The pretreated raw materials are put into an extruder or plasticizing equipment equipped with an advanced temperature control system. Taking PP plastic as an example, in the extruder, during the rotation of the screw, through external heating and its own shearing action, the raw materials are quickly heated to the appropriate melting temperature range, gradually turning the plastic pellets into a uniform melt, preparing for subsequent molding.
