Abstract:
1. An injection machine comprising: a heating barrel which heats a powder material, a binder, and a resin material into a molten resin; a screw mounted in the heating barrel to mix the resin material; a motor which drives the screw in rotation; a through-hole disposed on a side surface of the heating barrel; a pipe in which a solvent for adjusting a viscosity of the resin material is conducted, the pipe being connected to the through-hole; a filter disposed in the through-hole to prevent the resin material from leaking to the pipe; a valve disposed midway on a pipeline of the pipe; a reservoir disposed on an end of the pipeline of the pipe; a load-detecting part which detects a load value of the motor; a controlling part which sets a reference value with respect to a load of the motor; and a driving part which compares the detected load value with the reference value to drive the valve to carry out either one of supply or discharge of the solvent.
