Introduce PUTAI Technology Double Line Drywall Profile Roll Forming Machine

This double row roll forming machine is customized by our Honduras Customer. This powerhouse represents a significant evolution beyond standard single-line machines, catering to manufacturers with high-volume demands and diverse product needs.

Core Concept and Working Principle:

Imagine two complete roll forming lines operating side-by-side, perfectly synchronized within a single machine frame. That's the essence of a double line machine. It features:

1. Dual Decoilers/Uncoilers: Two independent stations hold and feed the raw material coils (steel, aluminum, etc.).

2. Separate Entry Sections: Each line has its own leveling, feeding (pinch rolls), and guiding mechanisms to prepare the strip.

3. Twin Forming Trains: The heart of the machine consists of two parallel sets of forming stations (roll stands), each progressively shaping its own strip metal into the desired cross-section profile. These lines can run identical profiles or completely different ones.

4. Independent Cutting Systems: Each line typically has its own flying cutoff press (hydraulic or servo-electric) that precisely cuts the formed profiles to length without stopping the forming process.

5. Dual Exit Handling Systems: Separate run-out tables, stacking systems, or bundling equipment handle the finished products from each line.

6. Centralized Control System: A sophisticated PLC or CNC control system manages and synchronizes both lines, allowing for independent setup, operation, and monitoring.

Key Advantages:

1. Dramatically Increased Production Capacity: The most obvious benefit. A double line machine can theoretically produce twice the output of a comparable single-line machine running the same profile, effectively doubling throughput without doubling floor space proportionally.

2. Space Efficiency: While larger than a single line, a double line occupies significantly less space than installing two completely separate single-line machines, optimizing valuable factory floor real estate.

3. Production Flexibility & Versatility:

   • Identical High-Volume Production: Run the same profile on both lines for massive output.

   • Diverse Profile Production: Run two different profiles simultaneously, catering to varied customer orders or product lines without changeover downtime on either line.

   • Material Flexibility: Process different materials (e.g., steel on one line, aluminum on the other) or different thicknesses/coatings concurrently.

4. Reduced Operational Costs (Per Unit): By sharing the machine frame, control system, and potentially some auxiliary systems (like hydraulic power units), capital investment per unit of output is often lower than for two separate machines. Labor efficiency also increases as one operator can often manage both lines.

5. Optimized Changeovers: When running different profiles, changeovers on one line can potentially be performed while the other line continues production, minimizing overall downtime.

6. Risk Mitigation: If one line experiences a technical issue requiring stoppage, the other line can often continue running, maintaining partial production.
