Digital Cupping Tester

        Cupping Tester is applicable to evaluate crack resistance and detachment from the metal substrate of coated surface which is coated with paint, varnish, etc., after the coating layer is deformed gradually under standard condition. The sample panel(max. 1.25mm thick×70 mm width, coated min.0.03mm)is clamped by an upper wheel and manually cupped by a 20mm  hemispherical indenter onto a 27mm die by a drive wheel. The depth to cause failure is indicated on a precise digital display. The results can be easily observed with an illuminated magnifier.

Feature:

 Compliance withISO 1520,BS 3900 Part 4,DIN 1502 etc

 Automatic coordinate positioning system: machine can memorize the home position after being zeroed, and locate the plugs position automatically. Therefore, the traditional error caused by replacement or wobble can be eliminated.

  Highly precise position sensor: the minimum division value of the depression depth can reach 0.01mm.

  Applicable for every kind of substrate, and the maximum pressure can reach 2500N.  

 The coordinate position of the plug can be zeroed manually and can be memorized while it is cold.

  Hand twist operation: laborsaving and easy-handling.
