MANUFACTURING METHOD OF TECHNICAL CERAMICS

We support all manufacturing processes, so that their product is manufactured according to the best practices, taking into account the price-performance ratio.

The

Terms appearing in the literature such as high-performance ceramics, structural ceramics, construction ceramics, industrial ceramics,

Engineering ceramics, functional ceramics, electrical ceramics, cutting ceramics and bioceramics describe special aspects of technical ceramics.

  • Raw materials and powder

    Fundamental requirements of production and the most economical manufacturing process determine the choice of raw materials according to (type, purity, grain size and specific surface) as well as other auxiliaries.

    • Alumina

    • Zirconium oxide

    • Silicon nitride

    • Silicon carbide

  • Mass preparation

    The ceramic manufacturer purchases the raw materials and carries out all further processing steps himself or the ceramic manufacturer obtains processable materials and begins the ceramic process with shaping.

    • Grind

    • Mix

    • Filter

    • Granulate

    • Plasticizing

    • Spray drying

  • Engineering

    When solving a technical problem, the engineer or designer must design technical elements. In the case of ceramic materials, he must pay particular attention to the required construction appropriate for the material.

    • Determine requirements

    • construction

    • Technical drawing

    • application

    • Determine quality

    • Determine the manufacturing process

    • Determine prices

    • Set quantities

    • Determine material (Al2O3, ZrO2, SiC, Si3N4)

    • Send offer

  • Shaping

    Here, the powder particles are compressed and brought into a coherent shape that has sufficient strength for subsequent handling.

    The selection of the suitable shaping process is usually based on economic considerations (rational production).

    • Dry pressing

    • Extrude

    • Foil casting

    • Injection molding

    • Micro injection molding

    • Isostatic presses

    • 3D printing LCM

    • Alumina

    • Zirconium oxide

    • Silicon nitride

    • Silicon carbide

  • Green processing White processing

    Green processing takes place on dried components that still contain organic additives.

    Whitening is carried out on pre-fired components that are free of organic additives. The firmness is determined by the pre-firing.

    • Milling

    • Rotate

    • Drill

    • Sawing

    • grind

    • Lapping

    • polishing

    • Honing

    • Metallize

    • Glaze

    • Assembly

    • substitution

    The

  • Finishing

    Hard machining

    Finishing or hard machining is carried out on burned components that have already been brought as close as possible to the final dimensions through the shaping, green or white machining. The narrowest tolerances can be realized by ablating finishing processes.

    • grind

    • Lapping

    • polishing

    • Honing

    • Metallize

    • Glaze

    • Assembly

    • substitution

    • ...

  • Quality inspection

    Consistent quality is based on qualified manufacturing processes, the regulations and results of which are routinely monitored and logged.

    • Visually

    • Dimensional check

    • Crack test

    • Strength test

    • Roughness test

    • Insertion test

IMPROVEMENTS WITH TECHNICAL CERAMICS

TECHNICAL CERAMICS IS THE MATERIAL OF THE FUTURE

 

Why?

To date, ceramics have been considered in a large number of new applications in which high hardness, high wear resistance, high corrosion resistance and good high-temperature stability combined with low specific weight are required.

The new high-tech materials achieve high strength. Their values ​​are comparable to the values ​​of metals and generally exceed all polymers.
The properties of the ceramic materials are largely determined by the respective structure or the microstructure. Through the targeted setting of certain microstructures, the so-called microstructure, the mechanical and physical parameters can be influenced in different directions.

An important aspect to consider when using ceramics is always: "Ceramics are brittle"!

 

Due to their ductility, metallic construction materials are "balanced and good-natured" materials that sometimes forgive lighter design errors (error tolerance) because they are able to reduce local stress peaks through elastic and plastic deformation.

In addition, the metals are usually characterized by good electrical and thermal conductivity and by characteristic values ​​that are independent of the spatial direction.

 

Ceramic materials, on the other hand, are usually electrically and thermally insulating, have a high hardness and can have a very low thermal expansion. Due to the lack of plastic deformability, they are also extremely dimensionally stable.

 

Compressive strengths can be achieved that can be ten times the bending and tensile strength. Compared to metals, ceramics are particularly suitable for use at high temperatures, since the characteristic values ​​of the ceramic materials are influenced far less by temperature loads and only at higher degrees than those of the metals. Ceramics are similarly positive in terms of corrosion and wear.

 

Because of these advantages, we encounter technical ceramics at every turn. Many household appliances would not work without ceramic insulating parts. Likewise, a reliable power supply would not be conceivable without insulators and fuse components made from technical ceramics.

 

Ceramic substrates and components form the basis for components and assemblies in all areas of electronics, and in mechanical and plant engineering, sliding and regulating elements ensure wear and corrosion-free function.

 

Ceramic is indispensable as a construction and insulation material in industrial furnaces in high temperature technology! These few examples already clearly show that technical ceramics play an important role in our world.


However, ceramic components are usually not visible at first glance. Nevertheless, they play a decisive role in conventional applications and also in innovative products, such as in dental technology with dental implants and in the luxury goods segment with black zirconium oxide ceramic watch cases.

 

The potential of technical ceramics has not yet been exhausted.
