C8 and C20 double layer roll forming machine

C8 and C20 Double Layer Roll Forming Machine – Dual-Profile Efficiency for Modern Metal Fabrication

Our C8 and C20 double layer roll forming machine delivers exactly that. This progressed dual-level framework produces both C8 divider cladding profiles (8mm wave tallness) and C20 material sheets (20mm trapezoidal) on a single chassis. You'll spare roughly 50% of floor space compared to running two partitioned lines. With shaping speeds coming to 15-20 m/min, compatibility with 0.3-0.8mm coil thickness, and a vigorous 300mm H-steel outline supporting 17 shaping stations, this machine handles PPGI, galvanised, and aluminum materials with accuracy. Switch between profiles in beneath 2 minutes through our centralized PLC control system—no manual tooling changes required.

What Makes Our C8 and C20 Double Layer Roll Forming Machine Stand Out?

Space-Saving Dual-Layer Design

You don't need two production lines anymore. Our machine stacks two complete roller die systems vertically. This design reduces your factory footprint by half while maintaining full production capability for both profile types.

Precision Engineering for Consistent Quality

Every component matters when you're forming metal at high speeds. Here's what goes into our build:

High-grade materials throughout: We use No. 45 forged steel rollers with 0.05mm hard chrome plating. This protects your pre-painted coils from surface damage and extends roller life beyond 10 years with proper maintenance.

Heavy-duty structural support: The 300mm H-steel main frame absorbs vibration and prevents torsional flex. Your profiles come out straight, every time.

Solid 70mm diameter shafts: Made from No. 45 carbon wrought steel, these shafts handle the dual-layer load without deflection, even when processing high-tensile G550 steel.

Intelligent Control System

Production flexibility starts with smart controls. Our PLC system gives you:

·  Quick profile switching: Select C8 or C20 on the touchscreen. The system engages the corresponding layer automatically.

·  Precision cutting: Separate hydraulic dies for each profile (4KW hydraulic station) with Cr12 mould steel blades. Quenched treatment ensures burr-free edges.

·  Consistent accuracy: ±1mm dimensional tolerance maintained across all production runs.

Technical Specifications That Deliver Results

How Your Business Benefits

Lower Capital Investment

Why buy two machines when one does both jobs? Your CAPEX drops significantly while your production capability stays complete. You'll recover your investment faster through:

·  Reduced equipment purchase costs

·  Lower installation expenses

·  Decreased utility infrastructure requirements

Operational Flexibility

Market demands change. Your production line shouldn't hold you back. With our C8 and C20 double layer roll forming machine, you can:

Respond to customer orders quickly: Switch from decorative wall panels (C8) to structural roofing (C20) without production downtime.

Optimize material usage: Process the same coil stock for both profile types, reducing inventory complexity.

Expand your service offering: Take on more diverse projects without additional equipment investment.

Energy Efficiency

We designed this system with your operating costs in mind. The asynchronous operation mode means only the active layer runs at any given time. This approach:

·  Reduces power consumption by up to 40% versus running two separate machines

·  Extends mechanical component lifespan through reduced wear

·  Lowers your monthly utility bills

Where You'll Use These Profiles

C8 Profile Applications

The C8 layer produces subtle, 8mm wave profiles perfect for:

·  Architectural wall cladding: Clean, modern aesthetics for commercial buildings

·  Interior ceiling panels: Lightweight yet rigid overhead solutions

·  Decorative fencing: Durable perimeter security with visual appeal

·  Container modifications: Custom wall panels for mobile offices and storage

C20 Profile Applications

The C20 layer creates robust 20mm trapezoidal sheets ideal for:

·  Commercial roofing: Superior water drainage and load-bearing for warehouses

·  Industrial facilities: Long-span coverage with excellent structural integrity

·  Agricultural buildings: Weather-resistant protection for farm structures

·  Modular construction: Quick-assembly roofing for temporary or permanent installations

Mobile Manufacturing Solutions

Construction sites in remote locations face unique challenges. Our machine solves them by enabling on-site fabrication. You can:

·  Produce both interior liner panels and exterior roofing from a single containerized unit

·  Eliminate transit damage from hauling finished profiles

·  Reduce logistics costs by up to 60%

·  Respond immediately to field dimension changes

FAQ

Can the machine produce both profiles at the same time?

No, and that's by design. Operating one layer at a time ensures motor longevity and operator safety. Our clutch mechanism directs power to either the C8 or C20 shaft level, preventing mechanical stress and ensuring consistent profile quality.

How long does it take to switch between C8 and C20 production?

Less than 2 minutes. Your operator selects the desired profile on the PLC touchscreen. The system automatically engages the corresponding layer through the clutch mechanism. No manual adjustments needed.

What determines machine lifespan?

Two primary factors: frame rigidity and bearing quality. Our 300mm H-steel beam construction and premium shaft bearings ensure the product operates reliably for over 10 years with proper lubrication and routine maintenance.

Does each layer have its own cutting system?

Yes. High-end configurations include two separate hydraulic cutting dies—one optimized for C8 geometry, another for C20 profiles. This dual-blade system ensures clean, burr-free cuts that match each profile's specific dimensions perfectly.

Can your machine process high-tensile G550 steel?

Absolutely. When you specify this requirement during ordering, we configure the machine with additional forming stations. The gradual forming progression prevents spring-back issues common with high-tensile materials, maintaining dimensional accuracy throughout production.

How do you ensure profile dimensional accuracy?

We implement multi-stage quality control. First, CAD overlay testing verifies rib height (8mm for C8, 20mm for C20), pitch, and cover width stay within ±1mm tolerances. Then, we inspect surface integrity to confirm zero roll marks on your coated materials. Finally, full-load run tests with G550 steel verify the frame exhibits no torsional vibration that could cause ripple defects.

What maintenance schedule should I follow?

Simple routine care keeps your machine running optimally:

 Daily: Check hydraulic fluid levels and roller alignment

 Weekly: Lubricate shaft bearings and inspect cutting blade sharpness

 Monthly: Verify PLC system calibration and check frame bolt tension

 Annually: Replace hydraulic seals and resurface rollers if needed

Can you customize the machine for special profile dimensions?

Yes. Our engineering team works directly with you to modify roller dies, adjust forming stations, and configure controls for custom profiles. We've completed hundreds of customization projects for clients worldwide.
