GBW-60 Automatic Cupping Tester

Product Introduction
The GBW-60 automatic cupping tester is a microcomputer-controlled testing machine designed to evaluate the ductility and plastic deformation behavior of metal sheets and strips. It measures the cupping depth of a specimen under controlled punching and clamping forces, helping assess sheet metal formability and directional differences in deformation behavior.
Compliant with the Chinese standard GB/T 4156-2007, Metallic Materials—Sheet and Strip—Cupping Test, the GBW-60 is equipped with high-precision sensors for testing thin metal sheets with thicknesses ranging from 0.05 to 2 mm. It is suitable for quality control, material evaluation, and metal forming research.

Performance Features
• Automatic testing: Microcomputer-controlled operation supports consistent and repeatable cupping tests.
• High-precision measurement: Cupping depth resolution of 0.01 mm enables detailed evaluation of metal sheet ductility.
• Wide specimen thickness range: Tests metal sheets from 0.05 to 2 mm, including ultra-thin materials.
• High testing capacity: Maximum punching force of 60 kN and maximum clamping force of 10 kN.
• Adjustable test speed: Testing speed ranges from 0.01 to 200 mm/min.
• Standardized tooling: Supplied with standard punching and die dimensions for GB/T 4156-2007 testing.
• Custom tooling options: Non-standard dies can be supplied on request, with configurations available for applicable international standards.

Working Principle
The GBW-60 automatic cupping tester clamps a metal sheet specimen between the die and clamping components. A spherical punch then moves against the specimen at a controlled speed, progressively deforming the sheet into a cup-shaped indentation.
The instrument measures the cupping depth at the specified test endpoint, providing an indication of the material's ability to withstand plastic deformation without cracking. The results support comparisons of sheet metal formability, ductility, and deformation behavior under standardized test conditions.
