CNC laser cutting, bending, welding, machining and coating under one roof — with photos, videos and QC reports for every stage of your order, on demand.
CNC FIBER LASER CUTTING — LIVE
No re-handling between subcontractors. Your drawings go in, finished parts come out — with complete control over quality and lead time.
CNC fiber laser cutting for carbon steel, stainless and aluminum — tight tolerances, burr-free edges, thick-plate beveling up to 25 mm.
Precision press braking with repeatable angles for enclosures, brackets and chassis parts — repeatability you can rely on in volume.
MIG / TIG welding by certified operators — structural frames, assemblies and heavy fabrications with controlled distortion.
Milling, drilling and tapping for machined features and post-weld finishing — critical bores held to ±0.05 mm.
In-house powder coating and liquid painting — RAL colors, surface preparation and consistent film build with coating reports.
Non-standard parts built to your drawings — heavy-duty frames, brackets, housings and assemblies. Send your CAD, we handle the rest.
Every order is tracked in our private portal. At each stage we upload photos, videos and inspection reports — you watch your parts move through the shop.
LIVE EVIDENCE
A selection of custom fabrications demonstrating the tolerance and reporting we hold on structural work. View full case studies →
Our delivery SLA is part of the offer. Quoting, inspection and compensation terms are agreed up front — not discovered later.
STEP / PDF / DXF files with material, quantity and target date. We confirm feasibility and check critical dimensions with you.
A fixed quotation with unit price, lead time, payment terms and the SLA — including the QC and tracking commitments.
Your order enters SUNNAX Trace. Photos, videos and QC results are uploaded at every stage — accessible from your private link.
Final inspection report, packing photos and shipment details uploaded before dispatch. We stay available after delivery for any issue.
We respond to every inquiry within one working day, with a technical review and an honest assessment of feasibility and lead time.

Private portal for active orders
Full-chain fabrication under one roof — laser cutting, bending, welding, machining, surface treatment and assembly. Every process is documented for your order file.
High-speed fiber laser cutting with minimal heat-affected zone and burr-free edges. Sheet blanks, profiles, thick-plate parts and beveled edges for welding preparation — all nested for material yield.
CNC press brakes with back-gauge automation give repeatable angles run after run. Enclosures, brackets, chassis and formed structural members with spring-back compensation programmed per material.
Certified welders for structural and precision assemblies. Multi-pass techniques, jig-and-fixture positioning and symmetric sequencing keep distortion under control on heavy fabrications.
Milling, boring, drilling and tapping for machined features on weldments — critical bores, mounting faces and locating holes held to tight tolerances after stress relief.
Shot blasting, powder coating and liquid painting in-house. Consistent film build, RAL-matched colors and documented surface preparation for outdoor and corrosive environments.
Non-standard parts and sub-assemblies built to your drawings — heavy-duty frames, enclosures, housings, brackets and welded assemblies with hardware fitted.
Each project below shows the customer's requirement, how we built it, and the inspection evidence delivered with the shipment.
A robotic work-cell base must carry a high-speed 6-axis robot. Welding distortion had to be controlled and every unit shipped with UT weld reports and assembly dimensional certificates.
Offshore service demands the highest weld quality and full material traceability (DNV / API style). High volume, tight schedule, and the customer required per-piece process videos.
A machine frame is the accuracy carrier of the whole machine: guide-rail straightness decides final machine precision. The customer required documented stress-relief and rail-face machining data.
Upload STEP / PDF / DXF files with your requirements. We review the design, confirm feasibility and reply with a fixed quotation including lead time, payment terms and our QC / tracking SLA.
