Coatings are an important aspect of metal composition. It has the properties of moisture-proof, weather-proof, pollution-proof, oxidation-proof and corrosion-proof. It is important to test the scratch resistance hardness of the material. A manufacturer responsible enough for testing scratch hardness can ensure they are providing their customers with the highest quality products and maintaining their brand reputation. By evaluating the coating quality, it is possible to ensure its thickness and spreading quality. Its adhesion can also be evaluated in the same way.
Pencil Hardness Tester – Motorized is a high tech material testing device used to test the scratch resistance of coatings when a load is applied. It complies with testing standards and delivers accurate results through automated features.
The machine is equipped with professional electronic controls to ensure long-term performance. The applied load is adjusted evenly over the specified diameter range. Install steel clamping pins to securely hold the sample. It operates using a cam system with swing arm movement. The machine offers an instant braking system so the test cycle can be stopped precisely at the desired point in time. Lights are fitted to the device to notify of any sample failure.
Place the test sample on the platform and position it correctly. Afterwards, it is clamped with metal pins to ensure zero slippage during the test cycle. The diamond nib area holds additional weights. According to the test requirements, the equipment provides different types of loads (1kg, 500g, 750g). Then, with a single button, users can start testing. After scratching the sample, the light will light up and indicate the same status.
After release, the test can be repeated under a different load or on a new sample to check the accuracy and consistency of the results.
