Schunk is not only associated with high-quality materials and components, stable quality, safety and perfection with tradition; Schunk represents much more. The will to tackle problems differently and to strike new paths, as well as the passion for finding new solutions, are the driving forces. Our motto for the future is innovation.

With regards to expertise and top quality, we always prove ourselves to be a reliable partner. In the future, we will show even more clearly how our extensive knowledge is used to turn our components into indispensable elements for countless efficient technologies, machines and devices.

Innovative technology for extreme temperatures

Schunk Kohlenstofftechnik GmbH specializes in the development of materials for the achievement of form, stability and resistance to extreme temperatures.

As an innovative provider of materials and products for the entire spectrum of modern crystal growing systems, Schunk supports its customers on their cost-intensive journey from raw materials to energy-supplying solar modules.

Our key areas of expertise include the manufacture, cleaning and coating of graphitized materials and carbon fiber reinforced carbon (C/C) for use at high temperatures.

Schunk heating and crucible systems made from graphite and C/C are used in current procedures for manufacturing silicon crystals. These systems are used to smelt and store raw material within the multi-stage processes for producing polycrystals and monocrystals.

Individual solutions for the highest temperatures and complex geometries

In addition to plate geometries, Schunk Kohlenstofftechnik GmbH also produces rotationally symmetric components.

Our C/C wound components are used primarily in the solar and semiconductor industries, where we are successfully positioned for high mechanical and the highest purity requirements.

After final dimension processing, our C/C wound components are subject to further finishing stages depending on their intended use.

Our strength lies in high-volume components with large surface areas. Targeted expertise and many years of experience make us one of the few providers worldwide with the ability to produce almost all components in maximum dimensions.

Our C/C manufacturing process is internationally renowned for customized materials with a very high level of stability and low density. In addition, we offer the utmost in process stability for every customer-specific requirement.

Our long-standing experience in the field of graphite and C/C refinement enables both the manufacture and targeted refinement of high-volume components. Using silicon carbide and pyrocarbon coating procedures, we are developing basic materials to be used in new areas of application.

Support from the first idea to manufacturing

We accompany our clients during the entire planning and development process. In this way, many application and client-specific problems can be solved in the early stages through the use of computer simulations. We offer support both in the design and dimensioning of components, and also in choosing the most economic form of production.
