Laser cutting

Fibre-laser cutting of carbon steel, stainless and aluminium sheet on Han's Laser flatbed machines. Narrow kerf, burr-free edges — most parts skip secondary deburring.

Positioning accuracy±0.03 mm

MaterialsCarbon steel · stainless · Al

Thermal distortionMinimal on thin gauge

EquipmentHan's Laser fibre flatbed

CNC bending

Press brakes with hydraulic crowning and closed-loop laser angle measurement. A material database calculates springback; the first bend is corrected in real time.

Deflection compensationDynamic crowning, full bed

Angle controlLaser measured, closed loop

ProgrammingParametric · 2D/3D simulation

Set-up timeabout −70%

Welding

Three processes chosen by what the part has to do: friction-stir for cold plates, laser for thin-wall precision parts, TIG for stainless and aluminium boxes.

Friction-stir (FSW)Cold plates · leak-tight

LaserHAZ 0.1–0.5 mm · distortion < 0.1 mm

E-coating & powder

Cathodic electro-deposition reaches inside cavities and seams where spray paint fails. Electrostatic powder gives the outer surface its hardness and colour.
