The new AL 28-18-18 FSC extends the portfolio of the Kurtz low-pressure casting machines with more clamping area and hydraulic power. It relies on proven Kurtz low-pressure die casting technology in order to achieve greater benefits for users through newly optimized assemblies and components.
Thanks to the innovative trapezoidal arrangement of the guide columns, tool formats with maximum 2,800 mm width and 2,000 mm depth can be clamped in place. The optional hydraulic clamping system allows a faster die setup without aids. A stroke of 1,800 mm with 2,600 mm clear width at the closing unit permit simple removal of the components by means of the added removal unit and also provides excellent preconditions for robot automation. An optional tilting moving plate allows best accessibility for coating and cleaning. Milestone and highlight is without doubt the die gap detection function, which prevents aluminium leaking if the casting die is not completely closed and avoids production downtime.
The completely new hydraulic system of the AL 28-18-18 FSC makes even faster machine movements possible with higher forces. With this system, greater clamping forces are achieved during casting, the part ejecting forces can be up to 100 tonnes. The low-noise hydraulic pumps can be switched on individually in order to achieve the necessary pressures and flows – with increased energy efficiency. Up to eight additional ejector cylinders which can be positioned flexibly on the movable clamping plate support the central ejector cylinder with up to twelve additional guiding columns.
The cooling system of the AL 28-18-18 FSC has 96 mixing (air/water) circuits available which can be connected to the die through smooth multi-couplings. An extension to 128 mixing circuits is possible. In order to guarantee high availability of the Kurtz casting machine AL 28-18-18 FSC, the “condition monitoring” option allows the condition of the casting machine to be monitored at all times, enabling to detect possible stoppages or downtimes early and any resulting maintenance work to be planned.
