Graphite heaters are widely used in various industrial furnace heating systems. They are characterized by high temperature resistance, uniform heating, resistance to chemical corrosion and long service life. It is the best choice for high temperature heating above 2300 ℃. We can produce different shapes of graphite heater according to the demands of the user.
Graphite heating element is widely used in kinds of heating system of industrial furnace. Ithas advantages of high temperature resistant, temperature uniformity, chemical resistance, long working life and so on. It is the best choice to high-temperature heating (above 2300*0). And we can produce heating elements with different shapes according to users* demands.
Graphite mold is widely used in all kinds of precision casting. It has the characteristics of high temperature resistance, high machining precision, uniform heat conduction and easy demoulding. With the development of science and technology, graphite mold will be used more widely in many fields.
Graphite mold is widely used in kinds of precision casting. It has advantages of high tempera-ture resistant, high machining accuracy, temperature welldistributed, easy demould and so on. With the development of science and technology, graphite mold will be bound to apply in more fields
Furnace rectangular is mainly used in electrode graphitization furnace, carborundum smelting furnace and so on. The graphiterectangularelectrode produced by our factory has the advantages of low resistivity, good thermal conductivity, high density and good oxidation resistance.
Graphite rectangular electrode is mainly used in electrode graphitization furnace, carborundum melting stove, our products have the characters as low resistivity, high density, good performance of electric and thermal conduction，and good anti-oxidant.

Graphite heaters are widely used in various industrial furnace heating systems. They are characterized by high temperature resistance, uniform heating, resistance to chemical corrosion and long service life. It is the best choice for high temperature heating above 2300 ℃. We can produce different shapes of graphite heater according to the demands of the user.
Graphite heating element is widely used in kinds of heating system of industrial furnace. Ithas advantages of high temperature resistant, temperature uniformity, chemical resistance, long working life and so on. It is the best choice to high-temperature heating (above 2300*0). And we can produce heating elements with different shapes according to users* demands.
Graphite mold is widely used in all kinds of precision casting. It has the characteristics of high temperature resistance, high machining precision, uniform heat conduction and easy demoulding. With the development of science and technology, graphite mold will be used more widely in many fields.
Graphite mold is widely used in kinds of precision casting. It has advantages of high tempera-ture resistant, high machining accuracy, temperature welldistributed, easy demould and so on. With the development of science and technology, graphite mold will be bound to apply in more fields
