STEP 0: Pre-Calculation Summary

Formula Used

Buoyant Force = Empirical constant*Core Print Area
F_buoyant = c*A
This formula uses 3 Variables

Variables Used

Buoyant Force - (Measured in Newton) - Buoyant Force is the upward force exerted by any fluid upon a body placed in it.
Empirical constant - (Measured in Pascal) - Empirical constant is the constant used in an empirical relation. It may have some units.
Core Print Area - (Measured in Square Meter) - Core print area is the area of that part of the mould which supports the weight of core used in casting.

STEP 1: Convert Input(s) to Base Unit

Empirical constant: 350 Newton per Square Millimeter --> 350000000 Pascal (Check conversion here)
Core Print Area: 4E-06 Square Meter --> 4E-06 Square Meter No Conversion Required

< 13 Cores - Core Prints and Chaplets Calculators

Buoyant Force on Vertical Cores

Go Buoyant Force = (pi/4*(Diameter of Core Print^2-Diameter of Cylinder^2)*Height of Core Print*Density of Metal-Volume of the Core*Density of Core)*[g]

Buoyant Force on Cylindrical Cores Placed Horizontally

Go Buoyant Force = pi/4*Diameter of Cylinder^2*[g]*Cylinder Height*(Density of Metal-Density of Core)

Metallostatic Forces Acting on Moulding Flasks

Go Metallostatic Force = [g]*Density of Metal*Projected Area in Parting plane*Head of Molten Metal

Density of Core Material

Go Density of Core = Density of Metal-Buoyant Force/(Volume of the Core*[g])

Volume of Core

Go Volume of the Core = Buoyant Force/(9.81*(Density of Metal-Density of Core))

Density of Molten Metal

Go Density of Metal = Buoyant Force/(Volume of the Core*9.81)+Density of Core

Buoyant Force on Cores

Go Buoyant Force = 9.81*Volume of the Core*(Density of Metal-Density of Core)

Chaplet Area

Go Chaplet Area = 29*(Buoyant Force-Empirical constant*Core Print Area)

Unsupported Load for Cores

Go Unsupported Load = Buoyant Force-Empirical constant*Core Print Area

Buoyant Force on Cores from Chaplet Area

Go Buoyant Force = Chaplet Area/29+Empirical constant*Core Print Area

Empirical Relation for Max. Permissible Buoyancy Force on given Core Print Area

Go Buoyant Force = Empirical constant*Core Print Area

Empirical Relation for Minimum Core Print Area

Go Core Print Area = Buoyant Force/Empirical constant

Chaplet Area from Unsupported Load

Go Chaplet Area = 29*Unsupported Load

Empirical Relation for Max. Permissible Buoyancy Force on given Core Print Area Formula

Buoyant Force = Empirical constant*Core Print Area
F_buoyant = c*A

What to consider while designing core prints for molding?

Core print area is the area of that part of the mould which supports the weight of core used in casting. The design of core prints is such as to take care of the weight of the core before pouring and the upward metallostatic pressure of the molten metal after pouring. The core prints should also ensure that the core is not shifted during the entry of the metal into the mould cavity.
