This machine combines the advantages of twin-screw and single-screw extruders to ensure optimal performance, stability, and efficiency. #### Key Features of the Two-Stage Extrusion System: - **First Stage (TSE Twin-Screw Extruder):** Equipped with a barrel and screw system, this stage is ideal for processing heat-sensitive materials such as PVC, XLPE, and HFFR. It excels at melting, compounding, dispersing, and decentralizing under controlled back pressure conditions. - **Second Stage (SJ Single-Screw Extruder):** Operating at a lower speed, this stage ensures steady melting, lengthwise compounding, and strand formation, reducing the risk of overheating and maintaining product quality. - **Operational Flexibility & Temperature Control:** The system allows for precise temperature control and easy adaptation to different production processes, significantly enhancing productivity and output consistency. - **Ideal for Sensitive Materials:** This machine is especially effective for processing materials like **PVC**, **XLPE**, and **HFFR** that are sensitive to heat and shear stress. --- ### Technical Data Table | Model | TSE Screw Diameter (mm) | L/D Ratio | Screw RPM | Motor Power (kW) | Capacity (kg/hr) | |-------------|---------------------------|------------|------------|------------------|-------------------| | SP50-120 | TSE-50 | 24–48 | 500 | 37–45 | 150–300 | | | SJ-120 | 7–20 | 65–85 | 30–37 | 150–300 | | SP65-150 | TSE-65 | 24–48 | 400–500 | 55–75 | 200–500 | | | SJ-150 | 7–20 | 65–85 | 37–45 | 200–500 | | SP75-180 | TSE-75 | 24–48 | 400–500 | 90–110 | 300–600 | | | SJ-180 | 7–20 | 65–85 | 45–55 | 300–600 | | SP95-200 | TSE-95 | 24–48 | 300 | 160–220 | 500–1000 | | | SJ-200 | 7–20 | 85 | 90–110 | 500–1000 | --- ### Additional Applications of Two-Stage Extrusion - **Fiber Reinforcement:** Glass fiber, carbon fiber reinforced polymers such as PP, PA, PBT, ABS, AS, PC, POM, PPS, PET, etc. - **Polymer Blending:** Blending of PC/ABS, PA/ABS, CPE/ABS, PP/EPDM, PA/EPDM, PP/SBS, etc. - **Filler Incorporation:** CaCO3, Talc, TiO2, carbon black filled PE, PP, EVA, etc. - **Cable Compounds:** Sheath, insulation compounds for LDPE, HDPE, LLDPE, MDPE, radiation-crosslinkable compounds, optical fiber protection, heat-shrinkable polymers. - **Special Compounds:** PPR pipe compound, crosslinked pipe PE compounds, tobacco filter compounds, high-concentration color masterbatches (PP, PA, ABS, EVA, PBT, etc.). --- ### Certifications This machine is certified with **CE, ISO, TUV, and SGS**, ensuring compliance with international standards and guaranteeing the quality and safety of the equipment. --- ### Contact Us In addition to the **two-stage extrusion system**, we also offer **twin-screw extrusion** and **single-screw extrusion** systems for your reference.
