EDM graphite: EDM is a revolution in today's mold industry, which means not only simplifies the traditional process, but also the manufacture of shaped mold as possible. Isostatic graphite due to the sale of isotropic graphite, is the best material for the manufacture EDM graphite electrodes. Graphite products have chemical stability and resistance to erosion. Graphite has good chemical stability at room temperature, high carbon graphite manufacturers, without any strong acids, alkalis and organic solvents erosion. Therefore, even if the long-term loss of graphite products rarely, just wipe clean also as good as new. Graphite products with a strong oxidation and reduction of the role. Products in particular, can have a negative oxygen ions graphite mattress after heating, the surrounding objects activated graphite, maintain health, prevent aging Lacey graphite, skin shiny and elastic. Technical characteristics of graphite is mainly determined by its crystalline form. Graphite crystal form different minerals, having different values ??and industrial uses. Industrially, depending on the crystalline form, natural graphite into three categories. Lacey graphite, carbon industry in the North Sea Dragon (certified), graphite is provided by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) Shandong Weifang, graphite and carbon products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the North Sea Dragon carbon industry leadership with the staff warmly welcome all inquiries negotiations to create the North Sea Dragon carbon industry a better future.
