Difference between Sand casting, Die casting and Investment casting
Sand casting, Die casting, and Investment casting are widely used casting processes worldwide to make metal parts for the consumer, automobile, medical and aerospace industries.
Casting processes
Metal casting is a manufacturing process in which molten metal is poured into a mould, which then solidifies to form a desired shape.
Metal Casting
Molten metal is poured into a desired geometrical shape mould cavity and cooled to produce a solidified object in metal casting.
Sand Casting
In sand casting, molten metal is poured into an expendable sand mould cavity where it solidifies to form the cavity shape part
Investment Casting
In investment casting, a wax pattern is coated with a refractory material to make a mould, which is then melted away before pouring molten metal into the cavity to solidify.
Centrifugal casting
Centrifugal casting uses inertial forces induced by rotation to distribute molten metal into mould cavities to cast cylindrical
Die casting
In Die casting, molten metal is forced into the mould cavity called “die” at pressure, where it solidifies into a metal cast.
