🏭 Manufacturer Information

Manufacturer: Welex

Model: HS 3.0 40D SV

Type: Single Screw Extruder

Serial #: 8454

Year Built: 2009

⚙️ Product Description

This Used Welex HS 3.0 40D SV Single Screw Extruder is a high-performance processing line ideal for plastics extrusion applications requiring consistent melt quality, high throughput, and robust reliability.
Featuring a 3-inch screw diameter with a 40:1 L/D ratio, this extruder delivers efficient melting, mixing, and pressure development. The barrel is electrically heated and air cooled, with a vented section for devolatilization. A 57" barrel center line and an oversized 3” × 9” water-cooled feed throat improve material intake for higher-rate processing.
Equipped with a 550 HP (412 kW) direct-drive variable frequency motor, this extruder supports high screw speeds—up to 1520 RPM—making it suitable for demanding applications such as sheet extrusion, compounding, profile extrusion, and more.
An integrated touchscreen control system provides full process oversight and precision adjustments.
