Description

Technical Field

[0002] Castings are metal objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain an object with a certain shape, size and performance. Before casting, the metal material needs to be heated to a molten liquid state, and then injected using an injection device.

[0003] However, after the raw material metal is melted into liquid, there will be a certain amount of slag and the like inside it.
