After the metal liquid fills the cavity, the time required under the action of pressurization and specific pressure until the internal gate is completely set is called holding time.
The effect of holding time is to crystallize the solidifying liquid metal under pressure, thus obtaining a die casting with dense internal structure.
The length of holding time mainly depends on the type of alloy, the wall thickness of the die casting and the thickness of the inner gate.
The crystallization temperature range of the die casting alloy is large, the average wall thickness of the die casting is large, the thickness of the inner gate is large, the holding time should be longer.Conversely, holding time can be short.
