Cupping test machine, TQC SP4400 digital display manual cupping machine

SP4400

cupping device

Compliant with ISO 1520 standard, manual model, built-in gearbox, Striker Diameter of φ 20mm, die base diameter of 27mm, safety emergency button, integrated audible alarm.

The cupping Tester is a special equipment used to test the cracking resistance and separation performance of the coating from the metal substrate at different deformation stages according to the ISO 1520 standard. The SP4400 cupping testing machine has a built-in gearbox to better reduce the manual force required to deform the test plate, and maintain pressure stably applied to the test plate to deform it evenly . The depth of indentation and deformation are displayed in digital form with a resolution of 0.01mm.

The SP4400 cupping Tester is a coating cracking resistance testing instrument approved by Qualicoat, QIB and GSB laboratories.

Application fields of cupping testing machine SP4400

Suitable for steel protection, galvanizing, laboratory, coating industry, paint and other fields testing.

Cupping Tester SP4400 operation method

1) Place the test plate in the clamping device of the SP4400 cupping Tester, with the coated side facing up; the thickness of the test plate should not exceed the thickness indicated on the specifications and Tester. Testing a test plate that is too thick may damage the drive shaft and cause deformation making the cupping Tester unusable;

2) Close the clamping device and keep the test plate clamped in place. Do not use too much force when clamping, otherwise when disassembling the test board, the operator will have to use a lot of force to loosen the test board;

3) Open the micrometer;

4) Gently turn the handle upward to raise the pressure head. To achieve an indentation speed of 0.2mm/s, one indentation is required every 2 seconds;

5) The test results are judged either based on the predetermined indentation depth or coating indentation evaluated on the test panel , or based on the depth of the first indentation on the coating;

6) After confirming the test results, return the indenter to the 0 position;

7) Loosen the sample clamping device and take out the sample.
