Stage 02 of 10 — In-house
Laser
Cutting Services
Dongji provides laser cutting services on three fiber laser systems from TRUMPF and AMADA, cutting mild steel to 30 mm and stainless and aluminium to 20 mm on sheets up to 3,000 × 1,500 mm. Available as a standalone service, or as the first cutting stage of a full fabrication programme.
In-house production sequence — all ten stages under one roof
Capability
Laser cutting services — what the machines will hold
The reach of our laser cutting services is set by three things: laser power, sheet envelope, and how the material behaves under a focused beam. Mild steel cuts substantially thicker than stainless or aluminium at identical power, because reflectivity and thermal conductivity differ. The figures below are working limits, not headline numbers.
Thick sections run on our high-power machines. Thin-gauge work runs at lower power, where heat input and edge quality matter more than raw speed.
| Parameter | Specification |
|---|---|
| Machines | 3 × fiber laser (TRUMPF, AMADA) |
| Laser power | 3,000 – 30,000 W |
| Maximum sheet size | 3,000 × 1,500 mm |
| Max thickness — mild steel | 30 mm |
| Max thickness — stainless | 20 mm |
| Max thickness — aluminium | 20 mm |
| Machining accuracy | 0.1 mm |
| Cutting speed | 30 m/min at 1 mm |
| Minimum order | 100 pieces |
Accuracy vs. tolerance
0.1 mm is machining accuracy at the cutting head. It is not the finished tolerance of a formed part — once a blank is bent, springback and positioning error both come into play. If your part will be formed after cutting, work to the bending tolerance table rather than to this figure.
Materials
What we cut
Mild steel, stainless steel, galvanised steel, aluminium, copper and acrylic. Across our cutting operations, thickness spans 0.2 mm to 30 mm depending on material.
Typical parts leaving the cutting bed
- Equipment enclosures & housings
- Electrical and industrial cabinets
- Kiosk and self-service terminal bodies
- Vending machine cabinets
- Brackets and structural frames
- Decorative and architectural panels
Sequence
Cutting is where the errors get caught
Laser cutting is the second of ten stages in our custom sheet metal fabrication programme, following design and preceding CNC punching, bending, welding and finishing. Because we cut in-house rather than buying in blanks, a dimensional error surfaces at stage two instead of at assembly.
It also means blank geometry is adjusted for bend allowance before cutting, not corrected afterwards. Most parts we cut are bent, welded and powder coated in the same building.

Questions
Before you send drawings
What is the largest sheet you can cut?
3,000 × 1,500 mm. Parts larger than this are produced as multiple cut sections and joined by welding — with bending capacity to 3,200 mm, oversized assemblies are routine.
How thick can you cut?
Mild steel up to 30 mm. Stainless steel and aluminium up to 20 mm.
What accuracy can you hold?
0.1 mm machining accuracy at the cutting head. If the part is subsequently formed, the governing figure is the bending tolerance, which varies by flange length.
What is your minimum order quantity?
100 pieces. Samples are available at $20–$100 depending on the part.
How quickly can you quote?
Within 24 hours of receiving your drawings. Send material, thickness and finish along with geometry so the quote comes back complete rather than with questions attached.
