Graphite and C/C Components for the Manufacture of Container Glass

Graphite is a very versatile material with a wide range of applications, especially in the industrial hollow glass and container glass industries. We provide innovative solutions:

• C/C conveyor channel systems move rapidly and flexibly in mold filling and do not require coating with a special finish/paste or spraying with oil thanks to their good antifriction properties. The gob surface remains undamaged.
• Carbon molds combine the advantages of wood molds with those of graphite. The porous structure stores water that forms a moisture vapor film as the molten glass is introduced. During the actual glass blowing process, the vapor formed ensures freedom of contact between the graphite and the melt. Even very fine details and low tolerances are no problem.
• Graphite contact elements, such as grippers or guides made from isostatically pressed graphite, transport the hot fragile glass products to the dead plates and cooling ovens.

Our specialty graphites are impact-resistant, thermally stable, and resistant to thermal shock and corrosion. In addition to favorable porosity and good antifriction properties, they also offer application-tailored thermal conductivity and low wettability and adhesion in contact with molten materials. They are therefore outstandingly suitable for machine components in the container glass industry and stop contamination as well as surface and mechanical damage.

Thanks to their high flexural strength, even at elevated temperatures, our isostatically pressed graphites and C/C, in particular, reliably prevent cool spots on lying surfaces and glass distortion.

We provide support for our customers based on our comprehensive expertise with materials and our long-standing experience with a wide range of applications. In material selection, numerous criteria need to be taken into account, such as accurate replication of detail, service life, combustion behavior or component size. Our SIGRAFINE and SIGRABOND materials ensure optimum results and eliminate the need for internal cool coatings and special surface treatments.

Our Product Finder for SIGRAFINE Fine-Grain Graphite can help you pre-select the appropriate graphite grades for your application.
