Segment‑oriented Industry Solutions
Air Ducts & Ventilation Frames
Industry Pain Points
Air ducts and ventilation frames are mostly made of thin galvanized steel. Traditional shearing or plasma cutting can cause edge deformation and damage the zinc coating, leading to rust. The assembly of large ducts requires precise flanges and connection holes. Manual layout and cutting are slow, resulting in poor airtightness and high material waste.
- Mechanical cutting damages the galvanized coating, causing corrosion
- Thin plates easily warp and deform during traditional cutting
- Manual marking for flange holes leads to poor alignment and air leakage
- Low efficiency for large-volume duct fabrication
Our Laser Solution
Fiber laser cutting offers non-contact processing for thin galvanized sheets, perfectly protecting the coating and avoiding deformation. It cuts complex duct intersections, flange profiles, and dense bolt holes in one pass. The precise edges ensure perfect fit-up for automated TDF flange forming or welding, significantly improving airtightness.
- Non-contact cutting preserves the anti-corrosion galvanized layer
- Zero deformation for thin duct sheets
- High-precision flange holes guarantee airtight assembly
- Fast cutting speed drastically improves duct fabrication efficiency
HVAC Chassis & Casings
Industry Pain Points
HVAC chassis and casings require high aesthetic quality and structural integrity. They often feature complex cutouts for pipes, dampers, and electrical components. Traditional punching requires expensive dies for every new model. The edges must be clean to ensure a perfect finish after powder coating or painting.
- High mold cost for custom chassis designs
- Burrs and dross require extensive manual grinding
- Mechanical punching causes panel distortion

Our Laser Solution
Fiber laser cutting is a mould-free solution for HVAC casings. It smoothly cuts complex pipe passages, mounting holes, and access doors. The non-contact process prevents mechanical stress and deformation. Clean, burr-free edges are ready for direct bending, welding, and powder coating, enhancing the final product's appearance.
- Mould-free processing for customized and varied chassis designs
- Non-contact cutting prevents panel warping and denting
- Clean, burr-free edges reduce post-processing costs
- Fast setup for instant production switching
Heat Exchanger & Coil Parts
Industry Pain Points
Heat exchangers and coils require tube sheets and end plates with dense, highly precise hole arrays. The holes must perfectly fit the copper or aluminum tubes to ensure a tight seal. Traditional multi-spindle drilling is slow, suffers from tool wear, and can produce burrs that affect fluid flow and brazing.
- Slow drilling speed for dense tube holes
- Tool wear leads to hole diameter inconsistency
- Burrs interfere with tube insertion and brazing quality
- High risk of accumulated tolerance across large plates
Our Laser Solution
High-power fiber laser quickly drills dense tube-hole arrays with exceptional precision and consistency. Zero tool wear ensures every hole is perfectly sized. The non-contact process produces clean, burr-free holes, guaranteeing smooth tube insertion and excellent brazing/welding quality for optimal heat transfer efficiency.
- High-speed drilling of dense hole arrays
- Zero tool wear ensures consistent hole diameters
- Burr-free edges for perfect tube fitting and brazing
- Perfect hole positioning across large plates
Compressor & Motor Brackets
Industry Pain Points
Compressors and motors are heavy, high-vibration components. Their mounting brackets must be extremely robust and precisely cut to ensure perfect alignment during assembly. Traditional sawing and drilling create stress points and burrs, which can lead to vibration noise or structural failure over time.
- Multi-step machining causes hole misalignment
- Mechanical cutting introduces internal stress
- Thick bracket materials slow down traditional processes
- Burrs affect the tight fit of rubber vibration dampers
Our Laser Solution
High-power fiber laser cleanly cuts thick metal brackets without inducing mechanical stress. Complex mounting profiles and bolt holes are finished in a single pass with perfect alignment. The clean, smooth edges ensure a perfect fit for vibration-damping rubber mounts, improving the overall stability and lifespan of the HVAC unit.

- Smooth edges for precise fitting of vibration dampers
Pipe Connectors & Flanges
Industry Pain Points
HVAC systems rely on extensive piping for refrigerants and water. The pipe connectors, flanges, and support rings must have perfect concentricity and precise bolt holes to prevent leakage. Traditional turning and drilling are multi-step processes that easily cause eccentricity and alignment issues.
- Accumulated tolerance in bolt-hole drilling
- Difficulty in achieving perfect concentricity
