For many sought-after application functions involving key components, ones made of technical ceramics provide a technologically and economically superior alternative to conventional materials.

Ceramic components for puncturing

Due to the high hardness of the material, ceramic components are very well suited for puncturing.

This hardness reduces wear, thus ensuring perfect functioning for a long time. Injection molding allows you to create pointed, sharp contours already in sintered condition. If necessary, the final sharpness may be increased even further by means of hard machining.

Suitable materials:

  • Al2O3
  • Mixed oxide ceramics
  • ZrO2
  • Si3N4

Application examples:

Puncturing needles for coffee capsules

Outstanding features:

  • hard and resistant to wear
  • hot water resistant
  • corrosion-proof
  • food safe

Ceramic components for guiding

Ceramic guide elements, be it rails, bushes or shafts, are popular in mechanical engineering for guiding abrasive materials with precision and free of friction.

The extreme strength, the chemical resistance and the corrosion resistance of the ceramic elements reduce wear and thus decrease the costly maintenance and repair intervals. Longer machine running times and less production downtimes increase the profitability of the overall plant.

Ceramic components for insulation

Ceramic materials are suitable for use as insulation materials in electrical engineering as well as for thermal insulation.

With its specific resistance of 1012 (at 20°C), Al2O3 is especially suitable for preventing the flow of current or protecting live parts against any contact and the environment. Depending on the material, absorption and release of heat are also relevant for thermal insulation.

Ceramic components for separation

Particularly in chemical material separation applications (absorption, extraction), ceramic components are convincing by their material properties.

They are resistant to wear and high temperatures and in comparison with most materials absolutely corrosion-proof. Applications can be found in laboratory technology, process technology, biotechnology or medical technology, where liquids are moved, mixed, separated or processed in any other way. The ceramic components are used as valve and adjustment discs, mixing elements or cylinders and pistons.

Ceramic components for grinding

Due to their material advantages such as neutral taste, wear resistance and biocompatibility, ceramic grinding wheels will increasingly replace the previously used metal wheels.

Ceramic grinding wheels can also be used for achieving new, more effective cutting geometries.

The grinding mechanism is a functional unit within a system intended for grinding a wide range of materials. The grinding effect is achieved by repeated crushing in an increasingly narrowing grinding gap variable by axial displacement of the rotor or stator. The shearing and/or friction action breaks down the material, which, in the case of aggressive media, can lead to increased wear of the grinding mechanisms.

Ceramic components for spraying

The chemical resistance and a high degree of hardness in addition to the design flexibility of injection molding are the reasons for using these components in many spray applications.

Atomizing, also referred to as spraying, is the splitting of a liquid into fine droplets as aerosols (mist) in a gas (usually air). Various liquids are also sprayed to achieve an even surface coating or a disintegrating effect using pressure (e.g. high-pressure cleaners).

Applications of ceramic components can be found in the coating, medical, cleaning, agricultural and printing sectors.

Ceramic components for cutting

The extreme hardness of ceramic components predestines them for cutting processes.

According to the DIN 8588 standard, cutting or splitting means the partial or complete separation of a part into one or several smaller parts.

Injection molding allows you to create pointed, sharp contours already in sintered condition. If necessary, the final sharpness may be increased even further by means of hard machining.
