THE APPLICATION OF GRAPHITE

Vacuum furnace 

Graphite material is ideally suited for high temperature applications in vacuum atmosphere. Thanks to its physical, chemical and thermal properties. The application temperature can stand up to 2300 degree C. Also, graphite have the advantage of heating structure uniform, good performance of electrical conductivity, high current capacity, high corrosion & oxidation resistant, high degree of chemical purity and high mechanical strength.

 

Vacuum furnace now can used in Arc melting, Brazing, Ceramic Firing, Crystal growing, Heat Treating, MIM, CVD, CVI, Hot Pressing Laboratory research, Powder metallurgy, Purification, Debinding, Sintering and Wire annealing.

Metallurgical Indust

 

According to the properties of small thermal expansion coefficient, stable chemical specification, high temperature endurance and high intensity of thermal conductivity , the graphite material is process into mold and sintering boat, to produce the hard alloy and other metallurgical processes.

 

Dasen Graphite provides a wide range of graphite products to the metallurgical industry including: 

1. Continuous Casting Dies

2. Crucibles

3. Electrode Machining

4. Furnace Components

5. Molds & Dies

6. Sintering Mould/Boats 

 

 

Photovoltaic industry

The development of photovoltaic industry and the application of graphite is inseparable. The heating system for single crystal furnace used a large number of high purity graphite material. In the 21st Century, the photovoltaic industry has been rapidly developed. Solar battery poly silicon ingot material has made a great progress in production and the market requirements which also gave the graphite products new markets in the field of photovoltaic industry 

 

 

Graphite products which used in the single crystal furnace are all wearing part. It is composed by a variety of high purity graphite. All components and systems made from ISO graphite, high purity molded graphite may optionally be ordered to suit your own requirements. 

 

Continuous metal casting

 

Molten metal can cast through a graphite mold. Graphite mold is reusable whilst some designs only need a mold of one-time use. Casting directly into graphite molds to produce precise and create small grain casting.

 

 

We supply graphite ingot moulds for: 

 

1. Non-ferrous metals (Bronze, brass, aluminum and copper)

2. Noble metals (Gold, sliver and jewelry)

We can manufacture your parts according to your drawings or rough sketch.

 

 

Bipolar Plates for Fuel Cell

Using renewable energy , fuel cell transforms the chemical energy into electricity with zero emission  and portable which is the solution for the future alternative energy.

 

 

Dasen began to engage in the fuel cell industry for many years and successfully developed the super thin graphite Bipolar plates which reduce the volume and weight of the fuel cell stacks dramatically with its excellent performance, stable application and competitive price. In the past several years, Dasen had produced millions graphite Bipolar plates.

 

Dasen provide suitable graphite bipolar plates for different fuel. 

Hydrogen special graphite bi-polar plates

Methanol special graphite bi-polar plates
