When die casting machine tonnage is not confirmed, the larger tonnage of the die casting machine, the bigger size of the mould can be installed, the more die cavities of a mould can be made.
When die casting machine tonnage is confirmed, the die cavity quantity depends on the size of the mold and flow channel should not be too large or too long, if the coordination is not good, there may be several mold holes in each mold, so that it is meaningless to make a mold with multiple cavities. Another aspect for die casting mould cavities, we should consider the quantity of the alloy die casting parts we need to produce, if small quantity, it is not economy to make die casting mould with multiple cavities. Normally die casting parts’ structure is complex, its mould will do one cavity to ensure die casting quality.
