PRODUCTION METHOD THE TECHNICAL CERAMICS

Technical Ceramics Manufacturing: A wide variety of manufacturing processes are used in the production of technical ceramics to meet the requirements of the end product and its application. Here is an overview of some of the most common processes:

These processes are just a few examples of how technical ceramics are manufactured. The selection of the appropriate process depends on various factors, such as the type of end product, the required quantity, and the specific requirements of the application.

Pressen von technischer Keramik

Pressing is the primary method used to manufacture technical ceramics. It involves compacting powdered raw material using pressure and heat. The ceramic can then be further processed, for example through sintering, pressing, or cutting.

CIM Ceramic Injection Molding

Injection molding enables the production of complex ceramic parts. In this process, ceramic powder is injected into a mold under high pressure and heat. The resulting part typically requires additional sintering and further processing.

Ceramic Extrusion

Extrusion is often used to produce tubes, rods, and other elongated ceramic parts. In this process, the ceramic material is forced through a die to create the desired shape.

Spray drying

Spray drying is used to produce thick layers or coatings. In this process, liquid ceramic material is atomized and then dried and compacted.

Sol-gel process

The sol-gel process enables the production of dense and smooth ceramic surfaces through controlled chemical reactions.

Hot pressing

In hot pressing, complex ceramic parts are produced from pre-sintered raw material. The ceramic material is shaped under high pressure and temperature.

PROCESS STEPS THE TECHNICAL CERAMICS

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.

Alumina
Zirconium oxide
Silicon nitride
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).

Dry pressing
Extrude
Foil casting
Injection molding
Micro injection molding
Isostatic pressing
3D printing LCM
Alumina
Zirconium oxide
Silicon nitride
Silicon carbide

Quality inspection

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

Optically
Dimensional check
Crack testing
Strength test
Roughness testing
Screwing test
Surface inspection
Hardness test
...

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.

Grind
Mix
Filter
Granulate
Plasticizing
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.

Milling
Rotate
Drill
Saws
grind
Lapping
polishing
Honing
Metallizing
Glazing
Assembly
substitution

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.

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.
