Graphite is an ideal material…

… for molded parts in various applications. High heat resistance, excellent conductivity, good lubricating properties and high chemical resistance characterize molded parts made of graphite and make them irreplaceable in many areas of application.

Single parts or series production?

RMC Remacon offers individual solutions for your needs. Here we serve application areas in which graphite moldings are required as individual parts, as well as series with large quantities. n.

From the raw graphite to the molded CNC graphite parts.

On customer request, we offer both finished graphite molded parts and raw graphite parts in defined dimensions, which are adapted and modified for your process according to your specific application.

Useful properties of molded graphite parts

Temperature resistance

Graphite begins to oxidize at high temperatures. The oxidation occurs in air from about 350 – 600°C, depending on the type. However, if the molded parts are used in a non-oxidizing atmosphere, the temperature resistance rises up to approx. 2,500°C, depending on the grade. In addition, they have excellent resistance to thermal shock.

Chemical Resistance

Due to their excellent chemical resistance to non-oxidizing acids, molded parts made of graphite are classified in the group of corrosion-resistant materials. This allows them to be used in various chemical and pharmaceutical processes.

Lubricating effect

Graphite offers self-lubricating properties due to its special crystal structure. This property makes graphite moldings from RMC Remacon an excellent material for use in plain bearings and sealing elements.

Thermal conductivity

Molded parts made of graphite have good thermal conductivity which can reach up to 130 W/m*K depending on the type. This conductivity is far above that of stainless steel or alloys such as bronze or brass.

Production of graphite molded parts

For the production of graphite moldings, raw materials such as petroleum cokes, pitch cokes, carbon blacks are mixed with thermoplastic binders. These are pressed into so-called green bodies, usually in an extrusion process, which are then subjected to sintering at about 1,000 – 1,200°C under vacuum.

This carbonization process ensures an open pore structure by decomposing the binder into volatile components. The subsequent graphitization takes place at 3,000°C and ensures a conversion of the amorphous carbon into polycrystalline graphite.

In order to meet the highest material requirements, RMC Remacon offers not only extruded graphite but also molded parts made of isostatically pressed graphite (ISO graphite). These have significantly better properties in terms of material strength, higher volume density and less porosity. In addition to finer-grained raw materials, a modified pressing process is used during production, which ensures greater strength under high pressure.
