All-in-one tester for dynamic scratch, punch and abrasion​

If you want to have further information or would like to submit a demo test, please contact us.

Basic Functions

Damage to a surface due to abrasion, scratch and punch is one of the main reasons for the disturbance of a product’s quality. In many real applications, deep scratch or severe abrasion occurs during a fast and high dynamic motion, e.g. a deep long scratch by a key on the exterior paint of a car, and this high dynamic scratch occurs at a high speed up to 150 cm/s.

Dyna -SPA®, is the only machine which combines all kinds of scratch, punch and abrasion tests within one machine with freely programmable speed and stroke. The speed is up to 150 cm/s and the stroke length is up to 120 mm. It complies with over 50 international standards (ASTM/DIN/ISO). Those common tests include cross-cut (crosshatch) test, crockmeter, key scratch and many more.

Measurement Principles

Reciprocating Mode

  • Pneumatic system drives the tip wheel to the prepositioning point “2” to ensure the right velocity for the test;

  • Then the tip is moving back and forth between point “2” and “3” at pre-defined speed, the inward and outward speeds can be different.

One-Direction Mode

  • Pneumatic system drives the tip wheel to the prepositioning point “2” to ensure the right velocity for the test;

  • Then the tip is moving from point “2” with a certain stroke to point “3” at    predefined speed;

  • A pushup rod will lift the pneumatic  cylinder to position “4” and reside back at the position “2” for the next cyclic linear motion.

Punch Test Mode

  • Pneumatic cylinder is flipped 180°;

  • Then the punch tip is hitting the sample back and forth between point “1” and “2” at predefined speed.
