This slot-type cable tray cold bending machine integrates opening, leveling, online punching, continuous roller pressing cold bending, servo fixed-length cutting, and material stacking. After the galvanized steel strip is sent to the production line, it is formed into a complete slot-type cable tray in one step, without the need for secondary processing. The equipment uses multiple precision rolling rollers for progressive cold bending forming, with a forming size error controlled within ±0.5mm, good slot body straightness, regular bending edges, strong finished product rigidity, and effectively guarantees the later cable tray jointing and installation accuracy. It is equipped with a PLC touch control intelligent system, allowing parameters to be set quickly, and it can quickly switch between various cable tray specifications, suitable for different width and height slot-type cable tray production. It is multi-purpose in one machine. The production line operates stably, forms quickly, significantly reduces the number of workers, reduces material loss, and improves production capacity. The equipment is compatible with various raw materials such as galvanized plates and color steel plates, and the produced slot-type cable trays are widely used in data centers, factory distribution, rail transit, photovoltaic and wind power, building construction, etc., meeting the requirements for the protection of strong and weak wire cables. The equipment adopts a modular structure design, is convenient for maintenance, supports customized functional upgrades, and can be connected to the existing automation production lines. Based on mature equipment research and manufacturing capabilities, it can provide customers with equipment debugging, technical training, and integrated after-sales operation and maintenance services, helping cable tray manufacturing enterprises achieve automation upgrades, reduce costs, increase efficiency, and empower the high-quality development of domestic and foreign power infrastructure supporting industries.

L-edge Angle Steel Profile Machine: Cold bending forming technology empowers the new infrastructure of architectural decoration.
02 Sep, 2026
Product Positioning and Core FunctionThe L-edge angle steel profile machine is a cold bending forming equipment specifically designed for manufacturing L-shaped cross-section steel profiles. The L-shaped profiles, as an important component of the steel profile system, are mainly used for connecting the ceiling and walls and reinforcing the corners of partition walls. In practical applications, this product can effectively solve problems such as warping of the edges and corners of the sheet material and unsightly gaps, thereby enhancing the overall decorative effect. Steel profiles are classified by cross-sectional form into various specifications such as V-type, C-type, T-type, L-type, and U-type. Among them, the L-type profiles, due to their unique right-angle structure, play an irreplaceable role in detailed construction processes such as edge finishing and corner sealing. Technical Features and Performance AdvantagesThe modern L-edge angle steel profile machine adopts the cold bending forming process. The galvanized steel strip is continuously bent and deformed through a group of gradually changing profile surfaces during the process at room temperature, ultimately forming an accurate L-shaped cross-section. This process route has significant advantages such as high material utilization rate, fast production efficiency, and good product consistency. In terms of automation control, the advanced L-type profile production line has achieved full-process automation operations. A typical production line configuration includes: an automatic two-in-one unwinding and leveling machine, a fully automatic servo tracking rolling system, high-precision and high-speed forming equipment, a fully automatic servo tracking shearing system, and core modules such as the support frame. Through the computer control system for tracking rolling and shearing, the equipment can simultaneously complete punching and cutting operations during the forming process, effectively replacing the traditional post-forming punching process, which saves labor and ensures product consistency. In terms of forming accuracy, the rollers made of high-strength mold steel such as Cr12MoV, after vacuum heat treatment, can reach a hardness of HRC58-62, ensuring long-term stable operation. Combined with the servo-driven feeding system, the feeding accuracy can be controlled within ±0.5mm, meeting the strict requirements of architectural decoration for the size accuracy of the profiles. Trend of Intelligent UpgradeCurrently, the L-edge angle steel profile machine is accelerating its evolution towards intelligence and flexibility. The PLC control system is equipped with a user-friendly touch screen interface, supporting multi-language operation and formula storage functions. Operators can quickly call up the production parameters of different specifications of products to achieve rapid model change. It is worth noting that the integration of laser cutting technology with the profile machine is becoming a new industry trend. Compared with traditional mechanical shearing, laser cutting has advantages such as smooth and hairless cutting edges, no contact with molds, and low noise. The cutting edge width can be controlled within 0.1- 0.3 mm. This technological breakthrough not only improves product accuracy but also enables economic small-batch and multi-variety customized production, providing a new solution for the processing of irregular components in prefabricated buildings. Market Prospects and Industry OpportunitiesFrom the investment dynamics of the steel profile equipment industry, the market for steel profile equipment remains active. For example, Guangdong Quan Tan Jing Gong Technology Co., Ltd. has a new project with a total investment of 150 million yuan, mainly engaged in the production of fully automatic universal steel profile machine production lines and conventional steel profile machines. After the project is completed, it is expected to produce 300 conventional steel profile machines annually. This investment scale reflects the continuous demand for steel profile equipment in the market. Industry analysis indicates that with the deepening of the concepts of prefabricated buildings and green construction, steel profiles, as a lightweight, high-strength, fire-resistant, and easy-to-install new type of building material, their application fields will continue to expand. From hotels, airports, shopping malls to office buildings and old building renovations, the steel profile system is playing an increasingly important role in various building scenarios. For the L-edge angle steel profile machine, the continuous expansion of the downstream application market will directly drive the growth of equipment demand. Advanced equipment with high precision, high efficiency, and intelligence will occupy a competitive advantage in this round of industrial upgrading.
