1.5 Gravity die casting<br />
1.5.1 Characteristics of process<br />
Gravity die casting is one of the standard processes for the manufacture of high-integrity<br />
automotive castings. It represents proven and absolute precision technology for the<br />
production of large batch quantities. This process is used in carousel casting units or in<br />
shuttle technique particularly for the manufacture of engine castings.<br />
Optimum heat dissipation from the solidifying casting through the die leads to short<br />
solidification times. This results in castings which have good mechanical properties,<br />
especially after an additional heat treatment.<br />

In addition to producing ever more complicated cylinder heads for petrol and diesel engines,<br />
gravity die casting is also used for the manufacture of diesel engine blocks with cast-in grey<br />
iron liners.<br />
