Technical Features

1) Twin screw combination technology

Years of accumulated experience in R&D and design of twin-screw configuration are optimized and combined with advanced software technology. Special double-threaded elements and unique screw combinations can realize conveying plasticization, mixing and mixing, shearing and dispersing, homogenizing, and exhausting. Various functions such as devolatilization, pressure building and extrusion. Especially for the removal of the crystal water inside the PET material, it has a very high efficiency. The specially designed exhaust port does not emit material, and is free and unobstructed. It realizes low-temperature extrusion and avoids the thermal degradation of PET;
2) Vacuum exhaust technology
Multi-stage forced exhaust is efficient and safe to ensure that the PET material will not be hydrolyzed or crystallized during the melting and plasticizing process. Special three-stage vacuum exhaust technology and oil-gas separation technology, super large pumping capacity and super high vacuum, greatly reduce the viscosity reduction of PET.
3) Spiral flow channel technology inside the high-strength roller
The internal spiral flow channel structure design of the high-strength roller is equipped with a water temperature control system, so that the roller has precise temperature control and efficient heat transfer effects;
