Extruded Graphite Mold
Extruded Graphite Mold is available in Blocks and Rods having the following grades:
- BC – BC is baked Carbon (Amorphous) materials available in various shapes & sizes
- GLM-E – GLM-E is competitively priced graphite with fine particle size, good uniform structure and is primarily used for general applications
- GLM-50 – GLM-50 is a denser version of GLM-E. It is characterized by higher density and better strength. It finds wider use for general applications
- GLM – It is a denser version of GLM-50 and is characterized by higher density, higher strength and lower porosity. It has a finer structure and can be machined to a fine finish. It can be used for most applications
- GLM-S – It is a still denser version of GLM and is characterized by very low porosity
Graphite India produces fine grain extruded graphite small diameter rods. Diameters range from 3 mm to 65 mm with a maximum particle size of 0.2 mm. Mini rods are manufactured in two grades - GMMR-50 and GMMR. GMMR-50 is used for general applications. GMMR is a denser version of GMMR-50 used for applications requiring higher strengths and lower porosity.
GMT – This grade of graphite is produced as tubes for fluxing and other applications.
The above grades exhibit excellent properties like, good thermal conductivity, low electrical specific resistance, low co-efficient of thermal expansion, good chemical inertness and can be easily machined.
AX Treatment – All the above grades can be subjected to special AX treatment to retard oxidation and thereby effectively extending its life.
Heat Exchanger Tubes
Heat Exchanger Tubes are available in all Standard Sites up to a length of 4000 mm. These tubes are manufactured through Extrusion process and exhibit excellent heat transfer, mechanical and chemical properties.
Moulded Mold Graphite
These are biaxially pressed Carbon & Graphite products.
These grades of graphite have a fine structure and molded using compression presses. They have excellent strength properties and mechanical properties better than extrusion pressed graphite products. They possess good thermal conductivity, low electrical specific resistance, low co-efficient of thermal expansion, and very good machinability.
- AMOR - Carbon
- DXT - Partially Graphitised
- XN - Graphitised
- DXN - Denser version of XN
Isostatically Processed Graphite comes in fine grain and exhibits good isotropism with homogeneous structure, high density, strength, Low specific resistance, easy machinability , high thermal shock resistance. Typical applications are Semiconductor, Solar, Vaccum Furnace, Continuous Casting, Diamond, Heat Shields, crucibles, EDM.

In many chemical processes, the apparatus and reaction vessels must be protected against the Acidic and Caustic materials used . Apparatus linings made from Ceramic or Synthetic Plastic type materials are often unsuitable, since they may not withstand Chemical Attack, High Temperatures or sudden temperature changes. Alkaline solutions and Hydrofluoric Acid are of great importance in chemical technology, but they rapidly destroy equipment linings. Chemical resistant Carbon Bricks are suitable for service in Phosphoric, Sulfuric or Hydrochloric Acids, as well as in Caustic applications involving Sodium or Potassium Hydroxides and other strong bases.
These bricks are produced from selected raw materials to offer unique combination of properties such as high Thermal Shock Resistance, low Co-efficient of Thermal Expansion, High Abrasion, High Corrosion Resistance. These properties combined with the inert and non-sticking nature make Carbon Bricks ideal lining materials for chemical and metallurgical application.
