Hot-chamber die casting,also known as gooseneck machines,rely upon a pool of molten metal to feed the die. At the beginning of the cycle the piston of the machine is retracted,which allows the molten metal to fill the "gooseneck". The pneumatic or hydraulic powered piston then forces this metal out of the gooseneck into the die. The advantages of this system include fast cycle times (approximately 15 cycles a minute) and the convenience of melting the metal in the casting machine. The disadvantages of this system are that it is limited to use with low-melting point metals and that aluminium cannot be used because it picks up some of the iron while in the molten pool. Therefore,hot-chamber machines are primarily used with zinc,tin,and lead based alloys.
