20160101462 | PRECISION-CASTING CORE, PRECISION-CASTING CORE MANUFACTURING METHOD, AND PRECISION-CASTING MOLD - A coating layer including solely silicon alkoxide or mixed alkoxide of silicon alkoxide and aluminum alkoxide is formed on a surface of a sintered precision-casting core body mainly including silica particles so as to seal holes formed in the surface. As a result, it is possible to prevent the breakage of the core during casting. | 04-14-2016 |
20160114384 | PRECISION-CASTING CORE, PRECISION-CASTING CORE MANUFACTURING METHOD, AND PRECISION-CASTING MOLD - A precision-casting core body is formed by mixing and sintering silica particles and silica fume. The resistance of the mixture of silica fume decreases during heating injection molding, and hence the fluidity is improved by the addition of silica fume. As a result, since the fluidity is improved, it is possible to decrease an injection molding pressure when a core is manufactured. Further, the mixture can be applied to a thin compact and a complex compact with improved fluidity. | 04-28-2016 |
