Our manifold specialty graphite materials are appreciated for their outstanding technical properties and ability to meet the highest requirements in terms of quality, cost efficiency, and eco-friendliness: from achieving extremely high purity to simplifying machining, and saving on flushing gas.
In numerous applications, our specialty graphite products enhance the performance of systems and processes, such as continuous casting, die casting and sintering and degassing systems.
For dies and crucibles, extruded and vibration molded graphites are used, depending on the size. Thermal shock resistance, consistently high purity, and high material density with low porosity guarantee excellent melting processes.
With critical metal alloys in mind, we have developed special isostatically pressed graphites with high mechanical strength and density. We supply them as semi-finished products but also make crucibles and dies from them to suit individual requirements.
Our carbons and extruded, vibration molded, and die molded graphites are highly suitable for the complex molds used to produce railroad wheels and diamond drill bits. These specialty graphites are robust and have a long service life thanks to their material properties. With our comprehensive range of materials, we cover all material property and size requirements.
For efficient degassing processes with maximum purification, gas injection and distribution systems designed to suit specific plant conditions play a crucial role. On the basis of their specific plant parameters, we help our customers design, produce, and operate optimum degassing systems.
We work closely with OEMs supplying the aluminum processing industry. For example, in collaboration with customers, we have developed casting rings made from isostatic graphite R4800 that are used in the production of aluminum billets. Our material was chosen because of its uniform pore distribution.
We supply selected materials for degassing tubes and gas distribution systems used in non-ferrous metal melts. Our SIGRAFINE materials allow plant-specific design of gas injection systems for batch-operated and continuous plants of any size, irrespective of output rate.
For gas injection tubes, SIGRAFINE MTN and HLM should preferably be used. The reason for this is the high oxidation rate. For specific requirements, we supply an additional special impregnation (NOX treatment) that further increases the oxidation protection and lifetime of the materials.
Graphite materials and components are being increasingly used in the metal industry for die casting and sintering processes due to their particular advantages like high resistance to temperature change, extremely high compressive strength, low wettability and adhesive tendency.
