抑えることが出来る。(Operation and Effect) When resin waste is charged into the charging chamber (2) and the weight (5) is lowered by its own weight onto the waste, the resin waste is transferred to the heater chamber (3) fim by the weight. The waste is pressurized and is strongly pressed against the heater (4) starting from the lower level, and rapidly melts. Since the pressure is applied by the weight of the ji (5), the pressure is constant, and the total weight of the weight acts as a force to pressurize the resin waste into the heater chamber, so there is no excess or deficiency in the pressure.
There is no need to supply energy externally to pressurize the resin waste, and when lifting the weight, the lifting device (6
), running costs can be kept low.
