What to consider while designing cores for molding?

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.

FAQ

What is Buoyant force on cores?
The Buoyant force on cores can be calculated as the difference in the weight of the liquid metal to that of the core material of the same volume as that of the exposed core and is represented as Fb=9.81*V*(δ-d) or Buoyant Force=9.81*Volume of the core*(Density of metal-Density of core). Volume of the core is the amount of space occupied by the core, Density of metal is the mass per unit volume of the given metal and Density of core is the given density of core material.
