With the evolution of advanced science and technology. Optical parts need more mass production. It is this combination of our advantages: high precision tooling and manufacturing technology to achieve this possibility.
Task The window needs highly optical function and precise position. Sleeve also need very smooth and precision for the optical function need.
Solution The products need contact with the person's mouth. From our highly mold technology and workmanship to build the double injection mold and sleeve mold. Achieve the high precision and smooth need. The window made by PMMA material. It's also by high polish and optical coating for reach the optical needed.
