· Mechanical property test;

· Hardness test: To ensure the hardness meet customers’ needs;

· Grain fineness test;

Concentration Melting Inspection

· Temperature test: In order to be keep the good fluidity while die casting, the temperature of the molten aluminum and its alloy shall be real time monitored and can be transferred only when the temperature reaches above to 680.

The Processing Monitoring Of Aluminum Die Casting

· Moulds temperature control: To control die casting quality through monitoring moulds temperature by usinginfrared thermometer.

· Die casting processing inspection: to ensure the appearance and inside structure of aluminum die castings qualified

· Mould discharging agent test: the mould discharging agent plays very important roles to the quality of die castings. It will be spotted by discharging agent when it too much or stuck in the mould once it too little.
