Mould design is today performed by a trial and error approach and by means of skilled technicians. Consequently, the time and the related costs required for a new component to enter in production are high and strongly limit the productive capacity and flexibility of ceramic companies.

To cope with the limitations of the traditional mould design method, an innovative mould design method able to simulate the behaviour of the ceramic material during firing has been developed.

The solutions provided are:

  • a numerical-experimental methodology for determining the material viscosity during firing. This methodology has been object of a European patent filed in June 2011.
  • a numerical simulation model able to predict the shrinkage and the pyroplastic deformations of ceramic components during the production process.
