Adamou uses Ceramic Injection Moulding route to produce valve seat
A Ceramic Injection Moulded valve seat produced by Adamou Sàrl
Adamou Sàrl of Etoy, Switzerland, is using ceramic injection moulding (CIM) to produce a sintered valve seat from 99.9% alumina powder. The company states the ceramic seat is used in conjunction with a ceramic ball to open and close a valve in order to achieve a high precision flow rate for homogeneous liquid mixing in a chemically aggressive environment. Different valve seat dimensions are produced depending on the flow rate required and customer specification.
Key to the success of this application is producing the CIM valve seat to dimensional tolerances in the micron range, thus avoiding any leakage after the valve is closed by the use of the ceramic ball, states Adamou.
In addition to alumina CIM, the company also produces CIM parts from black or coloured zirconia, and recently launched a new website.
