2. Specialties graphite (graphite mold, graphite crucible, graphite block, graphite rod…)
Specialty carbon graphite materials include medium grain graphite, fine grain graphite, and ultra-fine grain graphite.
Specialty carbon products (Carbon specialties) will realize the carbon's extensive potential. They are high-performance products that underline the development of key industries such as electronics, machinery, and metallurgy. They are also used in cutting-edge fields of science such as semiconductors aviation and the aerospace industry.

Features of specialties graphite:
• High temperature resistance, and the melting point is 3850±50°C, the boiling point is 4250.
• Low ash content, high purity, avoiding pollution to your products.
• Graphite material is easily to machine into any shapes you like.
• High mechanical strength
• Good sliding properties
• High thermal conductivity
• High thermal shock and chemical resistance
• Food safety
• Low wettability
• High corrosion resistance and oxidation resistance
• Good electrical conductivity
• High density and high mechanical strength
• Proper electrical conductivity
Main properties of specialties graphite:
Notes of operating graphite crucibles:
1. The crucible should be stocked in the dry situation
2. Carry the crucible lightly
3. Warm the crucible in the drying machine or near the furnace. The warming temperature should be up to 500ºC.
4. The crucible should be put under the furnace month flat.
5. When put the metal into the crucible, you should take the crucible capacity as your reference. If the crucible is too full, it will be damaged by expansion.
6. The clamps shape need as that of crucible. Avoid the concentrate stressed destroy of the crucible
7. Clean the crucible regularly and lightly.
8. The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace.
9. Turn the crucible once in one week and this will help lengthen the service life.
10. The flame should not touch the crucible directly.
11.24 hours constant use will make crucibles have longer service life.
The smelt soup in the crucible should be cleared out when the furnace stop working, in order to avoid molten soup solidificating and will be expanded when fire to reheat, and affect the service life of crucible or even burst.
12. We suggest that about 2 months for crucible melting aluminum alloy
(every week for melting copper alloy), hanging out to check whether there is something wrong in the surface, and clean furnace hearth as well as turn the crucible, this operation ishelpful to prolong the service life of crucible.

5. Quality control (STRICT QC SYSTEM):
Quality policy - The policy aims at satisfying our customer by way of initializing an updated quality management and sticking to the top requirement of "quality first" in an attempt to achieve an elite project finally.
Quality objective - Provide our customer with products in full line with relevant contract and standard by way of strictly conforming to quality control procedure and intensifying avoiding common quality faults to be sure of an effective operation of the quality assurance and quality control system, achieve a zero quality accident rate and realize good project construction quality.
Quality Assurance System and Function - Establish quality assurance and effective quality control system before construction in order to ensure the realization of construction quality objective.
Work - Post Responsibility - Responsibility of Project Manager.
6. Experienced R&D team:
Dasen has a research and development team with 2 ph. D. leading more than 20 high-end R & D technicians. Dasen also owns a sound management process and advanced development tools.
7. Certificates and patents:ISO9001-2015, ISO14001-2015, IATF16949-2016, UL
We obtained more than 30 invention patents and utility model patent and gained the honor: "scientific and technological innovation enterprises", "Jiangxi Province special new enterprises", "national high-tech enterprises".
