Hb = h-c/2
This formula uses 3 Variables
Variables Used
Effective Metal Head For Bottom Gate - (Measured in Meter) - Effective Metal Head For Bottom Gate is the height of molten metal above the bottom gate in a casting system, ensuring sufficient pressure to fill the mold cavity effectively.
Height of Sprue - (Measured in Meter) - Height of Sprue is the height that is specified of sprue passage only, used in mould during casting.
Total Height of Mould Cavity - (Measured in Meter) - Total Height of Mould Cavity is the vertical dimension of the cavity within the casting mold, encompassing the entire depth from the top to the bottom of the mold.
STEP 1: Convert Input(s) to Base Unit
Height of Sprue: 9 Centimeter --> 0.09 Meter (Check conversion ​here)
Total Height of Mould Cavity: 4.5 Centimeter --> 0.045 Meter (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Hb = h-c/2 --> 0.09-0.045/2
Evaluating ... ...
Hb = 0.0675

What is Effective metal head?

Effective metal head is the actual head of metal available at the gate of mould cavity. It is the head which will get converted to velocity of molten metal available for filling the mould cavity. It is usually different for many different gating systems. For top gating system it is same as sprue height.

How to Calculate Effective Metal Head for Bottom Gate?

Effective Metal Head for Bottom Gate calculator uses Effective Metal Head For Bottom Gate = Height of Sprue-Total Height of Mould Cavity/2 to calculate the Effective Metal Head For Bottom Gate, Effective Metal Head for Bottom Gate is the vertical distance between the surface of the molten metal in the pouring basin or sprue and the gate through which the metal enters the mold cavity and calculated as the difference in height between the pouring basin or sprue and the gate, taking into account any losses due to friction and turbulence in the gating system. Effective Metal Head For Bottom Gate is denoted by Hb symbol.

How to calculate Effective Metal Head for Bottom Gate using this online calculator? To use this online calculator for Effective Metal Head for Bottom Gate, enter Height of Sprue (h) & Total Height of Mould Cavity (c) and hit the calculate button. Here is how the Effective Metal Head for Bottom Gate calculation can be explained with given input values -> 675 = 0.09-0.045/2.

FAQ

What is Effective Metal Head for Bottom Gate?
