  • Core (manufacturing) - Wikipedia

    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. They are most commonly used in sand casting, but are also used in die casting and injection moulding.. For example, cores define multiple passages inside ...

  • Sand Casting For Manufacture - Manufacturing Process

    Cores are made of the highest quality sand and are subject to extreme conditions during the sand casting operation. Cores must be strong and permeable; also, since the metal casting will shrink onto the core, cores must have sufficient collapsibility. Sometimes a reinforcing material will be placed in a sand casting core to enhance strength.

  • Sand Casting Process, Defects, Design

    Another piece of tooling used in sand casting is a core-box. If the casting requires sand cores, the cores are formed in these boxes, which are similar to a die and can be made of wood, plastic, or metal just like the pattern. The core-boxes can also contain multiple cavities to produce several identical cores.

  • An overview of sand core making in casting | Haworth ...

    Using this process, fine AFS graded sand is coated with a resin and blown into a pre-heated core box, ideally made from cast iron, which contains the desired shape. The surface is heated to 210-250°C, depending on the required core. This allows the chemical components in the sand to bond together and form the shape within the core box.
