EDM GRAPHITE BLOCK

EDM graphite blocks are becoming more and more popular among our customers. EDM graphite is a new material. In recent years, with the development of China's industry, remarkable achievements have been made in science and technology. It has become the theme of The Times to create higher quality and lower cost in the field of precision mold industry. Therefore, graphite blocks for machining has become a new vane to look for newer graphite block material to replace copper electrodes in the industry. Therefore, the demand for EDM high purity graphite blocks from our company is increasing in many EDM graphite suppliers.
