SK Series Twin screw extruders have the following advantages:


High-efficiency transmission system


  • The SK Series Mini Twin screw extruder adopts the high speed and high torque transmission system of Henschel of Germany. The screw has a maximum speed of 900 rpm. and a torque of 13 Nm/cm³. The system of K Series Twin screw extruder adopts the latest design of Henshl, and the overall strength and gear system stability are greatly improved. At the same time, the system is smaller and equipped with more powerful lubrication and cooling system, which enables users to use extruders safely and quietly.


  • British BiBBY torque limiter with high sensitivity and reliability can effectively avoid equipment shutdown due to improper operation or accidental overload.


  • Siemens's global joint insurance ILE0 series inverter motor has the characteristics of high efficiency, energy-saving, safety and so on. It provides technical support and service for localization.


Optimizing Processing Section


  • The processing section of the SK series double screw extruder can be flexibly configured for transportation, plasticization, mixing, shearing, homogenization, devolatilization and pressure according to the technological requirements of users' materials.


  • The screw and barrel can be made of HIP powder metallurgy material, which can achieve high wear resistance, high corrosion resistance and other extensive fields of operation.


  • The involute spline of the German standard (DIN5480) is adopted to meet the requirements of higher torque and higher speed.


  • Optimized screw size-diameter ratio (D0:D=1.55), reliable inter-model amplification effect


Internet-based New Generation Control System


  • The control system of SK series twin screw extruder can choose conventional instruments, PLC, PCC, DSC to meet different needs.


  • Modular design, the touch screen can be compactly installed on the mainframe


  • Customized programming design is satisfied with the upstream and downstream matching equipment of different mixing projects


  • Provide formulation, project management functions, process and production data visualization


  • Integrating computer technology, mobile Internet technology and industrial automation technology to realize real-time data management and control of multi-terminal
