SJFM-1700D Double Main Frame Film Extrusion Laminating Machine

Brand: OUNUO
Manufacturer: Zhejiang Ounuo Machinery Co., Ltd. (China)
Model: SJFM-1700D
Application: Designed for double-sided polymer coating (extrusion lamination) or forming multilayer combined packaging materials in one technological cycle.
Operation: New equipment.

Technical characteristics:
Configuration: Double Mainframe — two autonomous extruders for coating on both sides in one pass.
Working width: 1600 mm (maximum roll width on unwinding — 1700 mm).
Lamination speed: Design speed up to 150 m/min (working speed 100–120 m/min).
Temperature range: 150°C – 320°C (optimal for working with LDPE, PP, EVA, as well as biodegradable polymers PLA/PBS).
System heating time: 90 – 150 minutes before entering the operating mode.
Number of rollers/shafts: 40 pcs. (including mirror cooling and pressure silicone rollers).
Electrical parameters: Total power 110 kW, voltage 380 V, current frequency 50 Hz.
Included: Two autonomous extrusion units with an extrusion head (T-Die) 1700 mm wide.
Two-position automatic turret unwinding and winding system (Turret Unwind/Rewind) for continuous roll change at speed (Non-stop). The machine is equipped with 2 main unwinders and 2 winders operating in non-stop (reversible) mode for quick roll change without reducing speed and stopping the line.
Highly efficient corona discharge station (coronator) for activation and preparation of the substrate surface.
Centralized automatic web tension control system based on PLC with touch HMI control panel.
Massive compression unit for rapid cooling of the melt (Chilling Rollers).
Precision edge trimming system with disk knives with vacuum waste suction.
Year of manufacture: June 2024
