Double layer roll forming machine in India

Double layer roll forming machines are designed to produce two different metal profiles in one machine, making them a versatile and space-efficient option for production. Here are the typical specifications and descriptions of a double-layer roll forming machine:

1. General Specifications

• Material Thickness: 0.2-1.0 mm (for lighter materials like aluminum or soft metals) up to 1.5 mm for heavy-duty applications.
• Material Width: Varies based on profile requirements but typically ranges from 600 mm to 1,250 mm.
• Material Type: Galvanized steel, aluminum, copper, or coated steel.
• Machine Dimensions: Length (6-12 meters), Width (1.5-3 meters), and Height (1.5-3 meters) depending on machine complexity and profile types.

2. Profile Types

• Top Layer: Configured for one profile, such as trapezoidal or corrugated sheets.
• Bottom Layer: Configured for a different profile, e.g., standing seam or different corrugated style.
• Profile Changeover: Manual or automated selection allows switching between the two profiles without time-consuming die changes.

3. Key Components

• Decoiler: Typically handles up to 5-ton coils, with options for manual or hydraulic operation.
• Feeding System: Guides the sheet smoothly to prevent misalignment.
• Roll Forming System: Two independent sets of rollers, one for each profile, providing high precision and durable shapes.
• Cutting System: Hydraulic cutting system that precisely trims both profiles without burrs or distortions.
• Control System: PLC-based, user-friendly interface allowing for easy adjustment of production parameters, including profile type and length of sheets.
• Hydraulic System: Powers the cutting and changeover process, with oil cooling to ensure reliable performance under continuous operation.

4. Performance

• Production Speed: Typically 10-20 m/min, adjustable depending on the thickness and material type.
• Motor Power: Ranges between 5-15 kW for each layer, depending on material thickness and speed requirements.
• Power Supply: Configurable to meet local standards (380V, 50Hz, 3-phase or as required).

5. Applications

• Double-layer roll forming machines are ideal for manufacturers producing roofing sheets, wall panels, and decorative metal profiles where space or cost limitations require flexible production on one machine.
• Industries like construction, roofing, and agricultural storage benefit significantly from these machines due to the variety of profiles they can produce.
