It is a machine designed to form sand cores using the “Hot Box” method. It is possible to convert the machine to the “Cold Box” and “Shell” method when requested.
The machine movements are hydraulically driven, so the machine has an extremely high core box closing force. It has a capacity of 5 litres, so it can form medium/large cores or small cores with multiple cavities in the core box.
The machine process is managed by a PLC control unit provided with a graphic display. The machine slides the arm assembly towards the operator to facilitate the installation of core boxes. The core boxes are heated by electrical elements, the temperature is controlled by two independent thermocouples with regulators. The machine can also be supplied with an automatic sand feeding system.
