In February 2015, a Russian customer visited Wuxi Caston Drill Tools Co., Ltd.. He learned about the overall production capacity and quality guarantee, as well as the product technology and research achievement, and highly praised the company’s capability. The customer learned about the details of each process of the production and the process control and tested the product by himself. He also learned about Caston’s market share and comments from domestic customers, and made a comparison between Caston products and drill tools products of other brands. Then he showed great confidence in Caston’s product quality, price and services and placed an order, which laid the foundation for the export of large drill pipes.
