The Welex HS 3.0 40D SV is a single-screw plastic extrusion machine manufactured in 2009, designed for high-speed, continuous processing of thermoplastic materials. It features a 3-inch diameter screw with a 40:1 length-to-diameter (L/D) ratio, offering enhanced mixing, higher output, and improved melt homogeneity. This model is vented and plugged, suitable for efficient devolatilization during extrusion.
The extruder is equipped with an electric heated and air-cooled barrel system, ensuring precise temperature control across multiple zones. It includes a 57-inch barrel centerline and an oversized water-cooled feed throat measuring 3 inches by 9 inches. The machine is directly driven by a 412 kW ABB AC motor paired with an ABB Variable Frequency Drive, capable of 680 amps at 480 volts, 3-phase, 60 Hz power input. The motor delivers 412 kW (approximately 550 horsepower) for robust performance.
Control is managed via a touchscreen operator panel, allowing for precise adjustments to process parameters. The maximum screw speed reaches up to 1520 RPM.
Visible components include a large conical hopper for raw material feeding, multiple heating zones along the barrel, and a cooling fan mounted on the motor cover to assist thermal management. The electrical control panel is open in the images, showing organized wiring with tagged cables, circuit breakers, contactors, and relays, indicating a well-maintained electrical system. Some oil or grease stains are noted on the base platform, which is typical for used industrial equipment.
This extruder is suitable for producing plastic sheets, profiles, and compounds from various thermoplastics, offering reliable and consistent operation for demanding industrial applications.
