Our isostatically pressed graphite grades in the HCI-Series® are manufactured using the cold isostatic pressing process (CIP).

Isostatic pressing ensures a very fine, even grain structure in all directions. This production method is very different from extruded graphites, in which the material is pressed through a mould, resulting in great dependence on direction.

Technical properties are greatly improved using the CIP process. Strength values are significantly better. The iso-graphites in the HCI-Series® also have excellent corrosion resistance as well as high thermal resistance.

 

Our HCM-Series® has a wide variety of graphite grades that can be selected individually depending on their intended use.

In general, die-pressed graphite grades offer a wide range of technical properties in terms of mechanical strength, friction, density, hardness and electrical conductivity. These properties can also be adapted using special impregnation techniques.

 

 

 

 

 

 

 

Our HCV-Series® has a wide variety of both extruded and vibration-compressed graphite grades.

Vibration-compacted graphite has slightly lower strength values than isostatically pressed graphite, but it is characterised by higher thermal and electrical conductivity. These types of graphite are particularly interesting for casting processes, degassing systems and the carbide industry.
