DFM Design Advice
1/ Keep holes away from edgesPlace holes at least 2× material thickness from any edge to prevent thermal blowout and deformation.
2/ Plan for bends after cuttingKeep cut features at least 2.5× thickness plus the bend radius away from bend lines to avoid oval stretching.
3/ Use nitrogen-cut edges for coatingRequest nitrogen assist on stainless steel and aluminum for an oxide-free edge that welds and powder coats cleanly.
Laser Cutting MaterialsOur fiber lasers cut carbon steel, stainless steel, aluminum, copper and brass across standard thickness gauges.

Why Sango for Laser Cutting

Sango runs fiber lasers up to 12 kW on sheets up to 3000 × 1500 mm. Automatic nesting places parts tightly on each sheet, minimizing scrap material and lowering per-part production cost.

A laser cut is only as good as the file behind it. Our engineers check every DXF for open contours, kerf allowance and hole-to-edge spacing before cutting, ensuring fit on the first try.

What is Laser Cutting?

Laser cutting is a CNC-controlled process using a high-power focused fiber laser beam to melt and vaporize metal along a programmed path. Pure assist gas (oxygen or nitrogen) expels the molten material, leaving a narrow kerf and clean edge without mechanical tool wear.

Pros and Cons of Laser Cutting

✓ Advantages of Laser Cutting

High Precision & Clean Edges

Holds ±0.1 mm with a narrow kerf, so fine slots, small holes and sharp corners need little or no rework.

No Tooling Cost

The laser follows your CAD file directly. Design changes cost nothing, making it ideal for fast prototypes.

Fast & Material-Efficient

Cuts thin sheet at high speed, and automatic tight nesting utilizes maximum material from every sheet.

⚠ Considerations & Limitations

!
Thickness Limits

Optimal below 20 mm steel and 12 mm aluminum. Thicker plate is better suited to waterjet or plasma cutting.

!
Heat-Affected Zone

A narrow heat-affected zone forms on steel, and oxygen cutting leaves an oxide layer that may need cleaning.

!
Reflective Metal Limits

Copper and brass reflect laser energy, capping practical cut thickness at about 5 mm.
