PRODUCTS / TWIN-SCREW EXTRUDERS
A high-torque, high-output co-rotating twin-screw platform for demanding compounds, higher filler loadings and greater throughput — where specific energy and output must be pushed further than a standard series allows.
The DY series shares the modular, self-wiping architecture of our co-rotating twin-screw extruders but is built around a higher-torque gearbox and drive. This raises the available specific energy at a given screw speed, supporting higher outputs, heavier filler and fiber loadings, and more energy-intensive compounding tasks while maintaining melt quality.
Model-by-model data for the DY high-torque co-rotating twin-screw series. D = screw diameter, L/D = length-to-diameter ratio, N = maximum screw speed, P = main motor power, T = screw torque per shaft, T/A³ = specific torque grade, Q = typical operating output. DY machines run specific-torque grades of 7.1–8.7 against 4.2–9.5 on the standard SJSH platform — the reason they are specified for highly filled, high-viscosity and high-output compounding.

Catalog reference values — indicative and formulation-dependent. C denotes the high-torque class (n ≤ 500 r/min), D the high-speed and high-torque class (n ≥ 600 r/min). Output is confirmed against your material, filler loading and required kg/h.
