What is a core blower?
[′kȯr ‚blō·ər] (metallurgy) A machine using compressed air to blow and pack sand into a core box.
What is a core box casting?
A core is a preformed, bonded, sand insert placed into the mold to shape the interior of a casting or a part of the casting that cannot be shaped by the pattern. Cores are frequently used to create hollow sections or cavities in a casting.
What is core box in foundry?
Any kind of hollowness in form of holes and recesses in castings is obtained by the use of cores. Cores are made by means of core boxes comprising of either single or in two parts. Core boxes are generally made of wood or metal and are of several types.
What is a cold box casting?
Process for the production of cores in which, in principle, cold, i.e. not heated or hot, core boxes are used.
What is the use of core box?
A core box is the tooling used to create the core. High-quality cores are essential to the iron casting process.
What are the types of core box?
The main types of core box are half core box, dump core box, split core box, strickle core box, right and left hand core box and loose piece core box. This is the most common type of core box. The two identical halves of a symmetrical core prepared in the half core box are shown in Fig. 10.17.
What is the function of a core box?
The wooden, metal, or cardboard box divided into narrow parallel sections, used to store the cores at the surface as they are extracted from a core barrel or corer. ii. The box in which the core, or mass of sand producing any hollow part of a casting, is made.
What is the purpose of core boxes?
Cores are compact mass of core sand that when placed in mould cavity at required location with proper alignment does not allow the molten metal to occupy space for solidification in that portion and hence help to produce hollowness in the casting.
What is cold box binders?
What is the binder for cold box? It is a gas hardening binder with silica sand and other aggregate coated with phenol resins and polyisocyanate. When exposed to gaseous basic catalyst, it instantly exhibits the urethanation reaction to generate bonds between sand particles.

What is core and core box?
What is core venting and function of core?
The core enclosed by the molten metal develops gasses (see Core gasses). In the best case, with sufficient permeability to gas of the molding material they can escape from the core to the ambience through the core prints. However, in many cases an additional core vent is required.
What are different types of core boxes?
The main types of core box are half core box, dump core box, split core box, strickle core box, right and left hand core box and loose piece core box. This is the most common type of core box.
