The Surface Scratch Resistance Testing Machine is designed to evaluate the scratch resistance and mechanical durability of coated surfaces under controlled load conditions. It is primarily used to assess the resistance of printed circuit board coatings and enclosure surfaces to scratching, ensuring compliance with electrical safety and mechanical strength requirements defined in relevant standards. The equipment provides stable, repeatable scratch testing results for quality control, product development, and conformity assessment.
Application
Scratch resistance evaluation of printed circuit board (PCB) coatings
Durability testing of surface coatings on electrical and electronic enclosures
Mechanical strength verification of plastic or coated housings
Quality control testing for household and similar electrical appliances
Compliance testing for safety-related surface durability requirements
Typical test samples include:
PCB protective coatings
Plastic housings and covers
Electrical appliance enclosures
Coated metal or composite surfaces
