Reducing Sand Casting Core Defects | EMI White Paper Series ...

The castings and process that require cores will need to be thoroughly defined up front. For example, what kind of finish is the customer looking? Is this a high production job, a periodic runner, or a 1-up prototype casting job? Will venting of the gas from the cores adversely affect your cast product? Is shake out of the cores from the finished casting going to be restrictive in any manner? By defining the economical limits of your decision making matrices, this also will typically lead to you

Core (manufacturing) - Wikipedia

Cores are used for complex injection moldings in the fusible core injection molding process. First, a core is made from a fusible alloy or low melting temperature polymer. It is then placed inside the injection mold's dies and the plastic is shot into the mold. The molding is then removed from the mold with the core still in it.
