JOEST delivered the complete vibrating machines to Trakya Dokum’s new smart foundry in Turkey. The plant is designed for the production of various automotive cast iron parts in a vertical flaskless molding line.
The molding line is a DISA 270A; mold dimensions 950 mm x 700 mm, operated at 400 moulds/hour, 150 t/h sand throughput in average, 12 t/h liquid metal in average with inductotherm dual track melting furnace.
After the SBC (Synchronized Belt Conveyor), the molds dump on a reversible conveyor and pass on a shakeout with adjustable frequency and adjustable vibrating angle directly. This soft handling track is for fragile parts which cannot be processed in a rotating drum.
The main track directly connects end of molding line SBC, shotblast machine, grinding area and melting shop in a straight way. After the SBC, the molds dump on a reversible conveyor and pass to a 25 m inclined linear sand/casting conveyor and a 90° curve which follows this conveyor. Conveying the parts on such a long distance together with the sand allows heat dissipation from the castings to the surrounding sand mass flow.
This conveyor arrangement is followed by a rotating drum without any grids and a shakeout with adjustable frequency and adjustable vibrating angle in order to clean the casting surface from sand, reducing sand lump size, and finally draining the dissolved sand through the grids.
After the shakeout, the castings pass on a primary sorting conveyor for removing the downsprue, runner and riser before they enter the DISA CT shotblast machine.
The shotblast machine is followed by a secondary sorting conveyor. Castings are separated from return scrap; the castings are conveyed to the grinding area and the return scrap is processed in a hydraulic V-jaw breaker in order to reduce the size. After this machine, the return scrap is conveyed directly back to the charging plant.
At JOEST, we always focus on efficiency and reliability when it comes to successfully implementing complex projects. A current example of this is the full modernization of a green sand line at our long-standing partner Fritz Winter – and that in an impressively short time.

In February, JOEST secured an order for the delivery of a specialized 15-meter-long vibrating conveyor for a Serbian producer of sugar products. This machine is an integral part of the production process, conveying freshly centrifuged sugar with a throughput of up to 70 tons per hour at a moisture content of 0,2-0,4% and a product temperature of about 65°C.

At JOEST, we take pride in optimizing our customers’ production with innovative technologies and customized solutions. A recent example is our collaboration with HYDROTEC Technologies AG, an internationally operating company with over 50 years of experience and a clear vision: to continuously improve.
The EuroBLECH 2024 has come to an end, and we would like to extend our heartfelt thanks to everyone who visited us at Hall 7, Stand T24. It was an extremely successful event for the JOEST group, where we had the opportunity to showcase our latest innovations in lifting and tipping systems. Our brand GOESSLING also showcased its advanced solutions in conveying technology.
