Low and High Pressure Die Casting Mould

Low and High Pressure Die Casting Mould 

HPDC is a process in which molten metal is forced under pressure into a securely locked metal die cavity, where it is held by a powerful press until the metal solidifies. LPDC is a process in which  a ceramic tube is connected to a steel die above and extends into a furnace of molten metal below once the casting has solidified the air pressure is reduced allowing the rest of the metal still in liquid form in the tube to recede back into the furnace.
