-Close dimensional tolerance.
-Complex shape, fine detail, intricate core sections and thin wall are possible.
-Smooth finish (degree finish) between 64 to 125 RMS.
-Best suited for low volume production rates.
-Ferrous and non-ferrous metals may be cast.
-Costs are higher than sand, gravity mold castings.
-Use when complexity precludes use of sand or permanent mold castings.
-The process cost is justified through savings in machining or brazing.
