Abstract: A three-dimensionally laminated object modeling apparatus includes a cylinder configured to store a molten resin, a discharging nozzle that is communicated with the cylinder, and a piston configured to discharge the molten resin from the discharging nozzle by moving in a direction of approaching the discharging nozzle and by pressurizing the molten resin in the cylinder, and models a three-dimensionally modeled object by laminating a resin bead that is the molten resin discharged from the discharging nozzle on a table. It includes a drive device configured to relatively move the discharging nozzle with respect to the table and at least one processor configured to acquire a movement speed of the discharging nozzle and control movement of the piston based on the movement speed of the discharging nozzle.

Abstract: An injection molding machine includes a cylinder that accommodates a molten resin, a discharging nozzle, a piston that discharges the molten resin from the discharging nozzle, and one or more processors configured to execute the following functions. The functions include calculating a target pressure at which a flow rate of the molten resin discharged from the discharging nozzle becomes an indicated flow rate, controlling a pressure of the molten resin in the cylinder such that the pressure becomes the target pressure, acquiring a temperature of the molten resin in the cylinder, and acquiring a pseudo-plastic viscosity corresponding to the temperature of the molten resin. The target pressure is calculated based on the indicated flow rate, the temperature of the molten resin, the pseudo-plastic viscosity, and the size of the discharging nozzle.

Abstract: An injection molding machine capable of changing the position of the supply hole of the resin material in a cylinder as appropriate is provided. An injection molding machine according to one aspect of the present disclosure includes: a supply hole through which a resin material is supplied to an inside of a cylinder, the supply hole being formed in a side wall part of the cylinder; and a closing part that, when a torpedo piston moves to a side of an other end part of the cylinder in order to plasticize the resin material, moves together with the torpedo piston and closes the supply hole.

Abstract: An injection molding machine that contributes to improving the quality of a workpiece is provided. An injection molding machine configured to causes torpedo pistons to be slid in one way to thereby plasticize a resin material supplied to a first space of a cylinder, and causes a molten resin to flow into a second space of the cylinder and causes the torpedo pistons to be slid in the other way to thereby inject the molten resin. The injection molding machine includes pressurizing pistons inserted into the torpedo pistons so that the pressurizing pistons can be slid in such a way that an amount of protrusion of the cylinder into the second space of the cylinder with respect to the torpedo pistons is changed, and energizing means for energizing the pressurizing pistons toward the second space of the cylinder.

Abstract: A wear-resistant member production method includes: forming a clad layer by moving, relative to a substrate while feeding cladding powder onto the substrate and melting it using a local heating device; and cutting the clad layer. The cladding powder includes matrix powder containing a copper-based alloy, and hard powder including, as a hard phase, a silicide containing one or more elements selected from Cr, Fe, Co, Ni, and Cu, and one or more elements selected from Mo, W, and Nb. The hard powder includes first hard powder and second hard powder. The second hard powder is fed, separately from the first hard powder, to a melt pool formed by melting the first hard powder and the matrix powder, such that at least part of the second hard powder remains unmelted within the clad layer.
