Magnesium alloy casting techniques are differ from hot chamber die casting and cold chamber die casting machine. The typical technique of Mg alloy casted by hot chamber die casting machine is as following:

1) The casting temperature of Mg alloy liquid is usually controlled between 620℃ and 640℃. But in real large scale production, it should be adjusted according to production and goods technical requirements.

2) The good mould temperature control can ensure Mg alloy liquid have better flowing and filling condition.
   The mould temperature is usually controlled btween 230℃ and 280℃. It can also be adjusted by goods specificaation and production period.

3) Injection force of the hot chamber die casting machine should be controlled betweeen 16MPa and 25MPa,

4) Because Mg alloy has the characteristics of big dynamic viscosity and short freezing time.  The hot chamber die casting machine must meet following requirements: quick injection time, short filling time. The common injection speed should be bigger than 6m/s.   http://www.die-casting-machine.com/
