About Erichsen Cupping Testing Machine

A Erichsen Cupping Testing Machine is a precision sheet metal testing instrument used to evaluate the ductility, formability, and deep drawing characteristics of metal sheets and strips. It determines the ability of a material to withstand deformation without cracking during pressing or forming operations.

This machine is widely used in sheet metal industries, automotive manufacturing, metallurgical laboratories, paint coating industries, and quality control departments for assessing material suitability for stamping and deep drawing processes.

Key Features

High-precision hydraulic or mechanical indentation system
Rigid and vibration-free heavy-duty frame construction
Smooth and controlled cup-forming operation
Digital / analog depth measurement system
Clamping system for secure sheet holding
Easy operation with quick test results
Accurate and repeatable performance
Conforms to ASTM / ISO / BIS standards

Working Principle

The machine works by forcing a hardened steel ball into a tightly clamped metal sheet at a controlled rate. The sheet is gradually deformed until a crack appears. The depth at which cracking occurs is measured and recorded as the Erichsen Index, indicating the materials formability and ductility.

Applications

Sheet metal formability testing
Automotive body panel material testing
Steel, aluminum, and alloy sheet evaluation
Paint and coating adhesion testing (indirect use)
Metal fabrication and stamping industries
Research and quality control laboratories
Educational engineering institutions

Advantages

Accurately determines sheet metal ductility
Essential for deep drawing process validation
Simple and reliable testing method
Helps prevent cracking during forming operations
Suitable for industrial and laboratory use

Technical Specifications (Typical)

Indenter: Hardened steel ball
Clamping system: Hydraulic / mechanical
Measuring range: Digital depth gauge / dial indicator
Sheet thickness: As per model capacity
