Capabilities

Every step of the fabrication process under one roof - and one contract. Combine operations in a single setup to cut cycle time and eliminate the handling errors that come with juggling multiple vendors.


OEL fiber laser cutting capability

Laser Cutting and Punching

Fiber and CO2 laser cutting on Japanese-built Amada-class systems for sheet and tube, plus CNC punching for high- speed feature work. Combined laser-and-punch in one setup eliminates re-registration errors.

OEL CNC bending capability

CNC Bending

Amada HDS and HG series press brakes driven by bending- simulation software. A deep in-house tooling library covers typical V-die, U-die, hemming and offset setups with minimal setup time.

OEL welding capability

Welding

Gas Metal Arc Welding (GMAW / MIG), Flux-Cored Arc Welding (FCAW) and Gas Tungsten Arc Welding (GTAW / TIG) on certified equipment. Welds are inspected and finished to match the surrounding surface quality.

OEL surface finishing capability

Surface Finishing

Powder coat (full RAL palette), PVD, galvanizing, electroplating, brushing, sanding, polishing and screen printing - all in-house so finishing cycles fold directly into the fabrication lead time.

OEL mechanical assembly capability

Mechanical Assembly

Full mechanical sub-assembly and final assembly - press- fit inserts, rivet nuts, bonded gaskets, wire harnesses and torqued fasteners. Parts arrive inspected, packaged and ready to install.

OEL DFM design for manufacturability

End-to-End DFM

Before a single sheet is cut we run a Design-for- Manufacturability review: bend allowance, flange clearances, weld accessibility, tooling fit, fastener choices. Cost-down opportunities flagged before quote.

Built on proven equipment

Japanese-built production systems for fabrication-grade precision.

From DFM to packaged assembly

A seven-stage workflow designed so each step catches issues before they become scrap. You send a CAD; you receive an inspected, finished and packed product.


01
DFM review

We validate your CAD against bend allowances, minimum flange lengths, hole-to-edge spacing, weld access and finishing compatibility. Cost-down suggestions flagged before a quote issues.

02
Nesting and cutting

Parts are nested for yield, then cut on fiber or CO2 laser (sheet and tube). Thicker plate routes to CNC plasma; precision sheet work runs on the Amada laser-punch combo.

03
Forming

Press-brake bending with simulation software to confirm final geometry. Roll-forming for cylindrical sections. In-house die library means most setups skip external tooling lead times.

04
Welding

GMAW, FCAW or GTAW per the drawing. Welds are visually inspected, then ground and finished to match the surrounding surface before they hit the finishing line.

05
Finishing

Powder coat, PVD, anodize, galvanize, electroplate, screen print or brushed mechanical finish. Parts are masked and handled to preserve critical features.

06
Assembly

Mechanical assembly, fastening, harnesses, gaskets, sub-assembly integration. Optional kitting for downstream lines.

07
Inspection and packaging

Documented QC inspection, secure NDA-compliant packaging and the Incoterm of your choice - Ex Works, FCA, FOB, CIF, DDP, DDU.

Frequently asked


Primary: AutoCAD DWG and DXF for 2D; SolidWorks, STEP (.stp) and IGES (.igs) for 3D. We can work from clean sketches or a reference sample if drawings don't exist yet - additional CAD drafting charges may apply.

From a single custom piece through 10,000+ unit production runs. We routinely combine high-complexity low-volume work with high-volume cost savings on the same setup, so the unit price scales sensibly as your quantity grows.

Yes. We sign mutual NDAs at the start of every sensitive engagement, use secure email channels for drawing transfer, and operate an electronic drawing control system that tracks versions, access and release.

Thin-gauge sheet from 0.3 mm up through 20 mm plate. Maximum sheet length of 3,000 mm on the laser / punch. Thicker material beyond 20 mm is routed to CNC plasma or oxy-fuel cutting if the part calls for it.

Yes - that's the point of running everything under one roof. Press-fit inserts, rivet nuts, bonded gaskets, wire harnesses, torqued fasteners, label application and sub-assembly integration are all standard. Kitting for downstream lines is also available.

Welds are ground and blended to match surrounding surfaces before finishing. Critical surfaces are masked during powder coat or plating. Brushed and polished mechanical finishes run on dedicated lines so that particulate from prior operations doesn't contaminate the grain direction.
