BGD 309 Cupping Tester is applicable to evaluate crack resistance and detachment of coatings from metal substrates after the coating layer has been deformed gradually under standard conditions.
A 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.

Technical Specification
In compliance with ISO 1520 BS 3900 Part 4 DIN 53166 DIN 53233 etc
Automatic coordinate positioning system: tester can memorize the home position after being zeroed, also track the punch's position automatically. Therefore, the traditional error caused by return or shake can be avoided.
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 2,500N.
The coordinate position of the plug can be zeroed manually and can be memorized.
10X illuminated magnifier, convenient to observe and evaluate the test result.
Hand twist operation: laborsaving and easy-handling.
