high pressure die casting for Reliable and cheap in Maldives

Casting Speed - an overview ScienceDirect Topics

The high heat capacity and low thermal conductivity of steel combined with the high casting speeds in thin slab casting (5 to 6 m/min), make it a reasonable assumption that the heat transferred by conduction in the axial (z) direction is negligible compared to the heat transferred by the bulk motion of the strand. Furthermore, in thin slab casting the thickness of the slab is very small ...

HPDC vs LPDC Die Casting cameldie

HPDC vs LPDC Die Casting. High-pressure casting is a process in which molten metal is poured into a pressure chamber so that the molten metal fills the mold cavity at high speed and then solidifies under high pressure to form a casting. The flow speed during filling can reach 30-80mm/s, and the time for filling the cavity is extremely short.
