PET film coating and laminating machine

for electronic componentswith lamination

Product Overview
The Electromagnetic Shielding Film Coating Machine from Shaanxi Beiren Printing Machinery is a continuous coating line engineered to apply conductive layers onto flexible substrates for EMI (electromagnetic interference) shielding films. The system supports wide web processing with precision coating control and a long multi-zone drying oven for stable curing of conductive formulations.

Key Capabilities
The line accepts PET substrates (single or dual layer) and controls coating wet weights across a broad range to address applications from ultrathin consumer films to heavy industrial shielding materials. Integrated heating options and independent zone control ensure repeatable results.

Features and Benefits

• Precision web handling and coating uniformity across full width.
• Micro-concave + comma blade coating enabling wet weights 10–150 g/m².
• 24 m oven (6 × 4000 mm) with six independent temperature zones to prevent surface skinning and ensure proper curing.
• Multiple heating methods (hot oil, steam, hot air, natural gas, electric) to match facility infrastructure.
• Production speed adjustable up to 60 m/min to balance throughput and coating quality.

Coating & Drying Options
Coating method: Micro-concave + comma blade coating.
Coating wet weight range: 10–150 g/m².
Drying oven: 6 zones × 4000 mm = 24,000 mm total; six independent temperature zones for precise control.
Available heating/drying methods:

• Hot oil heating — stable temperature profiles.
• Steam heating — energy-efficient option.
• Hot air heating — enables fast solvent evaporation.
• Natural gas heating — option based on facility energy choices.
• Electric heating — alternative energy option.

Why Choose This Solution
The system is designed to deliver uniform conductivity, reliable adhesion through downstream converting (die-cutting, lamination) and high surface quality required for demanding EMI applications such as flexible printed circuits, automotive sensors and medical imaging components.

Applications

• Consumer electronics: ultrathin shielding films for smartphones, wearables and flexible devices.
• Automotive electronics: films for ECU cables, sensor housings and radar components.
• Medical equipment: wide-web conductive materials for imaging equipment lining and other device shielding needs.
