Contact each other. However,
Since the artificial graphite material has good thermal conductivity, if the press cylinder is heated with a graphite heater or induction heating,
It was difficult to dissipate the heat energy through the cradle 1 and the push rod 5 and consume the electric power, thus making it possible to reduce the cost.
