- Torque:
*GSD high-torque twin-screw extruders: With higher torque, usually achieved through a more robust gearbox and motor. This allows higher viscosity materials to be processed and higher yields achieved.
*GS twin-screw extruder: low torque, suitable for processing medium and low viscosity materials, relatively low output and processing capacity.

- Screw design:
*GSD high-torque twin-screw extruders: The screw design is more complex, can withstand greater shear forces and pressures, and generally has a higher length-to-diameter ratio (L/D).
*GS twin screw extruder: The screw design is relatively simple, the length to diameter ratio is moderate, suitable for the general mixing and melting process.

- Motor power and gearbox:
*GSD high-torque twin-screw extruders: Equipped with a more powerful motor and a stronger gearbox, they provide the necessary high torque and processing capacity.
*GS twin-screw extruders: With a more conventional motor power and gearbox design, suitable for medium loads and typical machining requirements.

- heating and cooling systems:
*GSD High-torque twin-screw extruders: More efficient heating and cooling systems are needed to manage the increased heat generated by high-torque operations.
*GS twin-screw extruders: The heating and cooling system is relatively simple and designed to handle a typical processing temperature range.

- مجال التطبيق:
*GSD high torque twin screw extruder: suitable for processing high viscosity materials, high filling materials, 
engineering plastics, rubber and so on. Widely used in the mixture of high performance material, padding and modification.
*GS twin-screw extruder: Suitable for traditional plastic processing, such as PP, PE, etc., usually used in 
applications with low performance requirements.

- equipment costs:
* GSD with high torque twin screw extruder, due to the design and manufacture of the demand is higher, the cost is relatively high.
*GS twin-screw extruders: Low cost, suitable for budget applications with low performance requirements.

- Production efficiency and energy consumption:
*GSD high-torque twin-screw extruders: High production efficiency, but also relatively high energy consumption.
*GS twin-screw extruder: moderate production efficiency and energy consumption.
