Do you have any questions?
Ceramany GmbH offers you a wide range of different ceramics:
oxide ceramics, non-oxide ceramics such as silicon nitride and others.
We are happy to support and advise you on the choice of material for optimum performance.
Our material overview shows you all the properties of the ceramics we use in detail.
We manufacture thread guides and textile components, centering pins, positioning pins, gas nozzles, gas distributors, protective devices, pump elements and many other drawing parts according to your specifications.
As a manufacturer of high-quality series components, Ceramany offers a growing number of standard ceramic components. This allows designers to choose from a diverse standard range of cost-effective off-the-shelf ceramic components (e.g. dowel pins) for their applications.
