A unique material.

maxon develops and manufactures customizable CIM (Ceramic Injection Moulding) components in Sexau in the south-west of Germany. Our development and engineering program is based on more than 20 years experience in Powder Injection Moulding (PIM) and we work with the most up-to-date CAD technology and finite element calculation. Thanks to CIM, maxon is well-placed to produce highly complex ceramic components - providing extreme precision and supreme quality.

Scope of applications CIM (Ceramic Injection Moulding)

Clock technology

The small components of a clock mechanism have to be constructed with the utmost precision to ensure reliability. With ceramic components the intermeshing parts will maintain the same level of precision for generations to come.

Medical technology

Medical technology places particularly high demands on the materials used in medical devices (e.g. endoscopes): Only optically perfect, high quality, reliable components make the grade. In addition, materials must also be biocompatible and resistant to bodily fluids.

Measurement technology

Ceramic withstands adverse conditions. When used in sensor housings, it demonstrates resistance to high temperatures, abrasive gas flow dust, and chemically aggressive condensate. Its low thermal conduction protects the electronics inside the sensors. Its passive behavior in electrical and magnetic fields allows electronic sensors to be deployed.

Industrial automation

Machine and plant availability is extremely important in the industrial sector. Ceramic impresses here with its hardness, stability, wear-resistance and outstanding sliding characteristics. A prime example of this is maxon's ceramic spindle with its cgs (ceramic glide surface). Sockets/connectors, guides, axles and shafts are also typical ceramic insert elements. The chemically resistant and non-magnetic material can also be used where other materials reach their limits.

Audio technology

Ceramic surfaces impress with their scratch-resistance and surface shine. Its low thermal conduction means ceramic is warm and pleasant to the touch. The continuous development of our forming and polishing processes achieves a very special combination of aesthetics and functionality. Ceramic housings protect the high-quality technology inside and present a high-quality exterior which lasts.

There are no compromises in the pursuit of the perfect listening experience: All the elements need to work in perfect harmony. Our ceramic components are ideal for innovative customised turntable bearings. The use of ceramics means that challenges such as magnetic fields and precision radial run-out are easily overcome. The demands in the high-end range are extremely high: Extreme precision and the highest quality in materials, manufacture and surface finishes always come first. Smooth working relationships based on trust are paramount in ensuring a first-class high-end product.

Drive technology

In drive technology, the limitations of traditional materials can become evident, depending on the application involved. So, for example, customised underwater drives require salt water resistant materials.
