For our customers in the glass and refractory industries, everything revolves around the melting and molding processes. With the increasing demands on material purity, surface quality, precision, design, energy and cost efficiency, the requirements for components and systems are becoming ever more challenging. The focus is increasingly on specialty graphites.
Our portfolio makes it possible to use optimized materials, such as very lightweight components produced from SIGRABOND carbon fiber-reinforced carbon (C/C), which relieve the mechanical system.
We can also support you in the development, analysis and optimization of your products and processes with engineering and calculation.
Components
Our optimized machine components and high- performance materials make us many leading companies’ partner of choice.
Graphite and C/C Components for the Manufacture of Container Glass
No matter whether producing technical glass, laboratory glass, inspection glass or domestic glass, the key requirements after the melting process are dimensional accuracy, optical perfection, purity, consistent quality, and physiological safety. Our carbon fiber-reinforced carbon (C/C) products and isostatically pressed specialty graphites play an important role in achieving the best results in a cost-effective manner.
Graphite Profiles and Barriers for the Manufacture of Float Glass
Float glass requires consistent high quality, absolute precision, flawless appearance, and the highest purity possible. Our materials and components for the continuous manufacture of large-format float glass are impressive in every respect.
Graphite Casting Molds for the Refractory Industry
In addition to thermal stability and thermal shock resistance, our graphites also offer high impact strength, wear resistance, and mechanical strength as well as excellent corrosion resistance. Moreover, they feature low wettability and adhesion in contact with molten materials. Material properties like these make our graphite quick and easy to machine. Optimum design for molds and ovens in the glass industry.
