The unique configuration of the Two-stage extruder machine is designed to combine the excellent mixing performance of the high-speed parallel Twin screw extruder with the advantages of the low-speed single-screw extruder’s low-temperature stability for a more efficient production process and better product output.

The Two-stage machine is characterized by its unique structural design. The first stage is the GTE high-speed parallel Twin screw extruder
, which uses the high dispersion and strong shear of the twin screw to complete the plasticization and dispersion quickly and fully. At the same time, because the screw is a building block structure, the screw combination can be adjusted arbitrarily according to different materials in order to achieve the best mixing state of the material. The second stage is GDE low-speed single-screw extusion machine, used for low-temperature extusion, due to the single-head deep groove structure of the single screw, which helps to stabilize the pressure of the melt in the extusion process, the single-screw barrel is equipped with heating and cooling, which can accurately control the extusion temperature and avoid excessive decomposition of the melt. Two-stage extusion machine combines the characteristics of high speed and strong mixing of twin screw and the characteristics of low speed, low temperature and weak shear of single screw, maximize the advantages of equipment and greatly improve production efficiency. The two machines are placed vertically to save space and provide continuous production line layout.
