The Scratch Tester is designed to evaluate the scratch resistance of materials such as automotive interior plastics, exterior coatings, and decorative panels. By applying a controlled load via interchangeable scratch heads, the device simulates real-world scratching and mechanical contact. It ensures objective assessment of surface durability, supporting quality control, R&D verification, and material selection for automotive manufacturers and suppliers.
You can use this tester to:
Assess scratch resistance of automotive interior plastic parts, including dashboards, door panels, and trim.
Evaluate exterior coatings, painted surfaces, and decorative panels for abrasion and scratch performance.
Conduct quality control and R&D verification for automotive paints and surface treatments.
Support material selection and comparative testing for OEMs (Honda, Nissan, Hyundai) and Tier 1 suppliers.
Test plastics, coatings, and decorative surfaces in laboratories, third-party testing centers, and manufacturing QA.

Prepare test specimens of the required size and clean surfaces.
Mount specimens securely using double-stick tape or clamp bar.
Install scratch head and confirm weight or perform calibration.
Adjust test arm to neutral balance to ensure only head weight is applied.
Set stroke length and scratch speed according to relevant standard.
Start the test using dual-hand activation switch.
Perform multiple scratch tests on different locations as required.
Upon completion, remove specimen and visually evaluate scratch depth, continuity, and visibility.
Record results according to standard requirements.
Inspect scratch heads regularly for wear or deformation; replace when necessary.
Keep test platform and arm clean to prevent residue affecting results.
Check screws, fasteners, and mechanical joints periodically to ensure stability.
Store the tester in a dry environment to preserve precision bearings and surface finish.
Verify test arm balance and calibration weights before each test session.
