PH450 Isostatic Powder Press for Tableware

Our isostatic powder press PH450 is used for the efficient forming of flatware, bowls and ovenware made of ceramic granules (e.g. porcelain, hard porcelain, stoneware and bone china).

Closing force and installation space of the press have been designed to cover the full range of different article sizes as used in customary tableware series with our DORST tool system being suited to a wide variety of article shapes. The geometry of the article as well as reliefs, inscriptions and logos will be reproduced in a very precise way.

 A horizontal pressing cylinder closes off the two tool halves while the granules are being compacted isostatically. After the pressing process, the article slides over a skirt and onto the article transport system to be transported to a fettling machine.
