Sand Casting

Sand casting is a cast part produced by forming a mold with the help of a model or pattern pressed into a sand mixture and then removed. After the molten liquid aluminium is poured into the cavity in the mold. The mold is then cooled until the aluminium has solidified. Finally, the casting is separated from the sand mold.

  Gravity Die Casting

Permanent mold casting is metal casting process that employs reusable molds or permanent molds, usually made from metal. The most common process uses gravity to fill the mold. The gravity process begins by preheating the mold to 150-200 C (300-400 F). The mold cavity is then coated with a refractory material or a mold wash, which prevents the casting from sticking to the mold and prolongs the mold life. Any sand or metal cores are then installed and the mold is clamped shut. Molten metal is then poured into the mold. Soon after solidification the mold is opended and the casting removed to reduce chances of hot tears.
