Ceramic Industry

Traditional methods of manufacture of ceramic holloware and large sanitaryware items rely on slip and pressure casting using Plaster of Paris or porous resin moulds. These methods are slow and not flexible enough to allow manufacturers to exploit rapidly changing trends in markets and design. Traditional manufacturing methods cannot accommodate the mass customisation which will be demanded by future markets.

FLEXIFORM was a major, international project to develop a revolutionary approach to pressure casting of ceramic shapes. This project has been successfully completed end of 2004 by nine European companies, were PORTEC was the task leader of mould material development within the consortium. The aims of the FLEXIFORM project were to enhance the flexibility and agility of pressure casting for holloware and sanitaryware items through use of novel mould materials which can be direct CNC machined. This will lead to faster casting, enhanced quality, easier handling of moulds and cast items, and much shorter design to product lead times.
