The cupping test machine is a testing device used to evaluate the resistance to cracking and delamination from the metal substrate when the coating film undergoes localized deformation due to indentation.
The cupping test machine is a testing device that evaluates the resistance to cracking and peeling from the metal substrate when the coating film undergoes localized deformation due to indentation. It is equivalent to the Erichsen tester specified in JIS-K5400. By attaching the included small CCD camera, the testing process is displayed on this liquid crystal touch panel display screen. Video recording and image capture can be performed via touch operation, and the data can be saved to a USB memory stick for transfer to a computer. The indentation speed and depth can be freely adjusted and saved. Automatic calibration can be performed using the included calibration zero plate. It is a fully automatic type, so the test begins with the push of a button. Indenter: 20mm diameter hemispherical; Indentation depth: 0-15mm; Indentation speed: 0.02-0.4mm/s; Maximum test panel width: 70mm; Test panel thickness: up to 1.25mm for steel plates and up to 3mm for aluminum.

basic information
Adjust the test specimen so that the center axis of the inserter is at least 35mm from the edge of the test plate, and secure it between the holding ring and the die. Testing at a constant insertion depth: Insert the tip of the inserter at a speed of 0.2±0.1mm/s to a constant depth, and inspect for cracks in the coating and peeling from the substrate. Method for measuring the minimum insertion depth that causes defects: Insert at a speed of 0.2±0.1mm/s until cracks in the coating and peeling from the substrate begin. Stop the insertion at this point and measure the depth of the inserter to the nearest 0.1mm.
