Key Features

High-Shear Melt Homogeneity
Optimized screw geometry ensures uniform plasticization and steady head pressure, eliminating thermal degradation and melt temperature fluctuations.

Precision L/D Ratio Optimization
Configurable L/D ratios (such as 25:1, 30:1, or 33:1) with vented barrels ensure optimal residence time and volatile degassing.

Extrusion Output Stability
High-torque reduction gearboxes paired with synchronous motor drives maintain steady output without surging during continuous operation.

FAQ

Q: What are the primary manufacturing applications for this single screw extruder?

A: It delivers continuous melting, compounding, and profiling of thermoplastic media into rigid pipes, blown films, sheet profiles, and wire insulation coatings.

Q: What specific polymer matrices and raw materials can the system process?

A: The system processes standard industrial thermoplastics including HDPE, PP, PVC, ABS, PS, and PET in both pelletized and regrind formats.

Q: What is the operational screw speed range for the Φ90 mm configuration?

A: The screw operates within a variable 10 to 120 rpm spectrum, adjusted via inverter drives to match melt viscosity and shear requirements.

Q: How do we determine whether a single screw or twin screw extruder is required?

A: Single screw configurations are engineered for stable pressure output during profile extrusion and pellet shaping, whereas twin screw systems are utilized for high-shear polymer compounding, masterbatch mixing, and reactive alloying.
