High Speed Automated Line For Welding Coating Food Grade Aluminum Cans

This Automated Can Welding & Coating Line delivers precision seam welding and food-grade coating for aluminum cans, ensuring high hygiene and durability for beverage and food packaging. The system features laser-welded seams for leak-proof integrity, followed by electrostatic epoxy coating that meets FDA standards. With speeds up to 400 CPM, it integrates automated inspection, curing ovens, and defect rejection for consistent quality. Ideal for beer, soda, and canned food producers, this line reduces material waste and energy use while maintaining ultra-low defect rates. CE-certified with PLC control, it’s built for reliable, high-volume production.

1. High-Precision Welding & Coating Process

This Automated Can Welding & Coating Line combines advanced laser welding technology with food-grade interior coating to produce seamless, contamination-resistant aluminum cans. The process begins with precision seam welding, where high-energy lasers fuse can edges without filler material, ensuring strong, smooth joints. After welding, cans undergo electrostatic powder coating, applying a uniform FDA-compliant epoxy layer that prevents beverage interaction with aluminum.

2. Key Components & Technology

✔ Laser Welding Unit – Fiber laser system with 0.1mm precision, eliminating weak seams.
✔ Electrostatic Coating Booth – Applies 5-8μm epoxy film with 99.9% coverage.
✔ Infrared Curing Oven – Dries coatings evenly at 200-220°C without overheating.
✔ Automated Inspection – Vision systems check weld integrity & coating uniformity.
✔ Defect Rejection System – Removes flawed cans before filling.
✔ PLC + HMI Control – Adjusts parameters for different can sizes/materials.

3. Technical Specifications

4. Advantages Over Traditional Methods

✅ No Contamination Risk – Laser welding avoids lead/tin solder used in older systems.
✅ Stronger Seams – Laser joints withstand 1.5x more pressure than soldered seams.
✅ Lower Energy Use – IR ovens reduce curing energy by 20% vs. conventional ovens.
✅ Zero VOC Emissions – Powder coating is eco-friendly vs. liquid sprays.

5. Quality Control Features

• X-ray Inspection (Optional) – Detects microscopic weld defects.
• Coating Thickness Gauge – Ensures FDA-compliant interior protection.
• Automated Data Logging – Tracks weld/coating metrics for traceability.

6. Applications

• Beer & Carbonated Drinks – Pressure-resistant welded seams.
• Canned Foods – Acid-resistant epoxy coating (tomatoes, juices).
• Pharmaceutical Cans – Sterile, particulate-free interiors.

7. Compliance & Support

• CE, FDA 21 CFR, EU 10/2011 certified.
• Turnkey installation & operator training.
• 2-year warranty on laser & coating systems.
