We have 4 pressure die casting cells in the business, 2 Buhler machines for the production of castings up to 4.5kg, 1 Frech DAK unit for the production of castings up to 10.5kg or for use with dies on bolster plates and finally a larger Buhler with the capacity for castings up to 25kg.
Die casting is a metal casting process that is characterized by forcing molten metal under high pressure pistons into a mould cavity. The mould cavity is created using two hardened tool steel dies which have been machined into shape and work similarly to an injection mould during the process.
Robotic arms are used to ladle in the molten metal as well as to remove the casting once finished and to spray the moulds in preparation for the next “shot”. Other automated processes include clipping tools used to remove the casting from its feeder system – this reduces the amount of manual finishing required to a minimum if any at all.
High pressure die casting is predominantly used high volume cast parts, where consistent accuracy and high tolerances are required. The set up costs are more than that of sand casting and gravity die casting however this is countered by a vastly reduced unit cost.
