01 / What We Fabricate
From Fabricated Parts to Assembly-Ready Kits
Many OEM buyers searching for sheet metal assembly services do not want only loose fabricated parts. They need panels, brackets, covers, weldments, hinges, inserts, gaskets and hardware delivered as controlled mechanical assemblies that reduce final-line work and incoming inspection risk.
Hardware-Installed Parts
PEM nuts, studs, standoffs, hinges, latches, handles and threaded inserts installed before shipment.
Sealed and Gasketed Assemblies
Doors, covers, access panels and enclosure parts with gasket, seal and latch fit checked.
Production Kits
Revision-controlled assemblies packed by model, line station or installation sequence.
Our scope: mechanical sheet metal assemblies and hardware-ready kits
The OEM owns system-level electrical, software, safety, performance and compliance validation. DRAmetal manufactures the sheet metal parts and specified mechanical assemblies according to the released drawings, BOM and assembly instructions.

03 / Technical Capabilities
Typical OEM Sheet Metal Assembly Specification
| Materials | Cold-rolled steel, galvanized steel, stainless steel, aluminum and mixed-material sheet metal assemblies |
|---|---|
| Processes | Laser cutting, punching, bending, welding, hardware insertion, surface finishing, gasket installation and mechanical assembly |
| Assembly features | PEM hardware, hinges, latches, handles, gaskets, brackets, covers, access panels, frame parts and mounting plates |
| Quality controls | First article, hardware presence check, fit check, critical interface inspection, finish review and packout verification |
| Documentation | Drawing revision, BOM, inspection record, hardware list, approved deviation and packaging photo when required |
| Delivery format | Loose parts, subassemblies, installation kits, line-side packs or export-protected finished assemblies |
| Characteristic-to-report matrix | Connect each acceptance characteristic to the released drawing, balloon identifier, tolerance, inspection state, method and required report field. Identify repeated features individually where needed. |
| Measurement and fixture review | Select tactile, optical or functional checks by access and uncertainty. Agree datum establishment, support, restraint and reload repeatability before interpreting a close-to-limit result. |
| Change and first-article review | Review drawing, hardware, process, tooling and inspection changes for their effect on the accepted baseline. Confirm customer-required full or partial first-article scope before the affected release. |
| Split-lot delivery records | Keep order release, production lot and shipment identities distinct. Link supplied revisions, inspected quantities, approved deviations and report versions to each delivered kit. |
| Retained references and gauges | Identify the approved master, mating reference or limit gauge and its intended use. Define storage, condition checks and reapproval after replacement or revision. |
04 / Manufacturing Process
From BOM Review to Assembly-Ready Packout
01
Assembly Boundary Review
Confirm what DRAmetal assembles and what the OEM keeps for final electrical, pneumatic or system integration.
02
DFM and BOM Check
Review parts, hardware, finish sequence, gasket locations, assembly access and inspection points.
03
Fabrication
Cut, form, weld and finish the sheet metal parts that feed the assembly cell.
04
Hardware and Gasket Install
Install inserts, hinges, latches, studs, seals and other drawing-defined hardware.
05
Assembly Inspection
Check fit, hardware presence, critical interfaces, finish quality and revision alignment.
06
Kitted Delivery
Pack assemblies by model, station, revision or installation sequence to reduce OEM line work.
05 / Why It Matters
Why Sheet Metal Assembly Needs More Than Parts Supply
Assembly work shifts risk from the OEM line to the fabrication supplier. The supplier must control BOM, hardware, finish sequence, tolerance stack-up and packaging.
Tolerance Stack-Up
Small part deviations can become door fit, hinge or bracket alignment problems after assembly.
Hardware Errors
Missing or wrong inserts, studs and latches create avoidable production-line stops.
Finish Sequence
Some parts need hardware before coating; others need coating before gasket or final assembly.
Line-Side Packout
Kitted delivery reduces receiving checks, picking errors and final assembly time at the OEM.
Evidence That Matches the Delivered Kit
A report should identify which drawing revision and production lot it covers, what was inspected and how exceptions were released. Split shipments need their own traceable link to that evidence.
Measurement Agreement Before Production
A passing sample is useful only when the buyer and supplier agree on the measurement condition and acceptance rule. Resolve fixture, datum and method differences before using results to adjust production.

The Customer Challenge
Frequent drawing changes led to old-revision parts at assembly, unclear batch identification obstructed traceability, and inconsistent inspection reports delayed customer acceptance.

09 / FAQ
OEM Sheet Metal Assemblies FAQ
What assembly work can DRAmetal perform?
We can install PEM hardware, studs, hinges, latches, handles, gaskets, brackets, covers, panels and other drawing-defined mechanical components.
Can you build complete electrical control panels?
We normally supply the mechanical sheet metal assembly. Electrical wiring, controls, software and system validation remain with the OEM or integrator unless separately defined.
Can assemblies be packed by line station?
Yes. Finished assemblies can be grouped by product model, line station, drawing revision or installation sequence.
How do you prevent missing hardware?
Hardware lists, assembly checks and final inspection can be tied to the BOM and drawing revision. Any full-presence check must be defined in the agreed inspection plan.
What should a split-delivery inspection report identify?
Agree the part and drawing revision, order release, production lot, inspected quantity, characteristic identifiers, results and approval status. Link each shipment to the applicable report and identify any accepted deviation without treating it as a permanent drawing change.
Does every change require a complete new first article?
The customer requirement and change impact determine the review scope. Assess the affected characteristics and retained baseline, then agree whether a full or partial first article is required. A new material, fixture, process route or inspection program may need review even when the part number is unchanged.
