Metal stamping

What Is Metal Stamping?

Defining Metal Stamping: Metal stamping is a versatile manufacturing process that uses mechanical presses and custom tools (molds/dies) to shape flat metal sheets into precise components through plastic deformation or material separation. By applying controlled force, we transform raw materials into complex parts with tight tolerances (±0.05mm typical) and consistent quality, ideal for high-volume production across industries.

Types of Metal Stamping Processes

Core Process Categories

Metal stamping processes are mainly divided into two categories: separation and forming. The following table details their characteristics, common operations, and typical applications:
Process Category
Process Characteristics
Common Operations
Typical Applications
Separation
Cut or separate material along defined contours.
Blanking/Punching, Shearing, Trimming
Automotive part blanks, electronic connector terminals
Forming
Deform material without separation to create 3D shapes.
Bending, Drawing, Flanging, Bulging
Appliance casings, aerospace structural components, medical device brackets

Advanced Stamping Techniques

  1. Progressive Die Stamping: This technique automates multi - step processes (such as punching, bending, and embossing) in a single press. With a high production rate of up to 500 parts per minute, it is highly efficient for high - volume production. For example, in the production of small metal components for electronics, progressive die stamping can complete multiple operations in one continuous process, reducing production time and cost.
  1. Fine Blanking: It produces burr - free, high - precision parts with a tolerance of ±0.02mm and smooth sheared edges. This makes it critical for manufacturing components in the aerospace and medical industries, where precision is of utmost importance. Components like aircraft engine parts and surgical instruments often require the high - precision manufacturing capabilities of fine blanking.
