The C-shaped roll forming machine, with its technological advantages, has become a core piece of equipment in the production of steel structure building materials. Its performance directly improves production efficiency and product quality.
High-efficiency and continuous production are its core features. Utilizing a cold roll forming process, it eliminates the need for preheating the metal sheet. Continuous rolling through 15-25 sets of rollers achieves a processing speed of 10-30 meters per minute. A single 8-hour shift can produce 15,000 meters, 5-8 times the throughput of traditional welding processes. This meets the mass production needs of large-scale orders and significantly shortens delivery cycles.
The forming accuracy is industry-leading. The precision-ground roll die, coupled with a servo motor-controlled feed system, ensures that the C-shaped cross-section's dimensional tolerance is strictly controlled within ±0.5mm, with a straightness tolerance of no more than 1mm/m. This high precision ensures that the purlins are installed without secondary processing and can be bolted directly to the main steel structure frame, significantly reducing construction costs.
The material utilization rate exceeds 95%. The continuous rolling process eliminates shear waste associated with traditional stamping, saving approximately 1.2 tons of steel per 10,000 meters of purlin. Based on an annual production capacity of 1 million meters, this translates to an annual material cost savings of over 100,000 yuan. Furthermore, the cold-bending process preserves the steel's original mechanical properties, resulting in a 15%-20% increase in compressive strength compared to hot-rolled steel.
The machine offers exceptional operational flexibility. The PLC touchscreen allows for quick configuration of parameters such as purlin length and thickness. Changing molds takes only 20-60 minutes, allowing production of C-shaped parts in various specifications, ranging from 80-300mm in width and 0.8-3mm in thickness. This meets the diverse needs of buildings with spans of 6-15 meters, such as small and medium-sized factories and warehouses. The equipment also features a built-in fault diagnosis system that monitors roller status and plate deflection in real time, automatically shutting down and alarming in the event of an anomaly, reducing manual intervention costs.
The company boasts significant advantages in energy consumption and maintenance costs, saving over 60% compared to hot-rolling processes. The rolls are made of alloy steel with a hardness of HRC55 or higher, resulting in a service life exceeding 500,000 meters. Annual maintenance costs account for less than 3% of the equipment's total price. The C-shaped purlins it produces, with their compact cross-section and light weight, can reduce overall building loads, helping achieve green building standards. They are crucial equipment for building materials companies in reducing costs, increasing efficiency, and expanding their market share.
