Advanced Workshop Facilities

Laser Cutting Machine

Rotary Flanging Machine

Rotary Flanging Machine

Two laser cutters (12,000W & 6,000W) handle materials up to 60mm and 8mm respectively. Featuring advanced lasers, they ensure fast, precise cutting with smooth edges requiring no post-processing

Rotary Flanging Machine

Rotary Flanging Machine

Rotary Flanging Machine

Auto-flanging machine forms integral flanges on air dampers with uniform body-flange thickness, reducing 4+ production steps per unit while enabling reducer/diameter-transition fabrication.

Robotic Welders

Rotary Flanging Machine

Hydraulic Modeling Machine

Robotic welders meet NDT standards with near-zero defects (<1%), handle complex geometries 4-5x faster than manual welding, and enable 1 operator to control 3-4 units simultaneously.

Hydraulic Modeling Machine

Hydraulic Modeling Machine

Hydraulic Modeling Machine

This 2500t hydraulic press handles sheet metal straightening, thin-plate die forming, and pressure tests for dampers (≤4m). It also presses corrugated bellows for pipe compensators.

Sand Blasting Machine

Hydraulic Modeling Machine

Sand Blasting Machine

Covers 3000x3000mm damper sandblasting work.
Adjustable speed, depth and thickness, micro processing detail which directly affects the adhesion of the paint and achieves better corrosion protection.

Spray Painting Room
