Producing graphite felt, rigid graphite board and CFC Using in Vacuum Furnace, polysilicon ingot furnace, Monocrystalline Silicon Furnace, inert atmosphere furnaces, crystal growth furnace, multicrystalline DSS, single crystal furnace, High Temperature Sintering Furnace, Directional Solidification System (DSS) furnaces, and much more Thermal Insulation Products for heat insulating.

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 1988. From our modern production factories 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). 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. 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 for special use according to clients' demands.
