Extruded Zirconia and Alumina Ceramics
What are the advantages of Ceramics:
Hardness and rigidity
Temperature stability
Isolation
Resistance to wear, corrosion, pressure
The disadvantages are:
Very low light transmission
Some limits in shapes
Application of Zirconia and Alumina
Ceramic tubes for UHPLC

Transmissions Shaft for Rotors
Precision Bearings for Instruments
Screws for Isolation
A large variety of technical components are manufactured in SJC according to
Customer design.

Die pressed Parts
SJC pressed parts are produced in a wide variety of different sizes and shapes manufactured to customer’s designs.
However, the tolerances for complex shapes can be limited since pressed pieces have a shrink rate of 15 % to 30 % during the sintering, and further reworking of the product is not always possible.
