station performs a specific operation on the metal until the final product is complete.
- Transfer die stamping: the part is transferred between multiple dies to complete the stamping process. It is often used for parts with more complex geometries or for larger parts that can't be produced in a single stamping operation.
- Fourslide Stamping:the machine uses four sliding tools to form the metal into the desired shape.
- Fine Blanking:a type of metal stamping that produces parts with extremely tight tolerances and smooth edges. This process involves a specialized tool that uses three main components to achieve the desired result: a punch, a die, and a blank holder.
What is the maximum thickness of material that can be used in metal stamping?
The maximum thickness of material that can be used in metal stamping depends on the specific capabilities of the stamping press, but is typically around 1/4 inch. If too thick, the cutting surface could not be smooth.
What types of tooling are used in metal stamping?
Metal stamping tooling can include dies, punches, blanking tools, and more.
What is the difference between short run and long run stamping?
Short run stamping is for smaller quantities of parts, typically up to 100,000 units, while long run stamping is for larger quantities, typically over 100,000 units.
What is the difference between progressive and transfer stamping?
The main difference between progressive and transfer stamping is the way the material is fed into the dies. In progressive stamping, the material is fed from a coil and moves through a series of dies to produce the final part. In transfer stamping, the material is fed from a blank and moves from one die to another until the final part is produced. Transfer stamping is often used for larger and more complex parts, while progressive stamping is more suitable for smaller and simpler parts.
