Porous mould for ceramic slip components - is filled with laminar flow slip and pressurised after closing

The green hardness blanks are made of liq. ceramic slip materials by injection into moulds. The mould wall filters out the liq. and retains the ceramic solid particles on the porous mould wall. The moulding arrangement ensures correctly moulded components which are made rapidly. The ceramic material is injected into moulds at such a speed that laminar flow is maintained during the whole mould filling process. Pressure is built up after completion of the filling process in the cavity of the closed mould. This subsequent pressure corresponds to the closing pressure of the mould. A pulsating pressure can be superposed to the closing pressure.
