CNC Laser Cutting Service for Sheet Metal
Fulei Metal uses three laser cutting machines, including a newer TRUMPF machine, to prepare enclosure panels, brackets, openings and formed-part blanks from buyer drawings.
Scope
What This Capability Covers
Laser cutting is the start of a larger manufacturing route. Quotation and production planning consider not only the cut profile, but also grain or finish direction where relevant, bend sequence, deburring, protective film, part identification and the features that will later receive hardware or welds.

Manufacturing route
How the Work Is Controlled
- 01
Import and compare controlled drawing files
- 02
Confirm material and cutting-side requirements
- 03
Program nesting and identify high-risk small features
- 04
Cut, separate and deburr parts as the project requires
- 05
Release blanks to bending or inspection with revision identity
Engineering checkpoints
Where OEM Projects Usually Need Clear Decisions
These points are reviewed against the real part and the buyer’s acceptance requirements.
Small features
Slots, tabs and narrow webs are reviewed against the actual material and downstream forming risk.
Heat and flatness
Large open patterns and thin sheets may need a cutting sequence that reduces local heat accumulation.
Edge condition
Burr, dross and sharp-edge expectations should match the part's handling and final assembly.
Downstream fit
Cut features close to bends, welds or hardware are checked as part of the completed component, not in isolation.
Buyer input
What to Include in Your RFQ
Clear project information allows engineering questions, price and timing to be based on the same scope.
- DXF or DWG profile plus controlled PDF drawing
- Exact alloy or steel grade and thickness
- Critical openings and mating interfaces
- Cosmetic side and protective-film requirement
- Quantity, annual demand and next manufacturing step
FAQ
Questions Buyers Ask Before Ordering
What Drawings a CNC Laser Cutting Service Sheet Metal Quote Needs
2D drawings (PDF, DWG or DXF) and 3D models (STEP, IGES or SolidWorks) both help. Please include material grade and thickness, surface finish, quantity, and any critical dimensions or inspection requirements. Where a feature is not specified on the drawing, we raise it in the DFM review instead of assuming a value.
Prototype Before Batch on CNC Laser Cutting Service Sheet Metal
Yes. Prototypes and repeat batches run on the same equipment, so the first article reflects real production conditions. Minimum order quantities are 10 pieces for large parts, 50 for medium parts and 1,000 for small parts, and prototypes are accepted below those levels.
Materials and Finishes for CNC Laser Cutting Service Sheet Metal
SPCC, SECC, Q235, SUS304 stainless steel, aluminium and galvanised steel, generally from 0.5 mm to 18 mm. Finishes include powder coating, zinc plating, galvanising and passivation. We work in sheet metal and CNC processes — castings are outside our scope.
What Paperwork Comes With CNC Laser Cutting Service Sheet Metal?
Dimensional reports taken against your drawing, together with first-article, in-process and outgoing inspection records. Calipers, height gauges and gauges are used for critical dimensions, and coating thickness or salt-spray checks are added where the drawing calls for them.
How small can holes and slots be?
Feature size is limited by material thickness rather than by a fixed number. Features noticeably smaller than the sheet thickness are flagged in the DFM review so we can agree on whether to cut, drill or punch them, and on the dimension that will be inspected.
How do you control heat distortion on thin panels?
Nesting, cut sequence and cutting parameters are set for the material and thickness, and flatness is checked after cutting. When a panel is thin and visible, we agree the acceptable flatness with you before production.
Send your drawings to our engineering team and we will return a DFM review together with the quotation. Request a quote, or see the full range on custom sheet metal fabrication.

Let the Drawing Define the Process and Acceptance Plan
Send the controlled files, quantities and application context. We will identify missing information and prepare a practical basis for quotation.
Trade Terms and Delivery
We quote under the standard Incoterms your logistics team already works with, and build the packing and documentation around the one you choose.
- EXW — you collect from our Ningbo facility and run export clearance through your own forwarder.
- FOB Ningbo — we deliver to the vessel at Ningbo port and handle export clearance.
- CIF — we cover carriage and insurance to your named destination port.
- DDP — we handle carriage, insurance, import clearance and duties through to your door.
Send your destination country, target delivery date and preferred trade term together with the drawing. Request a quotation.
Payment Terms
How a project is paid for is agreed before production starts, and the structure that applies to your order is stated on the quotation and on the order confirmation, so there is no ambiguity later.
- 30% advance payment with the order and the 70% balance before shipment — our standard structure.
- 70% advance payment with the order and the 30% balance before shipment — used for some projects.
- 100% payment in advance before production starts — used for some projects.
If your finance team works to a fixed structure, say so in the first enquiry and we will confirm what applies to your order before you commit. Request a quotation.
Thin Sheet and Thick Plate: What We Cut
Our fibre laser cutting covers 0.5 mm to 18 mm, split into two bands because they behave differently on the machine and in quotation:
- Thin sheet, 0.5 mm to 5 mm — our main volume. Enclosure panels, brackets, covers, chassis plates and repeat blanks. Nesting, pierce sequence and heat input are what hold flatness here. Detail: precision thin sheet metal cutting.
- Thick plate, above 5 mm up to 18 mm. Quoted after the drawing review, because pierce time, edge quality, taper and the downstream bending force decide the process and the price. Structural brackets, machine bases and welded assemblies sit here.
Tell us the thickness and material in the RFQ and we will confirm which band your part falls into. Send your drawings.
Quotation Time
We quote from your drawings. How long that takes depends on what the part asks for:
- Simple parts — quoted within 24 hours. Laser-cut blanks and bent components, supplied with complete 2D or 3D drawings. Mon–Fri, GMT+8.
- Complex assemblies — quoted after the drawing review. Payment kiosks, multi-part welded frames, enclosures with purchased hardware, or anything needing a coating or assembly trial. We confirm a quotation date once the scope is clear.
Production lead time is quoted separately, after drawing review and process confirmation. Send your drawings.
