Stamping

Frequent asked questions about Sheet Metal Stamping

 

 

 

 

What are the differences between making it cold and hot?

When hot, greater deformations can be obtained, but it has several drawbacks. On the one hand the precision is not as good as cold. And on the other hand, the fact of working with very high temperatures (higher than 900 degrees), makes the process of forming the pieces more expensive.

How is it done cold?

This is usually done with presses and dies. Thin-thick metal sheets or sheets are worked. Pieces are made of sheet metal or stainless steel or other materials.

 

 

What is it used for?

It is used to create pieces with little relief.

Depending on the type of sheet material, they can be pieces that can be used indoors or outdoors. Depending on the application and the sector, the appropriate sheet and thickness are selected.

They are usually processes for making pieces in medium or large series.

What are the most common processes in the manufacture of sheet metal parts?

The most common are drawing, stamping, punching, perforating, cutting, bending, rolling to perform sheet metal forming.

As finishes, 3D laser cutting and polishing can be performed depending on the raw material used.

From what depth could we say what is deep drawing or sheet metal stamping?

The boundary between deep drawing and stamping is not defined. It could be said that when the result is a container, or when they are hollow pieces, it is called deep drawing.

Metal Stamping

Metal stamping is a manufacturing process that involves the use of presses and dies to transform sheets of metal into specific parts. This process can include various operations such as cutting, bending, punching and forming, and is used to produce flat or simply shaped parts. Stamping is ideal for mass production of uniform parts with high precision.

Printing Features:

  • Cutting and Bending: The main operations are metal cutting and bending.
  • Precision: High precision in the manufacturing of parts with tight tolerances.
  • Mass production: Efficient for large production volumes.
  • Versatility: Can work with different types of metals and thicknesses.

Metal Embossing

Drawing, also known as deep drawing, is a forming process used to transform a flat sheet of metal into a three-dimensional shape by applying compressive forces. During this process, the metal is stretched and formed around a mold, creating hollow pieces with greater depth than those obtained with stamping. It is commonly used to manufacture components such as casings, containers and other complex shaped parts.

Characteristics of the Embossing:

  • Deep Forming: Allows you to create deep and complex three-dimensional shapes.
  • Material Stretch: Metal stretches to conform to the shape of the mold, which can pose a higher risk of fractures or warping if not properly controlled.
  • Specific Applications: Ideal for parts such as containers, housings, and hollow structural components.
  • Requires Ductile Materials: Normally used with materials that have good ductility to avoid breakage.

Main differences

  1. Kind of product:

    • Stamping: Mainly produces flat pieces or pieces with simple shapes.
    • Deep drawing: Produces deep, three-dimensional pieces.

  2. Forming Process:

    • Stamping: Involves cutting and bending operations.
    • Deep drawing: Involves stretching metal to form a hollow piece.

  3. Applications:

    • Stamping: Used for parts such as electronic components, flat automotive parts, etc.
    • Deep drawing: Used to manufacture casings, containers, and parts with complex shapes.

  4. Material:

    • Stamping: Can be used with a wider variety of metals.
    • Deep drawing: Requires metals with high ductility to avoid fractures during stretching.
