Method of core removal from molded products |
摘要 |
A method of removing a core from a molded product in which the core is formed of a particulate inert material, such as sand, bound together by a cured water soluble binder. The binder is cured by heat. The core and molded product are exposed to water, preferably heated water in a bath or steam, after the product has been molded to rapidly disintegrate the core and remove it from the molded product.
