Technology, Production and Quality

Which technical ceramic materials does Rauschert offer, and how do I choose the right material for my application?
Rauschert offers a comprehensive range of advanced technical ceramics including
•    aluminium oxide (Al₂O₃) in various purity grades, including high-purity compositions
•    zirconia (ZrO₂)
•    silicon carbide (SiC) and silicon nitride (Si₃N₄)
•    aluminium titanate
•    ceramic composites such as zirconia -toughened alumina (ZTA) and alumina-toughened zirconia (ATZ)
•    as well as various silicate ceramics.
Selecting the right material helps optimise component performance, extend service life and ensure reliable operation. In addition, we offer multi-material components combining ceramics with metals or plastics, enabling application-specific solutions that utilise the complementary properties of different materials. Our specialists support you in selecting the most suitable material solution to meet your application's technical requirements and cost requirements.

Does Rauschert manufacture custom ceramic components according to customer drawings or specifications?
Yes. Rauschert specialises in developing and manufacturing tailor-made technical ceramic components based on individual customer specifications. We are also able to develop cost-effective ceramic alternatives to conventional metal components, helping customers improve performance, extend service life and reduce overall operating costs. We produce precision ceramic parts for demanding industrial applications, including mechanical engineering, pump technology, electrical engineering, food processing and medical technology. 

Can Rauschert support customers from initial design and material selection through to series production?
Yes. Rauschert provides comprehensive engineering support from initial design and material selection through to prototype and series production. Our capabilities include in-house material development, tooling, ceramic forming and precision machining. Combined with our application-specific engineering expertise, we help customers optimise component performance, manufacturability and cost efficiency.

What tolerances, dimensions and geometries can Rauschert achieve?
Rauschert manufactures high-precision technical ceramic components with complex geometries and, where technically feasible, tolerances in the micrometre (µm) range. In addition, we can achieve application-specific surface finishes and textures, ranging from mirror-smooth surfaces to precisely defined surface roughness and microgeometries, using a variety of techniques:
•    precision machining, including precision grinding and green machining
•    Laser surface structuring
•    Ceramic coatings applied by thermal spraying
•    Glazing for functional and protective surface finishes
Together with our ceramic forming capabilities, including uniaxial and isostatic pressing, ceramic injection moulding and extrusion, these technologies enable us to produce components ranging from miniature precision parts to large industrial ceramic components.

What quality standards and certifications does Rauschert meet?
Quality management is an integral part of Rauschert's development and manufacturing processes. Our quality management systems include ISO 9001 certification at relevant locations. We ensure consistent production quality and reliable industrial processes. For quality control, Rauschert employs advanced inspection and analytical equipment, including scanning electron microscopes (SEM), enabling detailed examination of ceramic microstructures, material properties and potential defects. During project planning we also agree with our customers on appropriate inspection procedures and quality documentation based on their specific requirements.

Commercial Aspects, Logistics and Customer Support

What production volumes can Rauschert accommodate?
Rauschert manufactures ceramic components in quantities ranging from individual prototypes and small batches to high-volume series production.
Our manufacturing capabilities cover all established ceramic forming processes and enable us to select the most cost-effective manufacturing method for each project, based on production volume, component geometry and technical requirements.
What information does Rauschert need to evaluate my application and provide a quotation?
To evaluate your project and prepare a quotation, please provide 
•    a technical drawing or CAD model
•    the required dimensions and tolerances
•    the intended application 
•    and the estimated production quantity. 
Information about operating temperatures, mechanical loads, chemical exposure, wear conditions and other performance requirements helps us assess technical feasibility and recommend suitable ceramic materials. If your design or material selection is not yet finalised, our specialists can support you during the early design stages.

What are the typical lead times for technical ceramic components?
For standard components or established product designs requiring only minor modifications, typical lead times are around three to four months. For complex, highly customised ceramic components, the development process can be significantly longer. Development projects may take one to two years. Once the component design and technical solution have been validated, the transition to series production typically takes around six months.

Does Rauschert supply internationally and provide local support?
Yes. Rauschert supplies to customers worldwide, supported by an international network of manufacturing sites, sales offices and technical specialists. Our international presence includes local sales and technical support contacts in the United States, the United Kingdom, alongside further locations in Europe and Asia.

How does Rauschert ensure reliable supply and delivery for international customers?
Rauschert operates an internationally connected manufacturing network providing flexible production capacities and reliable supply for industrial customers worldwide. Internationally mirrored production capabilities further help reduce dependence on individual manufacturing locations. Drawing on extensive experience in international logistics, Rauschert supports reliable and efficient delivery to customers worldwide. We work closely with our customers to develop tailored logistics and delivery solutions that meet their individual requirements.
