It can be more expensive than die casting or sand casting, but per-unit costs decrease with large volumes. Investment casting can produce complicated shapes that would be difficult or impossible with other casting methods. It can also produce products with exceptional surface qualities and low tolerances with minimal surface finishing or machining required
The main disadvantage is the overall cost, especially for short-run productions Some of the reasons for the high cost include specialized equipment,\ costly refractories, and binders, many operations to make a mold, a lot of labor is needed and occasional minute defects. However, the cost is still less than producing the same part by machining from bar stock; for example, gun manufacturing has moved to investment casting to lower costs of producing pistols Investment casting is used with almost any castable metal. However, aluminum alloys, copper alloys, and steel are the most common. In industrial use, the size limits are 3 g (0.1 oz) to several hundred kilograms. The cross-sectional limits are 0.6 mm (0.024 in) to 75 mm (3.0 in).
