1.3.3 DISAmatic casting<br />
Automated green sand casting: DISAmatic, AGSC<br />
Automated green sand casting offers a reasonable alternative to conventional die casting<br />
processes (high pressure / low pressure / vacuum-assisted or not). This holds for middle and<br />
high volume series, especially for automotive applications.<br />
<strong>Manufacturing</strong> in high pressure die casting is limited by wall-thickness and design. I.e.<br />
producing a complicated inner structure by using lost cores is still not economically feasible in<br />
this process. Low pressure die casting's productivity is limited by solidification time, leading to<br />
cycle times of typically several minutes. Automated green sand casting has no such limits.<br />
The original DISAmatic process was advanced by Alcoa for manufacturing of high-quality<br />
automotive castings. Alcoa's variant green sand casting is AGSC (Alcoa Green Sand<br />
<strong>Casting</strong>).<br />
