Electric pencil hardness tester
Model
DDY type
Product Introduction
The electric pencil hardness tester is suitable for testing the spray hardness of various home appliance and digital product casings such as mobile phone casings, MP3/MP4 casings, laptop casings, and for testing the hardness of various metal coatings, decorative materials, synthetic leather, and other paint fields. This machine uses a pencil with a certain hardness rating to scratch the coating of the product, and uses the hardest pencil rating that does not cause damage to the coating to indicate the hardness of the paint. This complies with the requirements of GB/T6739-2006, ASTMD3363, ISO15184, BS3900-E19, ECCA-T4/1, JIS, CNS and other standards.

Product testing
This machine tests the surface hardness of the coating layer by scraping and scratching the surface of the coating layer. The hardness pencil is fixed at a 45 ° angle, with the tip of the pen in contact with the surface of the coating layer, and an appropriate load is applied. The test platform is moved at a certain speed (JIS standard 0.5mm/second) to move the surface of the coating layer past the pen center. The softest pencil grade that will not cause damage (scratches) to the coating layer can be considered as the hardness of the coating layer.
Matters needing attention:
1. Before machine testing, the entire machine must be placed horizontally;
2. Before testing, the speed should be adjusted to the lowest level to allow the machine to operate normally before adjusting the speed to the required testing value;
3. The template must be clamped tightly to prevent loosening from affecting the test results.
Maintenance matters
To maintain the appearance cleanliness and mechanical lifespan of the machine, please follow the following suggestions for regular maintenance and cleaning:
1. The panel can be cleaned with degreasing oil.
2. The paint part can be cleaned with degreasing oil and pine perfume.
3. Please wipe the fixture part clean regularly to ensure effective and powerful clamping of the product.
4. The lubricating grease (industrial butter) between the internal transmission structure connecting rod and connecting rod screws, as well as between the two sliding rods and linear bearings, needs to be replaced every half month of normal use. The original lubricating grease needs to be cleaned in advance.
