A core-type core is a magnetic circuit equivalent to an electric series circuit, whereas a shell-type core is equivalent to an electric parallel circuit. This is better answered with a diagram, so I suggest that you do a search on the internet.
Core: A sand or metal insert in a mold to shape the interior of the casting or that part of the casting that cannot be shaped by the mold pattern. The portion of the cast which forms the internal shape
Die Casting : Complete Handbook For All Metal Die Casting (14K Free PDF Download) this refers to the extent a mold core is tapered. This reduces chances of shrinkage and makes it easy to remove the cast part. Factors that determine the type of draft include: type of metal alloy, wall thickness and the shape of the die. The parting line; this is the line that connect various sections of the
below the casting surface and morphology. It follows therefore that the cause of such It follows therefore that the cause of such defects in a real casting can be deduced from a careful examination.
Core print is the region added to the pattern, core, or mold that is used to locate and support the core within the mold. A riser is an extra void created in the mold to contain excessive molten material. The purpose of this is feed the molten metal to the mold cavity as the molten metal solidifies and shrinks, and thereby prevents voids in the main casting.
Centrifugal casting process is a subject which is emerging in the present foundries. The reason for this seminar being chosen is to get theoretical knowledge of centrifugal casting process and machines.
• The essential feature of centrifugal casting is the wheel ro‐tates around its hub core, the mold cavity is filled from rim‐to‐hub‐not from bottom‐to‐top as is the case of common gravity pouring. This action promotes the direction of solidification from rim‐to‐hub and provides the required feeding by using only one central reservoir. Pouring and feeding on the center hub
• Types of cores – Unbalanced core – Balanced core – Cover core – Vertical core – Drop core . Core prints • Purpose – Securely hold the core in position relative to mould cavity and the core print is a part of core Core Core print Chaplet Mould .
A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. [1]
A casting defect is an undesired irregularity in a metal casting process. Some defects can be tolerated while others can be repaired, otherwise they must be eliminated.

Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting , which is ejected or broken out of the mold to complete the process.
Dry type transformer or more commonly known as Cast Resin transformer is a transformer of which the magnetic circuit and windings are not immersed in insulating oil but used air as insulating agent.
The core prints are provided as a projection at the end of core. Properties of cores : Permeability – Vents are provided in core to escape the gases generated during casting.
The core stretches across the casting cavity and is fitted into core print sockets that extend over the edge of the cavity. The fit into the core print will allow for the stabilization of the core, which will in turn, allow for creation the passage desired for the casting.

• The essential feature of centrifugal casting is the wheel ro‐tates around its hub core, the mold cavity is filled from rim‐to‐hub‐not from bottom‐to‐top as is the case of common gravity pouring. This action promotes the direction of solidification from rim‐to‐hub and provides the required feeding by using only one central reservoir. Pouring and feeding on the center hub
Dry type transformer or more commonly known as Cast Resin transformer is a transformer of which the magnetic circuit and windings are not immersed in insulating oil but used air as insulating agent.
A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. [1]
