JOEST delivers special vibration table for german stainless-steel producer

JOEST Spiral Crusher with Shakeout

Bosch Rexroth is modernizing its existing process of emptying die-casting molds by implementing a new casting-sand separation and recovery plant. Once the casts are freed from their molds, they are separated from the sand which is processed and reused. The task for JOEST was very complex. The focus was on the emptying process of the molds and to break down the sand and clean it. The sand is then returned to the casting process. On site, the machines will be placed in a space that was previously occupied by a furnace. A large chamber in which the furnace used to stand, connects the factory floor to the basement.

Four-way travelling JOEST Charging Vehicle

For the optimization of the foundry and to improve the production process, the Bosch Rexroth AG in “Lohr am Main” is adding a third furnace to its automatic charging system which currently features two furnaces. For this project, a new furnace platform is being built in the neighboring building. The task for JOEST was to find a solution, so that the existing feed equipment for the furnace Charging Vehicles could be reused. The vehicles are fed with metal scraps and additive materials needed for the melting process, both of which are bound to their original location.

JOEST Shakeout with Counter Frame

For a client from the foundry industry based in Croatia, JOEST designed and manufactured a Shakeout. Its frequency and oscillation angle can be adjusted electronically, and this design includes a downstream feeder with dual-lane discharge. The machines were delivered to Croatia during the second fiscal quarter of 2021. Commissioning is performed and overseen by JOEST and is planned for this summer. The client ‘s demand was to provide a reliable Shakeout that could handle a large spectrum of parts whilst maintaining a small form factor due to space limitations on site. The machine should separate as much sand as possible without damaging the casts made of gray cast iron and spheroidal graphite iron. The client’s molding plant type HWS EFA-SD 5 with molding boxes of 1000x920x650 mm produces a maximum of 80 molds per hour. Roughly 2000 different parts are produced, the heaviest weighing 300 kg.

Customer of the Year EN

Atik Metal, one of the largest and most modern foundries in Turkey, producing mainly for export, makes a new investment. The Project includes two new HWS molding plants, the according Eirich sand processing with vacuum mixers and two custom shakeouts followed by manipulator supported cast processing technology. Als Trennrinnen kommen 2×2 Trennrinnen mit elektronischer Schwingparametereinstellmöglichkeit zum Einsatz. Empfindliche Gussteile, die für die Behandlung auf einer Trennrinne nicht geeignet sind, können per Manipulator auf eine parallel verlaufende Softhandlingstrecke übersetzt werden. So werden Oberflächenschäden vermieden. Auf der nachgeschalteten Lese- und Sortierrinne wird mittels Manipulator Kreislaufmaterial vom Gussteil getrennt und dann auf eine Hängebahnstrahlanlage transferiert.
