Requirement review
Confirm part function, material, tolerance, finish, order quantity, annual demand, and target market.
OEM and ODM manufacturing
Custom metal parts manufacturer for OEM sheet metal components.
Black Iron Metal manufactures non-standard sheet metal parts from buyer drawings, with engineering review, process planning, inspection, finishing, and export packing.
For buyers sourcing non-standard metal components
This service is for OEMs, equipment brands, importers, and contract manufacturers that need repeatable custom parts rather than catalog items.
- Custom enclosures, brackets, panels, covers, frames, chassis, cabinets, and welded assemblies.
- Support from drawing review through manufacturing, finishing, inspection, packaging, and shipment coordination.
- Suitable for prototypes, pilot runs, repeat orders, and cost-down sourcing projects.
- RFQ communication focused on specifications, revision control, visible surfaces, and packing details.
Custom parts manufacturing path
Process planning
Select cutting, bending, welding, hardware, finishing, assembly, and packing steps that match the design.
Sample validation
Use sample or pilot production to confirm fit, finish, function, and inspection expectations.
Repeat supply
Move into repeat production with clear revision control and export packing expectations.
OEM supplier-transfer checklist
When moving an existing part from another supplier, the fastest review comes from clear technical history instead of only a target price.
- Current 2D drawings, 3D files, approved revision level, and any marked-up engineering changes.
- Photos or samples showing acceptable finish, visible surfaces, weld quality, hardware, labels, and packing.
- Material grade, thickness, finish standard, critical dimensions, inspection reports, and known fit issues.
- Order quantity, annual demand, delivery schedule, destination market, and current packing method.
- Reason for transfer, such as capacity, quality stability, cost-down sourcing, or supplier consolidation.
Transfer review output
Black Iron Metal can review manufacturability, tooling or fixture needs, inspection focus, finish risks, packing expectations, and sample validation steps before repeat production.
Risk control
Buyer-approved samples, first-article checks, and clear revision references help reduce mismatch when a part is moved from an established supply chain.
NDA, confidentiality, and drawing control
For OEM projects, confidentiality expectations should be confirmed before sensitive drawings, customer names, or application details are shared.
NDA review
Buyer NDA terms can be reviewed before project files are exchanged. Black Iron Metal can also discuss practical confidentiality steps for OEM and ODM sourcing projects.
Controlled files
RFQ files should be labeled with part number, drawing revision, date, material, finish, and any export or customer-specific requirements.
Limited use
Drawings and samples are used for quotation, manufacturability review, sampling, and production planning for the requested project.
Repeat orders and revision control
Repeat custom parts need a stable reference package so each production run follows the approved version.
Approved baseline
Confirm the drawing revision, sample approval status, material, finish, tolerances, and inspection points before production release.
Change requests
Separate design changes from purchasing notes. Updated drawings should replace obsolete files before quotation or production starts.
Order history
For repeat supply, reference prior order numbers, accepted samples, quality notes, packing method, and destination requirements.
Production records
Inspection focus, visible surface requirements, hardware details, and packing instructions should stay linked to the active revision.
Parts and applications

Cabinets, covers, shells, access doors, vented panels, and control housings.
Mounting and support parts
Brackets, plates, channels, frames, fixtures, and welded supports.

Custom metal parts FAQ
What custom metal parts can you manufacture?
We manufacture custom sheet metal enclosures, cabinets, brackets, panels, frames, welded assemblies, and OEM components from buyer drawings.
Can you help with OEM repeat orders?
Yes. The workflow is designed for prototypes, pilot builds, and repeat production after specifications, inspection points, finish, and packing are confirmed.
Do you sign NDAs for custom projects?
NDA handling can be discussed before drawings are shared. Buyers can contact sales to confirm confidentiality needs for OEM and ODM projects.
Can you support a supplier transfer for existing OEM parts?
Yes. Buyers can share the current drawing revision, sample photos, inspection requirements, annual demand, packing method, and known quality issues so the transferred part can be reviewed before quotation and sampling.
How are drawing revisions controlled for repeat orders?
Repeat orders should reference the approved drawing revision, sample status, finish specification, inspection points, and packing requirements. Any change request should be confirmed before production so obsolete drawings are not used.
