High Performance EVA POE Solar Film Extrusion Line with Precision Thickness Control 3000mm Width and 1000/1200kg/h Capacity

EVA/POE solar film extrusion line

An EVA/POE film extrusion line is a specialized industrial system designed to produce continuous sheets of EVA film by melting and forming EVA resin through extrusion. EVA films are widely used in applications such as photovoltaic (PV) encapsulation, packaging, agriculture, footwear, and laminates due to their flexibility, transparency, impact resistance, and excellent heat-sealing properties.

Key Components of the Extrusion Line

​

• 1, Raw Material Handling System

Stores and feeds EVA pellets (often blended with additives like crosslinking agents, antioxidants, or fillers) into the extrusion process.

May include dryers to remove moisture from the pellets, ensuring product quality.

• 2, Extruder

The core component where EVA pellets are melted and homogenized at controlled temperatures (typically 150–220°C).

Equipped with a screw conveyor to transport and melt the material, and a heating/cooling system to maintain optimal melt viscosity.

• 3, Screen changer

The screen changer is used to filter out foreign particles and impurities when the plasticized material flows through the filter screen. When a common screen changer is filtering, there will be dead corners. When it is restarted for the second time and extruded from the mold, crystal point lines will appear. Therefore, the belt-type screen changer is our best choice.

• 4, Melt Pump

A gear pump that stabilizes the flow of molten EVA to the die, ensuring uniform pressure and thickness in the film.

• 5, T-die

Shapes the molten EVA into a flat, continuous film by forcing the melt through a rectangular slot.

Adjustable lips allow customization of film width and thickness (ranging from microns to millimeters).

• 6, Cooling System

Chill Rollers/Calender: Rapidly cools the molten film to solidify it, improving surface smoothness and dimensional stability.

Air Knife/Quench Tank: Optional for specific applications, providing additional cooling or surface treatment.

• 7, Edge Trimming & Recycle System

Cuts excess material from the film edges and recycles trimmings back into the extrusion process for efficiency.

• 8, Thickness Scanner

The thickness scanner can be used to measure the thickness of the cast film online and output it in the form of an electrical signal. During the process of cooperating with the automatic mold, this electrical signal is sent to the display and the automatic thickness control system to achieve the automatic thickness control of the film.

• 9, hual-off Unit

Uses powered rollers to pull the film at a controlled speed, ensuring consistent tension and preventing stretching or sagging.

• 10, Winding System

Rolls the finished film onto cores in neat, tension-controlled rolls, ready for storage or further processing.

• 11,Control Panel & Automation

Integrates PLC (Programmable Logic Controller) or computer systems to monitor and adjust parameters like temperature, speed, and pressure in real time, ensuring precision and consistency.

Working Process

Material Preparation: EVA pellets and additives are mixed and dried to remove moisture.

Extrusion: The mixture is fed into the extruder, where it melts and forms a homogeneous melt.

Die Extrusion: The melt is forced through the die head to form a flat film.

Cooling & Solidification: The film is cooled on chill rollers or via air/liquid quenching to set its structure.

Traction & Trimming: The film is pulled by rollers, trimmed to the desired width, and excess material is recycled.

Winding: The finished film is wound into rolls, with quality checks (thickness, surface defects, tension) performed during the process.
