TECHNICAL CERAMICS MANUFACTURER

There are different manufacturing processes for technical ceramics that can be used depending on the type of end product desired and the specific needs of the application. Here are some of the most common procedures:

  1. Pressing: This is the most common method used to produce technical ceramics. It involves compacting powdered raw material into a shape using a combination of pressure and heat. The resulting ceramic can then be processed further, for example by sintering, pressing or cutting.

  2. Injection molding: This is a process used to create complex ceramic parts. It involves injecting ceramic powder into a mold under high pressure and heat. The resulting part is then usually still sinterable and must be further processed.

  3. Extrusion: This is a process where the ceramic is forced through a die to create a shape. It is often used to produce tubes, rods and other long parts.

  4. Spray drying: Here, liquid ceramic material is sprayed into a fine powder, which can then be dried and compacted. This process is often used to produce thick layers or coatings.

  5. Sol-gel process: This is a process for producing dense, smooth surfaces. It involves the transformation of liquid material into a solid ceramic through controlled chemical reactions.

  6. Hot pressing: This is a process for producing complex ceramic parts from raw material that has already been sintered. It involves applying high pressure and temperature to the ceramic material to shape it.

These are just some of the processes that can be used to produce technical ceramics. The choice of process depends on various factors, such as the type of end product desired, the quantity and the requirements of the application.

Raw materials and powder

Basic requirements of production and the most economical manufacturing process determine the selection of raw materials (type, purity, grain size and specific surface) as well as other auxiliary materials.

  1. Alumina

  2. Zirconium oxide

  3. Silicon nitride

  4. Silicon carbide

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).

  1. Dry pressing

  2. Extrude

  3. Foil casting

  4. Injection molding

  5. Micro injection molding

  6. Isostatic pressing

  7. 3D printing LCM

  8. Alumina

  9. Zirconium oxide

  10. Silicon nitride

  11. Silicon carbide

Qualitaetskontrolle technische Keramik

Mass preparation

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

  1. Grind

  2. Mix

  3. Filter

  4. Granulate

  5. Plasticizing

  6. Spray drying

Green processing White processing

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

The white processing takes place on pre-fired components that are free of organic additives. The strength is determined by the pre-firing.

  1. Milling

  2. Rotate

  3. Drill

  4. Saws

  5. grind

  6. Lapping

  7. polishing

  8. Honing

  9. Metallizing

  10. Glazing

  11. Assembly

  12. substitution

Engineering Tätigkeiten

Engineering

In 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 material-specific design.

  1. Determine requirements

  2. construction

  3. Technical drawing

  4. application

  5. Determine quality

  6. Determine the manufacturing process

  7. Determine prices

  8. Define quantities

  9. Determine material (Al2O3, ZrO2, SiC, Si3N4)

Finishing

Hard machining

The final processing or hard processing takes place on completely fired components, which have already been brought as close as possible to the final dimensions through the shaping, green or white processing. The tightest tolerances can be achieved by removing finishing processes.
