Gating and risering system

A riser is categorized based on three criteria: where it is located, whether it is open to the atmosphere, and how it is filled. If the riser is located on the casting then it is known as a top riser, but if it is located next to the casting it is known as a side riser. Top risers are advantageous because they take up less space in the flask than a side riser, plus they have a shorter feeding distance. If the ris… WebJan 1, 2024 · Dimensions of the gating system need to be well calculated according to the product geometry. Each production part has different dimensions and geometrical …
