The Chair Man Hi-tech CO., LTD, founded in 1984, has been consistently dedicating to study and manufacture fine ceramics. We have been investing in the R&D and fabrication of SiC products ever since 2000, and successfully mass-producing the S-SiC products since 2004. To promote product&＃39;s quality, we keep on purchasing new equipment and elevate the production technological level. Moreover, we also have built a standard quality check system to maximize our quality level in the standardized production line. In 2005, we (Chair Man) have passed the ISO-9001 certification procedure; all of our customers therefore can rely on our product&＃39;s quality most. Except asking for product&＃39;s high quality, we also pay particular attention on our service attitude. We always hold the goal of "Customer First", helping our customers solve problems of various kinds they encounter.
