Description

From 400rpm to 600rpm, even 800rpm, we have been leading the technology of twin screw extruder in China. Our new SAT series twin screw extruder has brought specific torque up to 10.3Nm/cm3 setting a new standard of China-made twin screw extruders.

Stability and productivity are at the foundation of our basic principles. All extruders have been tested by production including modular design of screws.

All of our extruders have been tested in production. Modular design of screws and barrels make our machine more flexible. This allows for one machine capable of multi-applications. A pleathera of screw geometry and barrel structure are available for all kinds of processing. We will customize extruders according to customers’ individual processing purpose.

We enjoy sharing our laboratory extruders with our customers. This helps us to develop new applications, new materials, and new recipes.

Product Model

  • Machine design
    SAT is a benchmark of China-made high-performance twin screw extruder. SAT is leading the technology of China-made twin screw extruder. And since it was born in 2007, we have sold more than 500 sets of SAT series twin screw extruder whose specific torque rated at 10.3Nm/cm3.

    Its stability and productivity have been witnessed and proven by many well-known international groups’ production. Abundant screw geometry and material options are available for different processing task and different raw materials.


  • Control system
    Control system can be on-site control, and remote control is available. Our experts can diagnose your machines through an internet module. From button panel to industry computer, we can customize control system according your specific requirements and budget.


  • Application
    SAT has been widely used in processing of polyolefin, engineering plastic, masterbatch, PVC, and food. Using SAT in direct extrusion is also gaining ground. From conveying, through raw materials feeding, melting, dispersing, homogenizing, devolatilizing, pressure build-up, probably cooling and filtering, and pelletizing or extrusion molding, every single step has to be precisely fit the specific application.
