In the daily production of aluminum or zinc or copper alloy products, high pressure die casting is used a lot.
Except that, gravity die casting is also widely used, for the big size spare parts.
Referred to as Permanent Mould, GDC - Gravity Die Casting, is a repeatable casting process used for
non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.
The process differs from HPDC - High Pressure Die casting, in that Gravity- rather than high pressure- is
used to fill the mould with the liquid alloy. GDC is suited to medium to high volumes products and typically
parts are of a heavier sections than HPDC, but thinner sections than sand casting.
