GWELL EVA/POE Solar Film Extrusion Line: A Technical Overview

As global demand for photovoltaic (PV) modules continues to surge, the production of high-performance encapsulation films has become critical. GWELL has developed an advanced EVA/POE/EPE solar film extrusion line that meets the stringent requirements of modern PV manufacturing. This article provides an in-depth analysis of the system’s design, capabilities, and market positioning.

Headquartered in Yancheng, Jiangsu, GWELL specializes in polymer processing equipment with a focus on PV applications. The company combines precision engineering with practical innovation, offering solutions tailored to mid- to large-scale solar film producers.

Priced at approximately ¥3.65 million, the extrusion line targets manufacturers prioritizing production stability and long-term ROI. For direct inquiries, Sales Representative Zhuang Zhuang can be contacted at +86 159 0622 0276 or via landline at 0515-8389-8188.

Core Extrusion System

Twin-screw design (Ø180mm) with 35:1 L/D ratio for optimal melt homogenization

Modular "building-block" configuration for flexible process adjustments

Dual-cavity die system ensuring uniform thickness distribution

Operational Parameters

Power supply: 380V industrial standard

Machine weight: 45,000 kg (vibration-damped construction)

Material compatibility: EVA, POE, and EPE formulations

Control Systems
While full details aren’t publicly available, industry-standard features likely include:

Multi-zone PID temperature control (±1°C accuracy)

Melt pump pressure stabilization

Thickness monitoring with closed-loop adjustment

Competitive Advantages

Production Efficiency
The combination of large-diameter screws and optimized drive systems enables output rates competitive with international equivalents.

Quality Assurance
Precision temperature management and melt filtration produce films with:

≤2% thickness variation

Minimal optical defects (gels, streaks)

Consistent adhesion properties

Operational Flexibility
The system accommodates rapid material changes—critical for manufacturers supplying both PERC and heterojunction (HJT) cell producers.

Energy Optimization
Regenerative drives and thermal insulation reduce kWh/kg consumption, addressing growing focus on sustainable manufacturing.
