Web1. Introduction. In any casting process, when an alloy is poured into a mold, it starts to shrink or contract in volume as it cools down to liquidus temperature, and subsequently solidifies. These two stages of volumetric … WebAccordingly, there are two types of gating systems in casting process: pressurised and non-pressurised, or free flowing like a sewer system. Pressurised Gating System. The …
WebThe gating/feeding system initially governs the mold filling operation and guides the molten metal as it flows into the mold filing cavity, later while solidification it guides the feeding liquid into this cavity as compensation for the first two stages of alloy contraction. WebMar 31, 2024 · The gating system controls the flow of molten material into the mold cavity and affects the part’s quality and consistency. The design of the gating system must be carefully considered to ensure that the molten material is distributed evenly throughout the mold and that the part’s surface finish is of high quality.
