Abstract: First, a nozzle insertion process in which a nozzle is inserted into a water cooling hole having a small diameter which is provided in a back of a mold is performed. Then, an injection process in which a mixed flow of air having a pressure ranging from 0.1 MPa to 1.0 MPa with an injection particle is jetted from a leading end of a nozzle to a distal portion of the water cooling hole. As a result, a shot peening process is performed on the distal portion of the water cooling hole.

Abstract: By mixing, stirring and kneading, with water glass (11) as a binder, sand (7), a surfactant (9), and water (10), foamed sand (S) is generated. The foamed sand (S) is packed in a cavity of a metallic mold and solidified to form a sand mold. By using the sand mold, aluminum is cast. By using water glass that is an inorganic binder, during casting, harmful gas and odor are not generated. Further, when a molar ratio n of water glass (Na20 nSiO2 mH2O) is adjusted in the range of 0.65 to 1.30, a quantity of water (H2O) generated by heating water glass with a high temperature melt during casting can be suppressed. Thereby, hydrogen gas (H2) according to a reaction between water (H2O) and aluminum (Al) can be suppressed from being generated and casting quality can be improved.

Abstract: A system for shot peening that includes an enclosure in which are provided a workpiece W to be shot peened and a nozzle for projecting the shot particles. A memory stores data for maximizing the anticipated shot-peening intensity at the workpiece based on the predetermined conditions of the shot peening. Then a calculating circuitry determines the conditions of the shot peening to be carried out in the system to maximize an anticipated shot-peening intensity at the workpiece based on the stored data from the memory and the selected type of the shot-peening process to be applied to the workpiece before the shot particles have been actually projected. The nozzle is then actuated under the determined conditions such that it projects the shot particles and directs them onto the workpiece. The shot-peening intensity of the actually projected shot particles at the workpiece is measured by a measuring device. Then a calibration circuitry controls the mass-flow rate of the shot particles and the pressure or the flow rate of the compressed air to maximize the measured shot-peening intensity based on the stored data such that the nozzle projects the shot particles under the corrected and controlled conditions.

Abstract: A method for compacting molding sand in a mold space defined by a pattern plate, which is fixed in a horizontal position when the molding sand is compacted, a leveling frame disposed for vertical sliding movement around the outer periphery of the pattern plate, a frame member disposed for vertical movement above the leveling frame, and a filling frame disposed for vertical movement above the frame member. The method comprises the steps of feeding molding sand into the mold space, primarily compacting the molding sand in the mold space from above by compacting means while at least the leveling frame is being set so that it cannot be lowered, and secondarily compacting the molding sand in the mold space from above by the compacting means while the leveling frame, the frame member, and the filling frame are set so that these elements can be lowered.
