Casting Process - MRT Castings Ltd

Gravity Die Casting. Gravity die casting is produced by pouring molten metal into permanent cast-iron moulds. This process produces chill castings. The process has a higher casting rate than sand casting, but the metal moulds are higher cost than sand patterns. Advantages include the possibility of low gas porosity, and fine grain sizes can be ...

Permanent mold casting - Wikipedia

Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal.The most common process uses gravity to fill the mold, however gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces hollow castings.Common casting metals are aluminium, magnesium, and copper alloys.

Gravity Vs Low Pressure Cast at Tire Rack

Low Pressure Casting Low pressure casting uses positive pressure to move the molten aluminum into the mold quicker and achieve a finished product that has improved mechanical properties (more density) over a gravity cast wheel. There is a slightly higher production cost over gravity casting, but low.

Permanent Mold Casting Process - Batesville Products (800 ...

The basic difference between permanent mold and die-casting is that permanent mold is a gravity feed process whereas die-casting uses pressurized injection. Gravity feed yields a denser casting. Metal molds (or dies) usually are made of high-alloy iron or steel and may have a production life of 120,000 castings or more.
