- Features of Extruder: This new extrusion system brings together the familiar superior plasticization and homogenization of a parallel twin-screw extruder with the specific advantages of the conical twin-screw system. The screw is equipped with easy changeable shear and mixing elements which allow adjusting the plasticizing exactly to each demand. Effective degassing supported by a vacuum pump removes monomers in the front of the plasticizing unit • Big intake section / very good in-feed behavior • Conical design ensures very good screw filling  • Therefore, high output per screw rotation (kg/rpm)  • High torque possible because of huge screw shaft diameter • Very stable pressure behavior  • Excellent homogenizing offered by the co-rotating system • Excellent feeding performance • Small melt dwell time distribution inside the processing unit • Therefore low melt temperature • Therefore low energy consumption -   Features of SSP In the SSP process, the PET pellets are further decontaminated and their molecular weight is increased to obtain high-quality bottle grade resin, which meets the regulations of the authorities and requirements of the packaging industry. SSP and decontamination of migrated substances are diffusion controlled processes. The main design parameters are product temperature and residence time. The solid-state polycondensation process (SSP) is required to upgrade the molecular weight of the amorphous PET pellets to high-quality bottle grade resin, which meets the regulations of the FDA and requirements of the packaging industry. • Especially suitable for small and medium enterprises in the third world countries which has no polymerization facility.  • High I.V. chip downstream users • Stable performance, economic investment and high C/P value. • Long-term experience and quality control method of washing line will provide excellent and stable quality of PET flakes for continuous and stabilized feeding of pelletizing and SSP. • Energy-saving and environmental-friendly: reuse heat energy from pelleti
