Cupping Test Apparatus

Cupping Test Apparatus

Cupping Testing Apparatus is scientific equipment to know the quality of paint on the pre-painted sheet, therefore, in a cupping testing machine the samples are cut and deep-drawn according to the Erichsen Principle to determine the depth to which they can be drawn before the paint cracks.

Hand-operated, rugged ERICHSO TESTER is designed to find the deep drawability (ductility) of metallic sheets and strips as per Erichsen Principle for cupping test.

The cupping test apparatus is designed to test the elongation and deformability of lacquers and protective coatings applied to metal substrate. The test apparatus is based upon the Erichsen Principle which is used to perform a cupping test on a coated steel panel having a thickness of 0.8 – 2 mm to define the resistance of paints, varnishes and related products to cracking. This test is determined on a coated steel panel by testing to a specified depth at which coating fails.
