The low-pressure casting process proves itself to be predestined for the conversion of exceptionally high quality demands. In low-pressure casting, the furnace is pressurized whereby the molten aluminium is brought into the casting die through the riser tube. The die is filled by slowly climbing, controlled, and above all, constant pressure. The laminar filling process avoids the formation of oxidation, the onset of cold currents and the danger of air inclusions.
The freezing proceeds then from the furthest point of the mould to sprue. During freezing, the furnace pressure is maintained and thus ensures feeding of the castings. Through casting, technical measures and the directed use of the die cooling, the ideal of a vectored freezing is reached.
Low-pressure casting process - controlled mould filling, controlled solidification, high efficiency
With a feeder box this offers a previously unknown flexibility in casting and feeding of parts by means of the low-pressure casting process - independent from the part contour and without additional heat supply. As the number of gating systems and feeders is not limited, several smaller gating can be positioned in different spots at the casting in order to further reduce cycle times.
