To ensure we only provide customers with the highest quality products, we carry out thorough quality testing processes during production and after. Some of the tests include paint adhesion tests (cross-cut test), alcohol abrasion resistance tests, and hardness tests.
Paint adhesion test:
Evenly drawing 100 small grids on the mobile phone shell and wiping it quickly to test the degree of adhesion of the film to the substrate.
Alcohol abrasion resistance test:
Testing the degree of wear resistance of the pattern on the shell surface by alcohol.
We will test the harness of the mobile phone shell according to your demands.
