The multi-function scratch tester consists of two parts of the scratcher, the left half can be used for a five-finger/plastic finger scratch test, and the right half can be used for a 100 grid scratch test. our company is Shanghai QINSUN Precision Electromechanical Technology Co., Ltd. independently develops and produces testing equipment with high cost performance and complete after-sales service. Both share a reciprocating mobile platform. This instrument meets various test standards and can adjust the movement stroke, movement speed and reciprocating movement cycle of the test platform according to customer requirements. It mainly detects the abrasion resistance of smooth and textured plastic coatings in automotive interior and exterior trim. In addition to material and product development, it also applies to quality control.
The Multifunctional Scratch Testerr consists of a motor drive mechanism, scratch mount, sample clamping and fixing devices, etc. The embedded system and man-machine interface are used to automatically control the testing process, and the precision servo motor and ball screw are used, which play a decisive role in the accuracy of the scraper speed control according to the relevant standards. The scraper assembly comprises a scraper bracket, a scraper finger, a positioning sleeve for the scraper finger, a pressure device and the like. The instrument can freely install, replace and disassemble scraper fingers of different specifications, and can perform uniform linear scraping movement in one direction under different loads. Tungsten carbide is used as a scraper finger to extend the life of the instrument. The instrument is made of aluminum alloy and stainless steel, which is simple, lightweight and corrosion resistant.

This test method is used to test the ability of the surface material to resist damage caused by finger scratching.According to the nails or other hard objects used come into contact with the material, scraping fingers of different materials are used to interact with a particular druk to act on the surface of the sample according to the specified direction, stroke and speed, and the scraping head and the sample make a relative movement, resulting in one-way, non-reciprocating linear scraping path, the scratches become parallel held. Evaluate the scratch sensitivity of the material, the color difference between scratched and unscratched areas, or the minimum scratch force when the sample surface is damaged.
