Method for producing closed ceramic hollow items, in particular jug lids for hotel porcelain, and device for carrying out the method

摘要

A method for producing closed ceramic mouldings and a device for carrying out the method, in particular for jug lids of hotel porcelain, by means of automated slip-casting using known casting devices and suction stations. According to the invention, the casting mould is divided into a top part and a bottom part, and the bottom part is cast first, a defined quantity of residual slip remaining in the mould. Following the first body-forming process, the top part is fitted on, an opening is introduced into the bottom part for pressure compensation, the casting mould is turned through 180 DEG and the top part of the jug lid is thus formed by the quantity of residual slip. After being dried, the closed blank of the jug lid is removed without having to be fettled IMAGE
