What is Stamping Process?

What-is-Stamping-Process
Stamping processing is a manufacturing process that utilizes molds to apply pressure on metal sheets, causing plastic deformation or separation to rapidly form desired shapes. 
Characterized by high efficiency, precision, and suitability for mass production, it is widely employed in manufacturing complex components for automotive, electronics, and other industrial sectors.

Stamping Material

Copper
Brass
Steel
Stainless Steel
Aluminum

Copper

Copper is widely valued in the electrical industry for its excellent electrical and thermal conductivity. These high-purity coppers are ideal for use in switchgear, transformers, motors, and power distribution components. Its excellent corrosion resistance, strength, and formability make it a trusted material in demanding electrical systems and energy infrastructure.

Advantages of Stamping

Design Flexibility

Customized punches and dies that can stamping bevels, chamfers, locking edges, micro‑holes, and other complex contours

Automation

On-line access to product parameters, rapid change of molds, shorten the switching time, improve production flexibility.

High Consistency

CNC positioning guarantees constant stamping parameters for each press, stable and consistent product size and shape, significant increase in yield rate.

High Material Utilization

Narrow and neat cuts, small waste area, sheet utilization rate of more than 95%, effectively reducing raw material procurement costs.

Assembly Services

Assembly-Services-
Stamped parts are usually assembled in an assembly. We offer the following assembly services, which can help your product to be put into use faster: 
● Assembly of Elastic Parts 
● Riveting 
● Welding 
● Surface Treatment 
It should be noted that the assembly service needs to extend the production time by about 2-3 days.
