Only the introduction of the facility, there is a limit to the quality and accuracy.
Years of experience, extensive know-how, flexible idea is realized fused,
we are skillful at ultra-thin film polishing processing technology and ultra-fine processing technology and welding technology.
From design and development stage on the basis of the drawings,
we will consult to customer request.
