There are four main types of permanent mold casting: gravity, slush, low-pressure, and vacuum. The gravity process begins by preheating the mold to 150–200 °C (300–400 °F). to ease the flow and reduce thermal damage to the casting. The mold cavity is then coated with a refractory material or a mold wash, which prevents the casti
خبير الاتصالNon-expendable mold casting differs from expendable processes in that the mold need not be reformed after each production cycle. This technique includes at least four different methods: permanent, die, centrifugal, and continuous casting. This form of casting also results in improved repeatability in parts produced and delivers near net shape results.

خبير الاتصالPermanent 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.
خبير الاتصالPermanent mold casting (PMC) is the process of transferring molten metal to a metal mold by the gravity assistance and ensuring that the metal solidifies in this mold. If cores made of sand or plaster used in the PMC, method is called as semi-PMC [6,8].PMC is especially practical for the high-volume casting production.
