The image represents rated static head (in top gating). To calculate rated static head (int top gating), one essential parameter is needed and the parameter is Height of the Sprue from its Top to the Point of Metal Entry into the Mould Cavity (H).
The formula for calculating rated static head (in top gating).
Hs = H
Where the following applies:
Hs = Rated Static Head (in top Gating)
H = Height of the Sprue from its Top to the Point of Metal Entry into the Mould Cavity
Let’s solve an example;
Find the rated static head (in top gating) when the height of the sprue from its top to the point of metal entry into the mould cavity is 10.
This implies that;
H = Height of the Sprue from its Top to the Point of Metal Entry into the Mould Cavity = 10
So, Hs = H
Hs = 10
Therefore, the rated static head (in top gating) is 10.
