The Cupping Tester evaluates the formability of sheet metal and the flexibility or adhesion of coatings under deformation. A metal specimen, often coated, is clamped between a die and blank holder, while a spherical or hemispherical punch is pressed into the center to form an indentation. The test continues until either the substrate shows cracking or the coating exhibits failure. The punch depth at first failure, known as the cupping value or Erichsen Index, indicates the material’s or coating’s ability to withstand deformation. The test can be performed manually or automatically, with visual observation or integrated detection systems.
Application
(1) Quality control of incoming sheet metal to verify formability and ductility.
(2) Evaluating the flexibility, adhesion, and performance of paint, lacquer, coil coatings, and other finishes on metal substrates.
(3) Research and development of new metal alloys and coating formulations.
(4) Assessing the effects of material thickness, surface treatment, or aging on formability and coating performance.
(5) Ensuring materials meet requirements for deep drawing or forming processes.
(6) Comparing properties of different materials or coatings for manufacturing optimization.
Standards
(1) ISO 1520 – Metallic materials – Erichsen cupping test.
(2) ASTM E643 – Standard test method for indentation of metallic coatings.
(3) EN ISO 1520 – European standard for cupping test.
(4) DIN 50101 – German standard for cupping of metallic sheets.
(5) DIN 50102 – German standard for formability evaluation of coated metals.
Features
(1) Touch screen control technology for user-friendly operation.
(2) Customized operation system with direct input of test parameters via screen or mouse.
(3) Real-time display of cupping process, speed, and depth.
(4) Video and photo capture of testing process.
(5) Realtime monitoring of cupping image.
(6) Automatic calibration and zeroing.
(7) Manual and preset test modes.
(8) Provides quantitative cupping depth for precise material and coating evaluation.
