Blow molding machine is one of the basic equipment of the plastics processing, for processing all types of plastic bottles, buckets, boxes and other products, the device has two parts: extrusion unit and forming unit, extrusion unit part of the extruder principle, Usually screw extruder, the molding unit, the raw material is heated by the mold and the vacuum blowing extrusion adhered to the inner wall of the module by blowing compressed air into the cavity and cooled to form a hollow article. Blow molding machines, extrusion unit are controlled by inverter motor speed adjustment screw extrusion capacity, according to the different products, and molding unit and mold, mold, mold movement through hydraulic transmission, in order to reduce the energy consumption of the pump motor inverter control, and mold, mold different process requirements to adjust the motor speed over to.
