Start with the flat profile.
Plan the finished edge.
Laser cutting produces the blank that everything else depends on. We align material, cut geometry, edge treatment and later operations around the drawing.
What the service covers
- Detailed profiles, mounting holes, slots and cutouts
- Deburring and oxide requirements identified before production
- Flat parts or blanks prepared for bending, finishing and assembly
Cut features you can recognize.
From an individual mounting plate to repeated blanks, the important details are in the holes, cutouts and functional edges.
Flat profiles & mounting plates
Hole patterns, contour details and edges that locate the next component.
Repeat cut blanks
A consistent profile, burr direction and surface-protection requirement.
Cutouts before forming
Plan the cut geometry and the hole relationships across the later bend.
Frames with functional openings
Control the opening, mounting interfaces and the finish on visible faces.
Quote the profile, edge and final finish.
Send the flat geometry, material, thickness and quantities. Mark critical holes and the cut-edge requirements so the quote covers the part you will use.
CAD + material + thickness + quantityThickness, envelope and tolerance.
The details that decide the route.
Use material-specific values to assess a flat part, then mark the cut features that matter for fit. Sheet format is not automatically the usable part envelope.
| Material | Sheet thickness | Sheet format | Specify for the quote |
|---|---|---|---|
| Aluminum | 1–6 mm | 3000 × 1500 mm | Alloy and temper, cosmetic face and post-cut forming |
| Brass | Up to 6 mm | 3000 × 1500 mm | Exact grade, surface condition and reflectivity |
| Stainless steel | 0.5–16 mm | 6000 × 1500 mm | Grade, thickness, oxide / burr acceptance and finish |
| Carbon & alloy steel | Up to 20 mm | 6000 × 1500 mm | Grade, thickness, edge condition and later coating |
±0.05–0.20 mmTypical linear tolerance
±0.05–0.10 mmTypical hole-diameter tolerance
Identify critical holes, profiles and their datums. Tight features may need a secondary operation rather than a blanket cut tolerance.
* Material, thickness, length, geometry and final condition affect these ranges and typical targets. Drawing-specific tolerances and the usable part envelope are confirmed in the quotation.
Drawing and execution standards
Make acceptance measurable: identify the standard, edition, class and the features it controls in the order documents.
| Requirement | Applicable standard | How it enters the order |
|---|---|---|
| General linear & angular dimensions | ISO 2768-1 | Select the tolerance class and applicable edition on the drawing. Individually toleranced features remain explicit. |
| Thermal cut-edge quality | ISO 9013 | Agree the cut-quality class and evaluation conditions for the material and thickness. Specify incoming-sheet flatness separately. |
| Geometrical specification | ISO 22081 | Define the general geometrical requirement, datum system and applicable features. Specify numeric controls separately where function requires them. |
| Material purchasing specification | ASTM B209/B209M · ASTM A480/A480M | Aluminum sheet/plate and stainless sheet/strip requirements respectively. State alloy, temper, product form and the required document. |
The standard, edition and class stated in the accepted drawing and order define the requirements. The agreed inspection plan establishes how the finished part is checked.
Design the profile. Protect the function.
Review feature size, remaining material and the condition of the cut edge together. A small drawing change can simplify the route without changing how the part works.
Small holes and narrow slots
Feature size must be reviewed against thickness, alloy and edge requirements. If a hole controls a fit, identify its final diameter and position tolerance; it may need drilling, reaming or another agreed finishing operation.
Narrow webs and long thin features
Closely spaced cuts leave material that can heat, distort or become difficult to handle. Review the remaining web, unsupported length and the function of thin tabs before finalizing the layout.
Kerf, corners and shared contours
Supply nominal finished geometry and identify special corner requirements. Cutting-path compensation and nesting belong to the agreed process plan. Avoid duplicate lines or overlapping contours in a supplied cutting file.
Heat, flatness and released stress
Large cutouts and slender profiles can move as material is separated. State the free-state or supported flatness requirement, cosmetic restrictions and any need for additional flattening or inspection.
Burr direction and oxide condition
Mark handling edges, mating surfaces and coating requirements. Specify any permitted burr or edge break and whether a cut-edge oxide is acceptable. A visually clean edge does not establish suitability for welding or electrical contact.
Parts that will be bent
Provide the formed model and a controlled drawing. Identify grain direction, bend lines and critical dimensions after forming. Confirm the flat pattern with the manufacturing route so bend allowance and tooling assumptions stay consistent.
A hole pattern or cut edge controls the fit?
Show the functional dimensions, edge condition and final finish. We can scope the cutting and secondary operations together.
CAD + material + thickness + quantityChoose the grade for the whole route.
Cutting suitability is only part of material selection. Consider the bend, contact surface, corrosion exposure and final finish before releasing the drawing.
| Material | Grade or condition to identify | Manufacturing check |
|---|---|---|
| Aluminum | Exact alloy and temper, for example 5052-H32 or 6061-T6. | Do not treat the grades as interchangeable. Review forming radius, grain direction and final anodized appearance where relevant. |
| Stainless steel | Grade such as 304 or 316L, thickness and surface designation. | Specify cosmetic faces, grain direction and whether cut-edge discoloration or oxide removal is acceptable. |
| Carbon steel | Specified sheet grade; hot-rolled, pickled or cold-rolled condition. | Surface scale, flatness and cleaning requirements affect coating preparation and appearance. |
| Copper and brass | Exact alloy and sheet condition, such as C110 copper or C260 brass. | Review reflective-material cutting, edge condition and contact or decorative requirements for the actual part. |
| Coated and spring sheet | Base grade, coating designation or hardened condition. | Consider coating damage at the cut, heat-affected edges and any subsequent forming or treatment. |
Specify the exact grade, thickness and supply condition. Material availability and the cutting route are confirmed in the quotation.
The edge and finish belong in the quote.
Specify the result you need on the finished part, including visible faces, contact areas and dimensions that apply after treatment.
Cosmetic surfaces
Identify brushed direction, visible faces, allowable handling marks and reference samples. Appearance needs a separate acceptance description.
Protective treatments
Review powder coating, anodizing or suitable plating with the material. Specify masking, contact points and final dimensions after treatment.
Review surface finishing Continue from cutting to bending
Define what makes the part acceptable.
Make the drawing, revision and agreed inspection scope the reference for both quotation and delivery.
Control the profile, hole and cut edge.
Connect the controlled drawing to an agreed inspection plan. Identify the features that govern function and the records required with the finished parts.
- Critical profiles, hole diameters and locating datums
- Cut-edge burr, oxide and perpendicularity requirements
- Material documentation and the incoming sheet condition
- Final acceptance after deburring, coating or later forming

Before you send the profile.
Practical answers for laser-cut sheet metal RFQs.
Which files should I provide?
Send the flat profile and a controlled drawing with units, material and thickness. Include a formed model if the part will be bent. DXF or DWG geometry can help describe the cutting outline; confirm accepted formats and upload limits on the quotation form.
Can every hole be cut to its final tolerance?
No single hole rule covers every material and thickness. Identify functional fits and hole-position requirements. Small or tightly controlled features may require an agreed secondary operation.
What thickness and part size can you cut?
Send the exact alloy, thickness and part envelope. Usable capacity depends on the material, geometry and required edge quality, and is confirmed during quotation rather than inferred from a maximum sheet-loading size.
Will the parts arrive with burr-free edges?
Specify the required edge condition and acceptable edge break. Cutting and deburring are separate process decisions; they should be included explicitly in the agreed scope.
Can laser cutting be combined with bending?
Yes, cutting and bending can be reviewed as one manufacturing route. Share the final formed geometry, bend requirements and critical dimensions so the flat pattern and forming assumptions can be checked together.
When does stamping become worth considering?
Repeat demand, geometry stability and the tooling investment determine the comparison. Request quantity breaks and review metal stamping when a repeat production program may justify dedicated tooling.
How is lead time confirmed?
Material sourcing, nesting quantity, cutting, deburring, secondary operations, finish and inspection all affect the schedule. Share the required date and any staged-delivery needs; quotation response and manufacturing lead time are separate.
