This furnace applies blackening treatment (forming Fe3O4) to shadow masks, frames, and inner shields by means of temperature, atmosphere (D gas), and dew point control.

Recently, the blackening treatment of Invar (36% Ni alloy) for CDTs and large TVs has been dominant. We are the world's leading company in this area.
