Design and fabrication of the device to demonsrate the fluiding of molten metal and alloys / Ahmad Tajuddin Kassim and Ismail Abdul Rahaman

Sand casting offers the widest scope of all the casting processes as far as size and complexity of shape and range of alloy is corcerned. When only small member of casting are required it is normally the only reasonably economical method of production. In weight, sand casting range from less than an once up to more than 100 tons and is size from an inch or less up to 70 feet or more in length. Nearly all. alloys can be sand cast, including relatively hot short materials. It is very flexible process in that risers and runners, can be located almost any where on a casting because of the ease of working of the moulding medium, whereas in die casting because runners and risers must be located on die parting lines or extraction is impossible. For very large casting, moulding in sand is the only practicable means of production. Good internal soundness can be obtained by this method.
