Abstract (en)

[origin: EP1046444A1] A horizontal chamber die casting process comprises forming a stabilized and homogenized cylindrical melt volume for feeding additional compression of the solidifying cast product in the die. A horizontal chamber die casting process comprises applying a vacuum to the chamber and piston, accelerating the melt befor entry into the die and subjecting the die to pressure before or when the melt reaches the ingate opening. Before acceleration, t melt is formed to a cylindrical shape which is retained until achievement of hydrodynamic stabilization, temperature equalizatio and uniform pressure distribution in the cylindrical material volume and which is fed into the solidifying metal after filling o the die to provide additional compression during solidification of the cast product.
