PHT200 Isostatic Powder Press for Tableware

Our isostatic powder press PHT200 is used for the efficient forming of bowls, mugs and cups with handle made of ceramic granules (e.g. porcelain, hard porcelain, stoneware and bone china).

Closing force, hydraulic system and installation space of the press have been optimized for the production of mugs and cups with handle 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.

The system consists of two pressing heads, each of them operating one pressing tool in overlapping cycles.  A horizontal pressing cylinder closes off the two tool halves while the granules are being compacted isostatically. After the pressing process, a robot takes the article out of the pressing tool and passes it on to a fettling machine.
