Seam Protection & Curing System
For Internal & External Weld Line Protection of Three-Piece Cans
The UMAR Seam Protection and Curing System is engineered to provide reliable and effective protection for the welded seam of three-piece cans, ensuring long-term durability, corrosion resistance, and food safety.
This compact, high-performance unit can be seamlessly integrated after any brand of Can Body Welder and is compatible with a variety of production line configurations.
System Highlights
- Complete Weld Line Protection
- Internal Seam Protection: via automatic powder spray application
- External Seam Protection: using a precision wet lacquer roller coating system
Advanced Curing Technology
- Available in Induction Heating, LPG, or Natural Gas versions
- Designed for efficient polymerization of seam protection lacquers and/or powders
- Equipped with two straight heating heads for even and controlled curing
- Total heating length: 3 meters, ensuring full seam coverage and durability
Precision Can Handling
- Can bodies are transported via a single conveyor belt
- Integrated magnetic rails keep each can aligned on the central axis during movement
- Adjustable conveyor belt speed allows tuning for different production requirements
Modular & Safe Design
- Straight-line modular build with compact footprint
- Full safety protection covers across all heating and transport zones
- Designed for easy maintenance and integration into existing lines
Smart Control System
- Central PLC control unit monitors and manages all process parameters
- Ensures consistent application, reliable curing, and production efficiency
Typical Line Configuration
This system is commonly installed directly after the welding machine and before downstream processing to protect the can seam prior to further finishing (e.g., powder coating or labeling). Especially important for food-grade cans, where durability and contamination prevention are critical.
