Plastic is melt into homogeneous melt plastics by a twin screw extruder, and can make the head of the extruder with constant temperature, constant quality and constant pressure under the pressure created in the process of plasticization. This is also the way which is used on most thermoplastic plastic. Extruders have different kinds of type and etalon,among which twin screw extruder is the most common one.

The technological requirement can be satisfied and the technological control index can be reached by the wheeling of the mainframe of twin screw extruder, which uses the kv2000 AC frequency converter.
 
From long stable practical operation of each place, it is obvious that twin screw extruder has a strong adaptability that can bring significant economic benefits to our society.
