The two main types of casting are metal and non-metal (such as plaster, concrete, or resin). Metal casting involves the heating of a metal into its liquid state and sequentially pouring the liquid into a mold. The mold and metal are allowed to cool until the liquid metal solidifies, at which point the casting is recovered from the mold.

1 天前 For high volume runs of small parts, permanent mold casting (gravity casting) is an option that's both cost effective and produces the quality our customers require. Permanent mold casting is typically used for high-volume production of small, simple metal parts with uniform wall thickness. Non-ferrous metals are typically used in this process ...

The centrifugal force pushes the molten metal toward the boundaries of the mold. There are three types of centrifugal casting processes, namely, (1) true centrifugal, (2) semicentrifugal, and (3) centrifuge casting. True centrifugal casting is used to produce tubular parts such as tubes, pipes, rings, as illustrated in Fig. 7.4.

2022年5月29日 The unit die is a special type of die casting mould. A die caster unit holder keeps the unit dies or customer-owned cavity within the cavity intact. We can have either single or double unitholders. Typical examples of sizes of cavity blocks that the dies hold are 8 x 10, 10 x 12, 12 x 15, and 15 x 18 (all in inches).

Die casting is a type of casting in which molten metal is quickly transferred to a metal mold and the solidification of the metal is in this mold. The transfer of the liquid metal to the mold cavity is carried out by a system where the liquid metal thrust force and the rate of filling the mold can be controlled [6].
