    Digital Cup Bulge Testing Machine

    Overview Knowledge Standards Terms
    The digital cup bulge tester presses the specimen into a cup-shaped mold through hydraulic pressure to measure the cracking resistance and ductility of coatings or films. It digitally displays real-time depth values and is used for quality control and process validation of materials such as coatings, inks, and plastics.
    Selection
    When selecting, consider the material type and thickness to match the indenter size, ensure the measurement range meets the requirements of testing standards, and the accuracy satisfies a resolution of 0.01mm. The operation interface should be simple, the body structure sturdy, and standard fixtures should be included. Calibration certificates and after-sales support should be complete.

    Cup Test Instrument for Coating Tests the Impact and Deformation Resistance of Coatings on Metal Substrates.
    This article introduces how the coating cupping tester measures the resistance to stamping deformation of coatings on metal substrates.
    Cupping test instrument detects the cracking resistance of coatings under deformation.
    This article introduces how the cupping test instrument detects the cracking resistance of coatings under deformation. It uses a spherical punch to uniformly press against the back of the sample, causing the coating to bulge with the substrate, simulating biaxial stretching until the coating cracks. The indentation depth at this point is recorded as the key indicator.
    Cupping tester evaluates the ductility of coatings.
    The cupping tester is a detection device used to evaluate the ductility of coatings under biaxial tension. During the test, the punch presses the sample into the die until the first continuous crack appears in the coating, at which point the penetration depth of the punch is recorded as the cupping depth.
