Real-world case studies showcasing laser cutting applications across industries. Learn how different materials, designs, and requirements were solved using advanced laser cutting technology.
Introduction
Nothing illustrates the capabilities of laser cutting better than real-world applications. At Fulei Metal, we have completed thousands of projects for clients across Europe, North America, Japan, South Korea, Southeast Asia, and the Middle East. This article presents several case studies.
Application Notes: Electronic Equipment Enclosures
On enclosures cut from thin sheet, the problem is heat rather than power. A 1.0 mm panel heats quickly along a long cut, and if the path runs continuously around the perimeter the panel can distort enough that the folded part no longer closes. The usual answers are to cut heavy and light geometry in separate passes, to spread the cutting order across the nest rather than working through it sequentially, and to leave small tabs holding the part into the sheet until the job is done, so that nothing moves while it is being cut.
Application Notes: Machinery Brackets in Thicker Plate
Brackets cut from 6 to 10 mm plate behave differently from thin sheet in one visible way: the cut edge carries dross if the speed, focus or assist gas pressure is wrong, and dross on a thick edge is difficult to remove without grinding away the edge squareness that the part was designed around. It is a process setting rather than a material problem, and it is found on the test piece at the start of the run. On parts at this thickness the cut edge is also a functional surface – a bracket that bolts flat against another surface needs the cut edge dressed, and that is a cost worth knowing about before the design is frozen.
Application Notes: Decorative and Architectural Panels
Decorative panels are judged on the inside corner of a pattern, which is the hardest place for a laser to leave a clean result: corners slow the machine, heat builds, and the kerf widens slightly at the point where two cuts meet. The result is a corner that is visibly rounder than the design intended. Where the pattern is going to be visible at close range it is worth accepting a small radius in the design and cutting to it consistently rather than demanding a sharp corner that the process cannot deliver. On panels cut from coated or mirrored stock, the protective film stays on through cutting and is removed afterwards, because the film is what protects the face that the customer will see.
Application Notes: Aluminium Heat Sinks
Aluminium behaves differently from steel at the laser in two respects that affect the quote. It reflects more of the beam, which means the machine runs at higher power for the same thickness and needs the right lens protection, and it conducts heat away from the cut far faster, so thin fins can lose the sharp edge that makes a heat sink work. On finned geometry the cutting parameters matter as much as the design: cut too slowly and the fin edge rounds over, cut too fast and the cut does not go through cleanly. Assist gas is normally nitrogen rather than oxygen for aluminium, because an oxygen cut leaves an oxidised edge that is unacceptable on a thermal part.
Application Notes: Medical and Laboratory Equipment Chassis
On equipment that is cleaned and inspected rather than simply assembled, the cut edge matters as much as the dimension. Laser cutting leaves a small burr on the underside and, on stainless, a narrow heat-affected zone at the edge; both have to be dealt with before the part can be considered finished, and the method chosen matters. Grinding removes the burr but leaves abrasive residue embedded in the surface, which is exactly what a cleanliness-critical part must not have. Tumbling, brushing or electrolytic treatment give a cleaner result for the same purpose. On chassis work the practical rule is that deburring and cleaning are process steps with their own cost, not a final wipe-down.
Application Notes: Small Sensor and Mounting Brackets
Small brackets are a nesting and handling problem rather than a cutting problem. At 30 to 60 mm across, a part can be cut in large numbers per sheet, and the cost is dominated by how densely the nest is packed and how the parts are held while they are cut. Parts of this size are normally held in the sheet by small tabs, then broken out and dressed – and the tab position has to be chosen on a face that will not be visible, because the break leaves a witness mark. Where the volume is high enough, a stamped part becomes cheaper than a laser cut one; below that threshold the laser route is more economical and more flexible, and it is worth asking which basis a quotation is given on.
Lessons Learned
Early collaboration enables significant optimizations. Material selection upfront prevents costly changes. Parameter optimization is critical. Quality systems build trust. Integrated capabilities streamline production.
Conclusion
Real-world projects demonstrate that laser cutting, combined with engineering expertise and quality systems, can solve diverse challenges across industries. At Fulei Metal, our experience across thousands of projects enables us to deliver solutions meeting each client specific requirements.
Part Families and the Specifications They Carry
Rather than listing individual projects, it is more useful to describe the part families we cut routinely and the specification patterns that come with each. If your part resembles one of these, the likely requirements below are a good starting point for a conversation.
| Part family | Typical material and thickness | Typical requirements |
|---|---|---|
| Equipment panels and covers | SPCC or SUS304, 1.0 to 2.0 mm | cosmetic edges, fastener pattern accuracy, usually powder coated |
| Mounting brackets | SPCC or SUS304, 2.0 to 4.0 mm | hole pattern positional accuracy, often formed afterwards |
| Enclosure doors and frames | SUS304 or SUS316, 1.5 to 3.0 mm | flatness, sealing surfaces that must meet an IP rating |
| Perforated ventilation panels | SPCC or aluminium, 0.8 to 1.5 mm | dense hole arrays, burr-free edges |
| Machine guards | SPCC, 2.0 to 3.0 mm | safety edge treatment, usually welded then coated |
| Cable management plates | SECC or aluminium, 1.0 to 2.0 mm | clean edges on slots and cut-outs |
We describe families rather than tell project stories deliberately. A specification tells you something you can act on; whether we have made an almost identical part before is a question best answered directly, and answering it takes one drawing review rather than a guess either way.
Frequently Asked Questions
Have you made a part like ours before?
Send the drawing and we will tell you honestly. Experience with a family is a good indicator, but claiming specific projects we cannot substantiate helps nobody.
Which of these families is most common for export customers?
Equipment panels, brackets and enclosure parts dominate. Ventilation panels and cable management plates appear regularly alongside them in larger assemblies.
What should we include with a first enquiry?
A dimensional drawing with material and thickness, quantity, surface finish requirement, and which dimensions matter. Everything else can follow.
Questions about a specific part are usually faster to answer against the drawing — send it through the route below.
Before you send the RFQ. Reference full fabrication capability first if this part is still at drawing stage — most cost drivers are decided there. For anything already specified, cutting capability is where to send it. Related: product case library and DFM review.
