Why Choose This Machine?
One production line replaces the entire manual fabrication workshop
Before adopting this equipment, the production of fire damper frames required 5-6 skilled workers to complete the whole process of manual bending, cutting, welding and correction, with low efficiency, high labor cost and unstable quality. This LD-FD05 fully automatic production line realizes the whole process of unmanned continuous production after parameter setting, only one worker is needed to monitor the equipment operation and finished product discharging. With a stable production speed of 8m/min, the output of the equipment in one hour exceeds the full-day output of the traditional manual team, and the labor cost is reduced by more than 80% immediately after the equipment is put into production.
Precision-formed frames with 100% pass rate of global fire safety inspections
This LD-FD05 machine is specially designed and manufactured in strict accordance with global fire safety standards and HVAC industry specifications. The 18-station progressive continuous roll forming structure, matched with high-precision hydraulic positioning and cutting system, controls the overall dimensional tolerance of the finished frame within ±0.3mm, ensuring the absolute squareness of each frame. The finished frame can be seamlessly fitted with all standard damper blades on the market, forming a complete airtight seal after assembly. Our customers have verified that after switching to this equipment, the fire inspection failure rate of the produced damper frames is zero, completely eliminating the rework cost and project delay caused by unqualified products.
Industrial-grade heavy-duty structure, built for 15+ years of non-stop reliable service
This is a professional industrial-grade production equipment completely different from the low-cost light models on the market. The main body of the equipment adopts an integral thick steel plate welded frame with a net weight of 9000kg, which undergoes strict overall stress relief annealing treatment after welding, completely eliminating the vibration of the equipment during high-speed full-load operation and ensuring no attenuation of forming accuracy during long-term operation. The 25kW high-power main motor provides stable and continuous power output, which can support 24/7 non-stop continuous production of the equipment. The core forming rollers are made of GCr15 bearing steel with overall quenching treatment (HRC57-59°), with super wear resistance. With only basic daily maintenance, the equipment can provide reliable production services for your factory for more than 15 years.
Full specification compatibility, no more assembly mismatch problems
Before leaving the factory, this LD-FD05 fire damper frame machine has passed the compatibility test with all major brands of damper blades on the market. The frame size produced by the standard model fully matches the international general standard blade specifications, and can be directly assembled without secondary grinding, cutting and modification. It perfectly solves the industry pain point that the custom-produced frames cannot match the standard blades, and the batch-produced frames cannot be used universally. At the same time, we support non-standard customization of the frame profile according to your actual product design, to meet the production needs of special specification dampers.
