The appropriate temperature is set through a temperature controller, and heating treatment is carried out by a single-head dry-burning electric heating tube. After the PP powder melts, it is then solidified. The time relay is controlled by a selection switch for timing operation. During this period, the relevant personnel need to stir the molten PP powder until it is close to solidification.
