Designed based on automotive industry standard technical requirements

The test sample is fixed on a compressed air driven detection platform. Five independent shaft scraping fingers, which can be replaced with different weights and selectable scraping fingers, are constantly applied vertically to the surface of the test sample. The scraper finger is installed on a hard platform, and the operator can fix the designated scraper finger in the balanced position through the bracket, so that samples with irregular widths can also be tested.

In addition to material and product development, it also applies to quality control
