Aluminum Die Casting Draught Fan FEATURES:

Castings are used virtually every where. The transport sector and heavy equipment is the predominant consumer (for farming, construction and mining) taking up over 50% of castings produced.

A sector wise casting consumption is given below which highlights the importance of casting in any industrial set up.

 â€¢  Heavy equipment like machine leads, ship`s propeller, etc. can be thrown easily in the required size rather than fabricating them by joining several small pieces.
 â€¢  Casting is best suited for composite components requiring different properties in various direction. These are made by incorporating preferable inserts in a casting. For example, aluminum conductors into slots in iron armature for electric motors, wear resistant skins onto shock resistant components.
