Brief Introduction:

Scratch tester used for a variety of automotive interior materials, such as plastics, rubber, leather, fabric, coating materials, coating materials and other non-composite materials such as scratch resistance detection.

Core advantages:
Scratch testers from Qinsunlab can be used to characterize film-substrate systems and to quantify parameters such as adhesive strength and friction force and using a variety of complementary methods. This makes them invaluable tools for determining coating adhesion, scratch resistance and mar resistance in research, development and quality control.
Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method).
This adjustment allows the scale beam to be maintained in a level position in respect to the specimen and turntable.  Designed with an integrated bearing, the scale beam can be tilted in a rest position enabling the operator to mount or remove specimens.
Applicable Standards:
GB/T 2918,GB/T 6151,GB/T 8424.3,PV3952,BMW GS97034-2,BMW GS97034-9,GMN 3943-2003,FLTM BN 108-13,STD1024-3113,GMW 14698-A,GMW 14688

Instrument features:

1. The apparatus consists of the drive motor mechanism, scraping component, the sample holder fixing devices and other components.
2. The scraper assembly includes a bracket scratch; scraping means scrape the specified bit sets, pressurizing means (weights and weight support bar) and the like.
3. Free installation, replacement and removal of different specifications, scraping means can be implemented in a uniform way linear motion scraping under different loads.
4. The use of embedded systems, man-machine interface for automated control of the testing process, using precision servo motor, ball screw driver for the scraping speed standards under the control accuracy with a decisive role.
5. The use of tungsten carbide makes scraping means, increase the instrument pot life.
6. The use of aluminum and stainless steel, simple appearance, lightweight and corrosion resistant.
