A Visit to Sanhui's Factory
As the saying goes, "To see is to believe", after we gained a general understanding of Sanhui, Mr. Zhou invited us to pay a visit to the factories as expected. There were three factories which cover around 25 acres in total, the main factory of Sanhui was 18 acres or so. Zhou showed us around the sample area where all its products range was displayed. Black silicon carbide powder of all particle sizes it produce is packed in small transparent bags from which we could have a clear view. There were a resistance particle counter and other technical machines for processing. According to Zhou, Sanhui has strict quality control over each process from raw materials to finished products. There were special technology testing equipment such as three microscopes， fluidized bed jet mill, resistance particle counter and three technicians in its physical laboratory. Usually finished products will be kept for one month in case that problems occur in customer feedback.
One of the successful deals of the company is that it has exported one hundred tons high bulk density section sand to Germany and received favorable effect. At present, due to sluggish market, Sanhui has downsized to maintain operation, Zhou seemed not dispirited at all. He said, "Although we have little control over depressed market situation, we can think of new ways to develop."
