Scratch Resistance Test machine

The Scratch Resistance Test Machine is a precision testing instrument designed to evaluate the scratch performance of rigid organic materials, coatings, adhesives, powder coatings, anodized materials, soft metals, plastics, and glass. It can also assess adhesive quality of protective coatings and the extreme performance of similar materials. The machine uses a balanced beam, fixed and adjustable weights, and a sample loading disc to produce controlled arcuate scratches on the test surface, providing accurate, repeatable, and quantifiable data for material development and quality control.

Application

The Scratch Resistance Test Machine is suitable for a wide range of materials and testing scenarios:

Evaluation of rigid organic materials, plastics, glass, and metals for scratch resistance

Testing coatings, adhesives, and powder coatings for durability and adhesion quality

Assessment of furniture surfaces, countertops, and high-pressure laminates

Comparative studies of protective coatings or similar materials under controlled loading

Test Procedures

Sample Preparation:

Select a representative sample of the material to be tested.

Measure the thickness of the sample to adjust the balanced beam height accordingly.

Setup:

Install the scratch tip in the middle of the balanced beam.

Mount the sample on the loading disc, ensuring the beam remains level.

Fix the standard weight and position adjustable weight to set the desired load.

Testing Procedure:

Rotate the sample disc counterclockwise; the scratch tip will create an arcuate scratch on the surface.

Record load, scratch spacing, and sample speed using the industrial computer.

Repeat as necessary for multiple samples or comparative studies.

Maintenance Information

Regularly inspect and clean the scratch tip to prevent contamination.

Verify balanced beam alignment and load accuracy before each test.

Check stepper motor and gearbox operation for smooth rotation.

Calibrate the system periodically using standard weights and test samples.
