Components at their best

Our possibilities in terms of materials, manufacturing processes and finishing are almost unlimited. You should take advantage of this. If you wish, send us an exposé with your requirements or a technical drawing. We find the best solution for you. If you like, also a prototype at short notice.

Our material portfolio

Aluminium oxide

AI203

The material has a uniquely diversified range of applications because of its numerous degrees of purity. We offer aluminum oxide with a purity ranges from 96.0% to 99.8%.

Application

  • Wear parts for the textile and the machine engineering industry
  • Suitable for high temperatures and corrosive environments, e.g. in laboratories
  • Insulating parts for electronics and electrical engineering

Properties

  • Electrical insulation
  • Thermal resistance
  • Resistance to thermal shock
  • Hardness
  • Pressure resistance

Zirconium dioxide

ZrO2

Zirconium dioxide has the unique feature that it impedes the spread of cracks through the so-called transformation toughening mechanism. No other ceramic material shows such a high fracture toughness combined at the same time with such high stability.

Application

  • Sensor Technology (lambda sensors) for oxygen ion conduction
  • Components that face frequent temperature changes, e.g. draw dies and high-temperature insulating parts
  • In cases where high fracture toughness is required, e.g. for medical instruments

Properties

  • Thermal insulation
  • Thermal resistance
  • Flexural Strength
  • Electrical insulation
  • Fracture toughness

Alumina Toughened Zirconia (ATZ)

ATZ

With this kind of mixed ceramic, a small amount of aluminum oxide is added to the zirconium oxide to significantly improve the wear-resistance, elasticity and toughness.

Application

  • Bearings and guide parts for machine engineering
  • Medical implants

Properties

  • Thermal insulation
  • Flexural Strenth
  • Electrical insulation
  • Temperature and thermo shock resistance
  • Fracture toughness

Zirconia Toughened Alumina (ZTA)

ZTA

With this mixture of ceramics, a small amount of zirconium dioxide is added to the aluminum oxide which significantly improves the hardness and stability and simultaneously increases the toughness.

Application

  • Cutting materials for machine
  • Valves, gear wheels
  • Sensors
  • For highest mechanical loads

Properties

  • Hardness
  • Resistance to pressure
  • Resistance to thermal shock
  • Reistance to temperature
  • Flexural Strenth

Steatite

Steatite

Steatite belongs to a group of silicate ceramics and is composed of magnesium silicate. Because of its excellent processability, the material can be produced economically.

Application

  • Isolators and fuses
  • High frequency technology
  • Especially used in the electronics and automotive industry

Properties

  • Thermal insulation
  • Electrical insulation
  • Resistance to thermal shock

Manufacturing process

One employee operates two machines that additively manufacture technical ceramics.

Ceramic 3D printing

The highly innovative 3D printing process at Bosch Ceramics is ideally suited to the rapid and uncomplicated series production of fully operational components. The process requires merely a CAD model and thus enables greatly reduced development times (time-to-market).

Ceramic Injection Moulding (CIM)

Bosch Ceramics' many years of experience in ceramic injection moulding have resulted in continuous improvement of the process chain: The right choice and preparation of materials, suitable mould technology, precisely controlled injection parameters and an exact knowledge of the thermal processes ensure high quality and high precision, even for large quantities.

Presses

Even when pressing is used as an economical mass production process, excellent tolerances can be produced: The achievable accuracies are almost comparable to those of components made from ceramic injection moulding.

More functions desired?

Five stages in the production of technical ceramics are symbolically represented by a ceramic powder, some feedstock, a green part, a sintered part and a finished assembly with electronic components.

Ceramic systems

We are happy to manufacture ceramic components for you. However, we prefer to work with you to develop system applications that integrate technical ceramics into the application, for example with assembly and joining technology or surface finishes. This saves you further processing steps and, to be honest, is also more fun for us. Contact us.
