High-Accuracy HVAC Fire Damper Frame Machine

This equipment supports processing 2.0mm thick plates. Compared to conventional 1.0-1.5mm models, it is suitable for producing outer frames for fire dampers, smoke exhaust dampers, and industrial-grade air volume control valves, which require higher structural strength. The 2.0mm thick plate outer frame has higher rigidity and stronger resistance to deformation after welding, meeting the stringent testing requirements for fire resistance integrity and thermal insulation of fire protection products. Liding's core R&D team has over 30 years of experience in the cold bending forming industry, and its thick plate forming technology is mature and reliable.

Multiple forming rollers sequentially roll-form the profiles, ensuring precise cross-sectional dimensions and consistent contours. Length and diagonal errors are controlled within ±0.5mm. During welding and assembly, the four sides of the profiles are perfectly aligned without any asymmetrical gaps. The frame is square, fits tightly with the blades, and the sealing performance meets standards when the air valve is closed. Liding's senior engineering team has accumulated rich experience in roller design and debugging in the field of precision roll forming, ensuring stable and drift-free precision during long-term equipment operation.

The equipment integrates the entire process of uncoiling, cold bending, punching, and cutting. Excellent dimensional consistency is achieved in mass production of outer frame profiles. Panasonic PLC control and touchscreen operation allow for full-line monitoring by a single person. The equipment is CE certified, and core components such as the main motor, hydraulic station, and PLC are all from internationally renowned brands. Its operational stability has been verified by long-term customer use.

Each machine undergoes full-line integrated testing before leaving the factory. Complete technical documentation is provided (installation drawings, circuit diagrams, operation manuals). 12-month warranty, free spare parts replacement, lifetime online technical support, and a 48-hour response time. Liding's core R&D team has 30 years of industry experience, providing customers with full-cycle technical support from solution design and equipment manufacturing to after-sales maintenance, ensuring long-term stable operation of the equipment.
