Expendable mold casting

Investment casting

Investment casting is one of the oldest manufacturing processes, dating back thousands of years, in which molten metal is poured into an expendable ceramic mold. The mold is formed by using a wax pattern - a disposable piece in the shape of the desired part.

CO₂ process casting.

CO₂ Casting is a kind of sand casting process. In this process the sand molding mixture is hardened by blowing gas over the mold. This process is favoured by metal casters because a lot of cost cutting can be done. In addition, one can be sure of getting dimensionally accurate castings with fine surface finish. But, this process is not economical than green sand casting process.

Shell Mold Casing

Shell mold casting is a metal casting process similar to sand casting, in that molten metal is poured into an expendable mold. However, in shell mold casting, the mold is a thin-walledshell created from applying a sand-resin mixture around a pattern.

Non-expendable mold casting

Squeeze Casting

Squeeze casting as liquid-metal forging, is a process by which molten metal solidifies under pressure within closed dies positioned between the plates of a hydraulic press.

Low Pressure Casting

Low-pressure permanent mold (LPPM) casting uses a gas at low pressure, usually between 20 to 100 kPa to push the molten metal into the mold cavity. The pressure is applied to the top of the pool of liquid, which forces the molten metal up a refractory pouring tube and finally into the bottom of the mold. The pouring tube extends to the bottom of the ladle so that the material being pushed into the mold is exceptionally clean. No risers are required because the applied pressure forces molten metal in to compensate for shrinkage.
