Overview1973 the Shanghu grinding wheel factory founded by Mr. Chaosheng Xu in Shanghu village becomes one of the few industrial enterprise in Yongkang County. At the beginning the factory employ only 10 workers to produce grinding wheel blades and it has a very small production scale. The products shipment can only be made through post office and the annual sales amount was about 100.000 RMB (14.000). In the following years the company increases sales in the domestic market and it starts to develop export trade. The employees carried the products to ship to the post office with bicycles or motorcycles. The enterprise gradually grew up and in few time it became the local biggest firm. Crown has 4 own factories located in China that fully conform international standards. All of them use TPS production management system. We directly produce over 90% of our products and when we make use of outsourcing suppliers they must fully conform to the highest standard both in terms of quality and labor protection.
