Using tungsten carbide as the scratching tip, this testing machine precisely detects surface wear caused by unconventional physical forms (scraping, grasping, planing, etc.). The test sample is fixed on the driven detection platform while five independent shaft rods with replaceable scratching tips apply constant vertical force to the sample surface.

The scratching head is installed on a hard stand, allowing operators to fix specified scratching heads at balanced positions through the bracket, enabling testing of samples with irregular widths. The instrument's excellent repeatability helps manufacturers effectively control production and inspect product performance.

This tester is designed for automotive interior materials including:

• Plastics and rubber materials
• Leather and coated fabrics
• Composite materials and paints
• Inks and soft metals

Widely used for quality control, new product development verification, testing by institutions, laboratory performance verification, and material property determination by quality technical supervision departments.
