Description:

The Kiefel 40mm Blown Film Line, Model CA4 is a versatile lowboy extruder system designed for precision film extrusion applications. This system is equipped with a 24:1 L/D extruder featuring an electrically heated, air-cooled barrel and includes a second complete barrel, screw, and heaters to convert it to a 30:1 L/D ratio, allowing for process flexibility.

Powered by a 30 HP Reliance DC motor with SCR control, the belt-driven gearbox ensures efficient torque transmission, and the water-cooled gearbox with grooved feed throat optimizes melt quality and extrusion performance.

The operator control panel provides seven (7) temperature control zones, including:

• (4) Barrel zones
• (3) Die zones
• Blower control
• Speed control dial
• Extruder monitoring for Amps, RPM, pressure, and melt temperature

This system includes a 3” stationary blown film die (less air ring) and a 6.1 kW air ring blower with a 4-port plenum, ensuring efficient film cooling and production stability.

The Kiefel FW 811 single-position surface winder accommodates 36” diameter rolls and is equipped with:

• Winder operator control panel with preset footage counter
• Auto fly knife & auto transfer
• Second pull roll assembly
• Two winding shafts

With 460V 3-Phase 60Hz power input, this well-maintained blown film extrusion line is ideal for flexible film manufacturing applications.
