Product Description

Advanced Dual-Profile Manufacturing System for Maximum Floor Efficiency of C8 and C20 double layer roll forming machine

Cangzhou Zhongtuo Roll Forming Machinery Co., Ltd. presents the C8 and C20 double layer roll forming machine, an industrial-grade dual-level cold forming system designed to produce two distinct steel profiles on a single consolidated chassis. This equipment manufactures C8 low-wave profiles (8mm height for wall cladding and fencing) and C20 trapezoidal profiles (20mm height for structural roofing) with precision.

The machine reduces factory floor space by approximately 50% compared to operating  separate lines. With 17 forming stations, a forming speed of 15-20 m/min, and compatibility with 0.3-0.8mm material thickness, this product delivers exceptional capital efficiency. The 300mm H-steel main frame ensures structural rigidity for continuous operation, while the hard chrome-plated rollers (0.05mm coating) protect pre-painted surfaces during forming.

Versatile Applications Across Construction Sectors

Your production needs determine the value of this equipment. The C8 layer produces subtle low-depth profiles ideal for residential fencing, ceiling panels, and decorative facades. These applications dominate CIS and European markets where architectural aesthetics matter.

The C20 layer generates trapezoidal sheets essential for warehouses and commercial roofing. These profiles provide superior water drainage and load-bearing capacity against environmental stress. You gain the flexibility to serve both residential and industrial clients without investing in separate production lines.

For remote construction sites, this solution becomes invaluable. You can fabricate both interior liner panels and exterior roof skins on-site, eliminating transit damage and reducing logistics costs significantly. The containerized mobility option transforms your operational efficiency.

Precision Engineering and Quality Assurance

​​​​​​​The machine operates through an asynchronous system using clutch mechanisms or dual-motor configurations. You activate only the required layer, optimizing energy consumption and reducing mechanical wear. The industrial-grade PLC control ensures dimensional accuracy within ±1mm tolerance.

Our quality control protocols include dimensional overlay tests against CAD drawings, surface integrity inspections, and full-load run tests lasting 2-4 hours. The hard chrome rollers rotate synchronously to prevent surface drag on coated materials. The hydraulic cutting blade produces burr-free edges, preventing corrosion initiation points.

The 70mm solid steel shafts withstand continuous industrial operation. The heavy-duty H-beam welded base supports vertical loads from dual shaft systems without torsional vibration. This structural integrity ensures consistent profile geometry compliant with international building standards.

Operational Efficiency and Smart Control

Switching between C8 and C20 production takes less than 2 minutes. You select the desired profile on the touch screen, and the PLC cabinet automatically engages the corresponding clutch system. This rapid changeover capability maximizes your production flexibility.

The forming speed of 15-20 m/min balances output volume with profile precision. Material handling accommodates yield strengths from G300 to G550 MPa, allowing you to work with various steel grades. The 17 forming stations gradually shape the metal, preventing spring-back issues common with high-tensile materials.

Energy efficiency comes from selective layer operation. When producing C8 profiles, the C20 shaft remains disengaged, reducing power consumption. The 4KW hydraulic station provides sufficient cutting force while maintaining operational economy.

FAQ

Q:Can both profiles be produced simultaneously?

A:No, only one layer operates at a time for motor longevity and safety. The clutch mechanism directs power to either the C8 or C20 shaft level.

Q:How long does profile switching take?

A:Switching happens through the PLC touch screen in under 2 minutes. The system automatically engages the corresponding gear and clutch mechanism.

Q:What determines machine lifespan?

A:Frame rigidity (typically 350H or 400H beam) and shaft bearing quality determine longevity. With proper lubrication, expect over 10 years of industrial service.

Q:Are cutting systems separate for each layer?

A:High-end models feature two separate hydraulic cutting dies mounted on the same post-cut frame, ensuring blade geometry matches the active profile perfectly.

Q:Can it handle high-tensile G550 steel?

A:Yes, when specified during design. Processing high-tensile material requires the full 17 forming stations to gradually form metal and prevent spring-back defects.

Q:What maintenance schedule do you recommend?

A:Lubricate bearings every 500 operating hours. Inspect roller chrome plating monthly for wear. Replace hydraulic oil annually for consistent cutting performance.
