Common types of stamping dies include single-step dies, multi-step dies, progressive dies, and compound dies.
Single-step Die
A single-step die is a common type of die designed to perform only one specific shaping operation per press stroke. Also known as a single-station die, it is used to form simple shapes and is typically employed for small-batch production or as a trial die during new product development.
Multi-step Die
A multi-step die-a type of complex die-performs multiple stamping operations within a single tool. Capable of forming various shapes through multiple sequential operations, it enhances both production efficiency and tool longevity. Multi-step dies are also referred to as multi-station dies.
Progressive Die
Also known as a positioning or feed die, the progressive die is a specialized form of multi-step die. It enables automatic feeding and continuous stamping; with each opening and closing of the die, the part is positioned, fed forward, and stamped. It is a standard choice for high-volume mass production.
Compound Die
The compound die-sometimes called a directional die-represents a modern manufacturing technique that integrates multiple stamping operations into a single tool, allowing various shaping tasks to be completed in one press stroke. Key characteristics include high production efficiency and the ability to handle complex stamping requirements; compound dies represent a major trend in the current die-making industry.
