  DEAR Sirs,
  
  Gansu HaoShi Carbon Fiber Co., Ltd.(HSCF) is the leading manufacturer of PAN-based Carbon Fiber in China, HSCF began to research and industrialize in 1994. From Gansu HaoShi Carbon Fiber Co., Ltd.(HSCF) modern production plants in Central GANSU Province, CHINA, there have the China's largest high-temperature Vacuum Furnaces and entire process of production using computer-controlled temperature. The main products include premium high purity Carbon Fiber (HSCF) based of Carbon fiber board, rigid graphite board, graphite felt, graphite insulation cylinders, and carbon-carbon composites(CFC). 70% of manufactured products are exported in more than 30 countries of the world. Mainly used as insulation in high-vacuum and inert atmosphere furnaces. This kind of high-vacuum is widely used for metal heat treatment, meticulous and ceramic sintering, different kinds of crystallization production, producing optical fiber, and sintering monocrystalline silicon for semiconductors. Since these furnaces work at extremely high temperatures, it is necessary to have insulation material that can withstand such high temperatures. Moreover, for energy conserving purposes, quality heat insulation material is the best choice. We pride ourselves in the ability to offer first class technical backup to our customer base, and over the years we have developed close technical partnerships with major fields including Aerospace, Semiconductor, Solar Ingots, Specialist Castings, Metal Composites, Crystal Growing, Hard Metal Sintering, Graphitizing, and the Heat Treat Sectors.
  
  We can also research and develop new carbon materials (including composite materials) for special uses according to clients' demands.
  
  Ours products supplied to listed industries and for various applications.
