Like high-pressure die casting from zinc investment casting manufacturer, to a fixed and moving machine plate, here also the parts of the die are attached but the machine is vertically aligned. Beneath the fixed plate the furnace for the molten metal is placed.
To the furnace applying pressure of up to max is reliable. The molten metal is pushed by 1 bar (usually aluminum and magnesium) into the die chamber up through an intake port. Sand moulds can be used although it is usually a permanent mould. Against gravity, the molten metal’s upward movement act.
This naturally ensures solidification that is also possible from top to bottom.
High-pressure die casting
Because of the high pressure used in aluminum high pressure die casting when pouring – up to 1,200 bar – the bolts must have a high locking force that holds the two halves of the die together.
Cold-chamber die casting machines are mainly used for aluminum alloys because these have a relatively high melting point. Here, at the exterior side of melt, the zinc investment casting china assembly is placed. To a shot chamber the molten metal is input, from where the metal is driven into the die by a piston. The two parts of the die are opened once the metal has cooled and solidified and by ejector pins the casting is automatically ejected from the die.
