Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue.

36. The optimum pouring time for a casting depends on several factors. One important factor among them is [1991] (a) location of riser (b) porosity of sand mold (c) fluidity of casting metal (d) area of the pouring basin Solution: (c) 37. Ceramic slurry is used in making the molds for [1991] (a) investment casting (b) die casting (c) shell mold casting (d) centrifugal casting Solution: (a) In ...

Centrifugal Casting: A process of filling molds by 1) pouring metal into a sand or permanent mold that is revolving about either its horizontal or its vertical axis; or 2) pouring metal into a mold that is subsequently revolved before solidification of the metal is complete.

The Casting Channel acts like the fluid pipes from BuildCraft or Fluiducts from Thermal Expansion.When placed directly below a faucet connected to a Smeltery drain, it will transport the liquid towards another fluid storage block (eg. Tank). Note: Casting channels will not store fluids, meaning that, unlike BC pipes, they need to be connected to a tank etc.

The necessity to stop the pouring of liquid metals is becoming urgent. Pouring is the main source of entrained bifilms.
