• Coremaking: Life of a Casting Reliance Foundry

    Cores are made by many of the same methods employed for sand molds. In addition, core blowers and screw feed machines are used. Core blowers force sand into the core box by compressed air at about 100 lb/in 2. They can be used for making all types of small- and medium-sized cores.

  • Cores and Casting of Metals Metallurgy

    Core sands are silica, zircon, Olivine etc. and core binders are core oils, resins, molasses, dextrin etc., are generally used for preparation of core materials. Sand contains more than 5% clay reduces not only permeability but also collapsibility and hence not suitable for core making.

  • What is core shift and why is it detrimental Moore Good Ink

    The term core shift relates to the deviation of a foundry core during the casting process. That is to say, the core moves from its original position, perhaps as a result of inaccuracies in the machining process or the setting of the mold, and leads to alignment problems when the mold is closed.
