Metal stamping is a manufacturing process used to shape or cut metal into specific forms or patterns by using a die. It’s a high-precision technique often used in mass production to create parts for various industries, such as automotive, electronics, and appliances. The process involves feeding a metal sheet into a press, where it is then pressed by a die to form a specific shape.
There are a few main types of metal stamping operations:
1. Blanking – Cutting the metal into a desired shape or size.
2. Piercing – Creating holes or openings in the metal.
3. Bending – Shaping the metal by bending it at different angles.
4. Drawing – Forming a metal into a deeper shape, like a cup or a box.
5. Coining – Using pressure to reshape the metal without cutting it, often for fine detail or logos.
The process is used for parts like washers, brackets, electrical contacts, car body panels, and more. It's known for being efficient and cost-effective, especially when producing high-volume parts.
Stamping manufacturing (also called metal stamping or pressing) is a fabrication process used to convert flat metal sheets into specific shapes using a stamping press and dies. It is a high-speed and cost-effective method for producing large volumes of consistent parts.
Core Processes in Stamping Manufacturing
1. Blanking
Cutting flat metal sheets into smaller, predefined shapes (called blanks).
2. Punching
Removing material by forcing a punch through the sheet and into a die.
3. Bending
Deforming the metal at an angle along a straight axis.
4. Drawing
Stretching the metal into a 3D shape (e.g., making a cup from a disk).
5. Coining
Compressing the metal surface for fine detail or to thicken specific areas.
Types of Stamping
1.Progressive Die Stamping
The sheet metal moves through a series of stations; each station performs one operation.
High volume, very efficient.
2.Transfer Die Stamping
The part is transferred between dies using mechanical devices.
Suitable for large and complex parts.
3.Single-stage / Line Die Stamping
Each machine performs one operation; ideal for low-volume or large parts.
Advantages
High-speed production
Excellent repeatability and precision
Low labor cost per unit (after setup)
Great for high-volume runs
Challenges
High initial cost for tooling (dies)
Design changes are expensive once tooling is made
Tool maintenance and wear
Common Applications
Automotive parts (brackets, frames, body panels)
Electronics (connectors, terminals)
Appliances
Aerospace components
Medical devices
