120mm Travel Distance Electric Pencil Hardness Tester For Digital Products
The Electric Pencil Hardness Tester is designed to evaluate coating hardness on various finished products, including mobile phone shells, MP3/MP4 shells, laptop computer shells, and other digital product enclosures. This electrically controlled machine utilizes an AC adjustable speed motor for smooth left-right movement with low noise and stable operation.
To test coating surface hardness, use a hardness pencil to scratch the coating surface. Secure the hardness pencil at a 45° angle, ensuring the pencil tip contacts the coating surface with appropriate load. Move the test platform to pass the coating surface across the pencil tip at a specified speed (JIS standard: 0.5 mm/s). The softest pencil hardness level that causes no damage (scratches) indicates the coating layer hardness.
