Erichson Cupping Testing Machine

Description

The Erichsen Cupping Test Machine is a standardized material testing instrument used to evaluate the ductility and formability of sheet metals under biaxial stress conditions. This test determines a material’s ability to withstand stretching and deformation—critical in processes such as deep drawing, stamping, and forming. The machine performs the test according to ISO 20482 / DIN EN 10132-2 / IS 10175, generating a cupping value (in mm) that indicates the material's drawability. This test is essential for automotive, aerospace, appliance, and metal packaging industries, where sheet metal formability directly impacts product quality and manufacturing efficiency.

Key Features

• Complies with ISO 20482, DIN 50101, and IS 10175 standards • Measures sheet metal formability via cupping depth before rupture • Manual, motorized, or fully automatic operation models available • Rigid frame with precision-aligned punch and blank holder • Fine-adjustable loading speed for accurate control • Digital or analog depth measurement indicator • Optional data logging system and graphical output for lab analysis • Safety enclosures and overload protection for operator safety
