Description:
The Welex Model HS 3.0 40D SV is a high-performance, single-screw plastic extrusion machine designed for continuous processing of thermoplastic materials. Known for their rugged construction and precision control, Welex extruders are widely used in applications such as sheet extrusion, profile extrusion, and compounding.
What It Does
This extruder:
• Melts and homogenizes plastic resins (pellets, granules, or powders)
• Pressurizes and conveys molten polymer through a die
• Forms continuous plastic products like sheets, films, or profiles
It’s ideal for operations that require high-output, precision melt control, and consistent quality over long runs.

Capabilities
• High L/D Ratio (40:1):
Excellent for:
o Superior mixing
o Higher output
o Better melt homogeneity
o Efficient devolatilization (if vented)
• 3″ Diameter Screw:
A versatile size suitable for:
o Sheet extrusion (e.g., thermoforming sheet)
o Profile extrusion
o Lab or pilot-scale compounding
• Robust Gearbox & Bearings:
Allows long production runs under high torque loads.
• Flexible Temperature Control:
Multi-zone barrel heating ensures precise melt temperature regulation for a wide range of materials.
Applications
• Plastic sheet extrusion (for thermoforming, packaging)
• Profile extrusion (window frames, tubes, trims)
• Masterbatch or compound production
• Custom extrusion lines (when paired with downstream equipment like screen changers, dies, chill rolls)
