WHAT IS METAL STAMPING?

What Are Stamped Parts?

Stamped parts are products formed by placing metal material into a die mounted on a press machine and applying high pressure. By combining operations such as cutting, bending, stretching and drawing, parts of many different shapes can be produced.

Stamping can produce large volumes of identical parts with consistently high precision. As a result, stamped parts are used as internal components in many products, including semiconductors, automobiles and electronic devices. Part quality depends largely on the precision of the die and the processing expertise.

Technology

Main Stamping Methods

M-01

Progressive

Progressive Stamping

In this method, strip material is fed forward at fixed intervals while multiple operations are performed in sequence within a single die. Because several operations are carried out with each press stroke, small, complex parts can be mass-produced efficiently. It is well suited to lead frames, connector components and similar parts.

M-02

Transfer

Transfer Stamping

In this method, workpieces are moved one at a time to the next stage as they are formed. It is suited to parts with deep or three-dimensional shapes. Kataken Seiko has also developed and supplies its own high-speed transfer system.

M-03

Single-Stage

Single-Stage Stamping

This is the basic form of stamping, in which one die performs one operation. It is suited to prototyping, low-volume production and the processing of large parts. Depending on production volume and part shape, it is used in combination with other methods.

M-04

Deep Drawing

Deep Drawing

This method forms flat material into three-dimensional, container-like shapes. It is used for products with depth, such as tubular parts and covers. Designing the die to suit the material's properties is essential.

M-05

Micro / Precision

Micro and Precision Stamping

This technology processes very small parts and thin materials with high precision. It handles the fine, highly accurate shapes required in the semiconductor and electronic component fields. Our expertise as a die manufacturer translates directly into part quality.

M-06

Integrated

Integrated Die Making and Stamping

Kataken Seiko carries out both die design and manufacturing and stamping within the same company. Because ease of processing can be considered from the die design stage, quality is stable and the transition to mass production is smooth.
