Coating Project for Earphone Accessories

In 2017, a large 3C foundry cooperated with Enijor on a coating project for earphone accessories. This type of product requires anti-fingerprint, good wear resistance, and acid and alkali resistance.

The difficulty of this type of product is acid and alkali resistance. Because the substrate itself is not acid and alkali resistant, there is a certain probability of film peeling in the acid and alkali sweat test after coating. A certain anti-oxidation film is formed on the surface, which overcomes this difficulty and meets the customer's delivery requirements.
