CERBERITE ® Hot glass handling hardware and consumables
Carbon and graphite tools for hollow glass industry Thanks to its unique combined expertise of graphite materials, C/C composites and carbon felt insulation, Mersen is able to propose solutions for the high temperature methods used in the glass processing industry. CERBERITE® is a complete range of systems and solutions dedicated to hollow glass production lines. The use of graphite and C/C composites have become major elements in these production lines, as these materials offer numerous advantages:
Their contact does not damage hot glass. They are entirely resistant to thermal shocks. They are self-lubricating. They offer better resistance to wear. They have lower thermal conductivity than metals.
Mersen's CERBERITE® solutions thus combine metal supports and carbon consumables. The design of these systems thus offers numerous advantages, such as:
rapid disassembly of worn expendables. easy access on the production line. a design developed with the main equipment manufacturers. high mechanical properties at high temperatures.
Finally, owing to standardised equipment, Mersen's international network can meet your maintenance requirements throughout the world.
High strength graphite for pressure sintering Mersen graphite is very widely used in pressure sintering processes. It enables the fabrication of sintering moulds which in turn are used to produce diamond or ceramic cutting tools, and ceramic armour elements for military applications.
Our customers particularly appreciate the excellent performance characteristics of Mersen iso-moulded graphite in these high-temperature processes.
The combination of exceptional thermal conductivity and a low coefficient of thermal expansion is an essential element to ensure the dimensional stability of sintering moulds.
A well-controlled coefficient of thermal expansion Understanding changes in the coefficient of thermal expansion is very important when designing a sintering mould.
Our grades have been studied over a wide range of temperatures and offer remarkable stability.
A selection of grades according to applications The material used to manufacture a sintering mould is selected based on the process temperature and pressure requirements.
Some of our grades are selected when the material's electrical and thermal conductivity are the prioritised parameters in order to reduce cycle time.
When the process pressure is too high, the mechanical strength of the mould is prioritised.
Our experts are at your disposal to discuss the best grades adapted to your specific needs.
Ellor®: high density isotropic graphite blocks and blanks for your EDM electrodes Mersen, a world leader in the field of isotropic graphite, offers a complete range of ELLOR® graphite grades to suit all EDM applications. Graphite has many advantages, making it the most widely used material for EDM electrodes:
Resistance to thermal shock. Low coefficient of thermal expansion and excellent geometric stability. Machinability. Low wear during sparking.
Mersen is able to recommend the best grade with the best quality/performance ratio based on its customers' unique requirements.
OUR RANGE OF EDM GRAPHITE
ELLOR® +18 A medium density graphite for semi-finishing and roughing operations in the least amount of time and at minimum cost.
ELLOR®+20 A graphite for both roughing and finishing operations. Ideal for manufacturing plastic moulds.
ELLOR®+25 The greater density of this grade provides a better surface finish and its mechanical properties enhance the service life of electrodes. A graphite for universal use.
ELLOR®+30 +40 The surface finish is better and electrode wear is always the lowest.
ELLOR® +50 The very fine structure of these materials associated with their high density allows them to produce very precise machining details and a remarkable surface finish, whilst reducing electrode wear.
ELLOR® DS4 The very fine micro-grain structure of this graphite offers unequalled precision and performance.
Our application experts are at your disposal to provide the support you need in understanding the impact of your machine's configuration and to determine the most efficient parameters.
1891 - 1892: Origins La Compagnie Lorraine de Charbons pour l’Electricité was set up in the Moselle region of eastern France in 1891. It originally manufactured electric motors, dynamos and street lamps before producing coal for electric lighting purposes. Concomitantly, Le Carbone, which was founded in 1892 in the Paris region, produced brushes for electric motors. In 1893, Charles Street, an engineer at Le Carbone, discovered and patented the carbon graphitation process making it possible to manufacture graphite synthetically. This was the first major innovation in the future Group’s history.
1937: Formation of Carbone Lorraine Carbone Lorraine SA was formed in 1937 from the merger of both companies. This merger helped both companies not only to continue pursuing their business activities but also injected them with fresh impetus from a scientific and technical standpoint. This move to pool their expertise was to give rise to products with a bright future.
International development From its creation in 1937 until the eve of the Second World War, the Company enjoyed a remarkable expansion, growing from the size of a SME to an international group. It was very fast off the block in terms of international expansion, demonstrating its pioneering qualities and ambition. Since then, it has stepped up its expansion right around the globe and particularly in Asia over recent years. The Group currently has manufacturing facilities in over 40 countries.
Expansion The Group has expanded relentlessly through a combination of organic growth and acquisitions. Past acquisitions have strengthened its global positions in each of its business segments, enabling it to expand its product portfolio and its geographical coverage considerably. It is now the world leader in graphite anticorrosion equipment, brushes for electric motors and fuses for power semiconductors, and number two worldwide in high-temperature applications of isostatic graphite and industrial fuses.
Strategic repositioning Throughout its history, the Group has stood out through its ability to invest in up-and-coming markets. Over the past decade, it has resolutely pursued a strategy based on four growth drivers, i.e. sustainable development, Asia, selective acquisitions and innovation. It now aims to gain recognition as a leading industrial player in all its markets (energy, transportation, electronics, chemicals/pharmaceuticals and process industries) and particularly in alternative energies.
May 2010: Carbone Lorraine changes its name to Mersen The Annual General Meeting of the Shareholders approved the change in the Group’s name to Mersen to embody its new business profile.
