On May 11, 2022, the sapphire material finishing integrated operation center invested and constructed by HKWJ, the first material technology company in China to mass-produce 200-kg large-size sapphire ingots using bubble growth technology, was officially put into operation.
The new production base mainly produces sapphire finishing products such as mobile phone sapphire screen and sapphire substrate, which are widely used in LED, mobile phone electronics and other fields.
The project is by far the largest sapphire material finishing base in China.
