Graphic element Assessing raw materials for the pressure casting and fast firing of sanitaryware ceramics
     
 
The performance requirements of clays and kaolin, casting slips and filtering support were tested to establish the material characteristics best-suited to pressure casting and fast firing.
 

New pressure casting and fast firing processes are rapidly replacing more conventional methods for ceramics production, especially in the dinnerware sector. The new processes are more streamlined and therefore less tedious, and they can be automated, reducing time lags to a minimum, but they have yet to be applied in the production of larger ceramic parts like sanitaryware.

The aim of this project was to understand better the performance requirements of raw materials for the new ceramics manufacturing processes known as automated pressure casting and fast curing. Work consisted of developing casting slips and filtering support adapted to the new production methods. Clays and kaolin were studied and the casting and firing processes were assessed using the developed raw materials. The project established the mineral characteristics best-suited to the applications in question.

Cost savings are substantial for the manufacturing partner, as the firing of 20% lighter end-products require less energy. The significant reduction in costs will allowed production to remain in Europe rather than moving to countries with lower labour costs. For the raw material supplier, the gains are in the ability to understand better end-user needs and to evolve towards the supply of better formulations.
