Chin Ching Plant Ⅰ（Tunglo Plant）：Starting from selecting the right mine with a high purity of silica, then through the rigid production control, we are able to produce many specs of quality foundry and resin coated sand that have low clay content. Meanwhile we have imported the most advanced thermal reclaiming equipments for recycle sand to meet the requirements of environmental protection.
　
Chin Ching Plant Ⅱ（Touwu Plant）：We have provided our entire facility and latest technologies to Minexco (Vietnam), starting from surveying, mining, washing, classifying to shipping via vessel, each every process has gone through a stringent control system. The high purity Vietnamese Camranh Bay silica sand that we distribute, also goes through rigid iron stripping and grain sizing before supplying to glass foundry, and construction industries. Finally, by using the above silica sand as the main base material, grinded by the pebble millers, which are lined with silex, we are able to produce the high purity silica powder with low iron content.
