Patent number: 4763720Abstract: For the fabrication of a disintegratable sand core, refractory particles such as silica sand are mixed with two binders, one consisting of an inorganic substance such as a silicate and the other consisting of a starch, and, preferably, with water. The two binders function to cancel the disadvantages arising from the use of only either. The mixture is introduced into a core box molded essentially of materials pervious to microwave energy. Exposed to microwave energy through the core box, the mixture hardens in the shape of the core box cavity. For the production of cores having greater surface stability at room temperature, the starch and water are first mixed together into a paste, and this paste is added to the refractory particles together with the inorganic binder, thereby assuring uniform dispersion of the starch throughout the mixture.Type: GrantFiled: August 17, 1987Date of Patent: August 16, 1988Assignee: Kabushiki Kaisha Komatsu SeisakushoInventors: Toshio Sakamoto, Kanichi Sato, Yoshiyuki Takemura
