Introduction
The document describes the AMUT extrusion line designed for producing foil in special materials such as EVA, cross-linked EVA, and TPU, primarily for solar panel production. The photovoltaic sector is rapidly growing globally and is crucial for alternative energy.

Material Specifications
The material used, EVA, is enhanced with light stabilizers, cross-linking agents, peroxides, and other components. Cross-linking is achieved through post-curing in autoclaves or IR ovens after extrusion.

Extrusion Line Features
The extrusion line must produce foil with maximum light transmission and prevent cross-linking during the process. It includes a precise temperature control system and a specially designed screw and barrel made from special materials. A gravimetric dosing system feeds both liquid and solid additives.

Extruder and Calender Unit
The extruder feeds a special flat die tailored for low-flow materials. The calender unit, with three independently driven rolls, features a special cooling system and anti-stick coating. The cooling phase is progressive and controlled, with a temperature range from 15°C to 130°C.

Thermal Stabilization and Winding
After the main rolls, the foil undergoes thermal stabilization. An additional roller-set ensures controlled final cooling. The line includes an unwinding and control unit for hot or cold lamination. A semiautomatic winder completes the line, allowing for direct or protective film winding.
