Cold Forging Progressive Stamping

"Progressive" refers to the sequence of dies arranged in a line (progressive die set), with each stage performing a specific forging and stamping step.

Applications

Cold forging progressive stamping is used to produce work-hardened complex components with excellent dimensional accuracy, material efficiency, near-net shape, and cost-effectiveness for automotive, aerospace, consumer products, healthcare devices, and general industrial applications.

How it works

Cold forging progressive stamping is a high-speed, high-volume metal forming process in which a metal blank is shaped through a series of incremental deformation stages, each performed in a separate die station without heating the material.

The process is carried out using a link motion or knuckle joint press, where the metal blank is plastically deformed within a precision-machined closed die by applying a unidirectional compression force along the z-axis. The part is formed from a metal strip blank and is transferred to subsequent stations either via an automated transfer arm system or by the integrated strip carriers. 

Industries we serve:

Features and benefits

Technical / quality features and benefits

01

High dimensional accuracy – tolerances in the +/-0.01 to +/-0.05mm range are common.

02

Superior surface finish – often eliminates the need for secondary machining or polishing.

03

High strength – work hardening increases yield and tensile strength without additional heat treatment.

04

Material efficiency – the process plastically deforms the material and strategically redistributes it to the desired locations within the die cavity, significantly minimizing raw material waste and enhancing utilization.

05

Multiple structural shapes are possible.

Economic / production features and benefits

01

Lower unit cost at scale – ideal for high-volume manufacturing.

02

Near-net shape efficiency – the forging process minimizes excess material by plastically deforming and shaping the workpiece close to its final geometry, significantly reducing downstream machining time, lowering production costs, and shortening lead times.

03

Dimensional consistency – achievable through the use of closed-die forging combined with fine stamping techniques, which ensure precise material flow and tight control over part geometry, resulting in consistently accurate dimensions across production batches.
