High-Accuracy Automatic HVAC Air Plenum Box & Silencer Roll Forming Machine | 15KW Ductwork Noise Control Equipment LD-SF01

We’ve been making cold roll forming equipment for 30 years, and we know exactly what frustrates HVAC manufacturers the most about making air plenums and silencers. Hand-fabricated units are never perfectly square, they leak air, they don’t deliver consistent noise reduction, and they take hours of skilled labor to make. This Liding LD-SF01 solves all these problems. It turns raw steel coils into perfectly formed plenum box and silencer profiles automatically, with consistent dimensions and airtight seams. No more rework, no more noise complaints, no more wasted labor. It’s the essential addition to your HVAC production line.

lidingWhy choose this machine?

Consistent quality that passes every inspection

Hand-made silencers and plenums always have inconsistent dimensions and leaky seams, which ruins their noise reduction performance. This machine produces every profile exactly the same, every single time. The seams are perfectly tight, and the dimensions are accurate to ±0.3mm, so your units will always deliver the specified noise reduction and pass all inspections.

Cut your labor costs by 70%

Before this machine, you needed 2-3 skilled workers spending hours cutting, bending, and welding each plenum box. Now one unskilled worker can operate this entire line and produce more units in an hour than your team used to make in a day. Your labor costs will drop dramatically overnight.

Built to last for 15+ years

We don’t cut corners on construction. This machine features a heavy-duty steel frame and precision-machined components that are designed to withstand years of continuous use. With only basic maintenance, it will serve your factory reliably for over 15 years.

Customizable for all your needs

Every HVAC project is different, and we get that. We can customize this machine to produce any plenum box or silencer profile you need. Whether you’re making standard residential units or heavy-duty industrial silencers, we can build the perfect machine for you.
