OEM Assembly & Finished Product Manufacturing Support
Send your BOM, drawings, samples and packaging requirements. Feiyu can manufacture custom parts, source standard components, inspect incoming parts, assemble, test and prepare shipment-ready OEM products.
OEM Assembly & Supply Chain Support
NBFEIYU supports OEM customers beyond individual component manufacturing, helping connect sourcing coordination, assembly, inspection and final product preparation under one accountable project workflow.
Beyond Component Manufacturing
- Component sourcing coordination based on BOM requirements
- Incoming checks before storage and assembly
- Assembly support for custom and purchased parts
- Functional review before finished product packaging
- Export-ready packing and delivery coordination
- One project contact for manufacturing and supply-chain follow-up
From Multiple Parts to One Finished Product
Many OEM projects are not just one machining or stamping order. They involve custom metal parts, standard hardware, outsourced custom parts, inspection, storage, assembly fixtures, functional testing, packaging and delivery. NBFEIYU coordinates these steps so your team can reduce supplier-management work.
- Manufacture custom parts in-house
- Source standard parts from BOM
- Coordinate outsourced custom parts
- Inspect parts before assembly
- Prepare fixtures and work instructions
- Test and pack finished assemblies
Why Manage Multiple Suppliers When One Partner Can Handle the Project?
This model is designed for OEM buyers who need fewer supplier handoffs, clearer project ownership and better control before shipment.
| Multi-Supplier Model | NBFEIYU Integrated Model |
|---|---|
| Multiple supplier contacts and separate schedules | One project contact with centralized production planning |
| Separate quality standards and inspection methods | One QC workflow from incoming parts to final packaging |
| Customer manages sourcing, storage and assembly risk | NBFEIYU manages sourcing coordination, warehouse control and assembly readiness |
| More logistics and responsibility gaps | Consolidated packaging, delivery and project ownership |
How We Build Complete OEM Products
The workflow keeps procurement, manufacturing, inspection and assembly connected instead of treating each step as a separate supplier problem.
Custom Components, Standard Parts and Outsourced Parts Managed Together
Instead of splitting these into three long sections, NBFEIYU reviews them together during quotation because they all affect cost, lead time, quality and assembly risk.
Custom Components Manufactured In-House
CNC machined parts, cast metal parts, stamped parts, sheet metal components, welded assemblies, laser cut parts, bent metal parts and surface-treated parts.
Standard Parts Procurement
Fasteners, bearings, springs, bushings, plastic parts, motors, electronics, cables, rubber parts, seals, handles, hinges and packaging accessories.
Outsourced Custom Parts Coordination
Supplier selection, drawing communication, schedule follow-up, incoming inspection, storage control and assembly readiness review.
Incoming QC, Warehouse Control and Assembly Kit Preparation
Parts are checked before they enter storage or assembly. Approved components are stored by project, part number, quantity and assembly schedule to reduce shortages, mix-ups and last-minute quality problems.
- Dimensional and appearance checks
- Surface treatment and packaging checks
- Supplier document review when required
- Project-based storage and part identification
- Inventory control and shortage tracking
- Assembly kit preparation before release
Fixture-Based Assembly and Functional Testing Before Packaging
For repeat OEM production, assembly quality depends on fixtures, clear work instructions, controlled sequence and testing before shipment. Finished assemblies can be 100% tested when required.
- Assembly fixture design
- Positioning fixture preparation
- Work instructions
- Torque control when required
- Mechanical operation test
- Fit and movement test
- Electrical or leak test when applicable
- Final appearance and packaging inspection
Typical OEM Assembly Projects We Support
Best suited for multi-component products where metal part manufacturing, purchased components, inspection and final assembly need to be managed as one project.
Mechanical product assemblies
Metal hardware assemblies
Outdoor equipment assemblies
Automotive accessory assemblies
Industrial equipment sub-assemblies
Bracket and frame assemblies
Private-label OEM products
Semi-finished assemblies
How We Reduce Your Project Risk Before Shipment
Quality control is not left until the final product. NBFEIYU checks the project at supplier, incoming, warehouse, assembly, test and packaging stages.
Supplier and Incoming Control
Supplier quality review, drawing/spec confirmation, incoming inspection and document review before warehousing.
Assembly Process Control
Assembly fixtures, work instructions, operator training, sequence review, torque control and in-process checks when required.
Final Testing and Packaging
Functional testing, final inspection, labeling, protective packaging, carton or wooden crate packing and export shipping marks.
Example: From Components to Finished Assembly
A customer sends drawings and BOM for a product that includes custom metal parts, standard hardware, outsourced components and final retail or export packaging.
- Make custom metal parts
- Purchase standard components
- Coordinate outsourced parts
- Inspect incoming parts
- Store approved components
- Prepare assembly fixtures
- Assemble and test product
- Pack finished goods
Capabilities Connected to Assembly Projects
Assembly projects often need several manufacturing and finishing processes before the final product can be tested and packed.
Upload Your BOM & Drawings for an Assembly Review
Send drawings, BOM, product photos, samples, assembly requirements, testing requirements, packaging requirements and target quantity. NBFEIYU will review how to manufacture, source, inspect, assemble, test and deliver the complete solution.
Assembly & Supply Chain FAQ
Short answers for OEM buyers preparing an assembly or supply-chain RFQ.
Can NBFEIYU provide complete product assembly?
Yes. NBFEIYU can manufacture custom components, source standard parts, coordinate outsourced custom parts, inspect incoming components, assemble finished products, perform functional testing and prepare export-ready packaging.
Can you manufacture some parts in-house and purchase other components?
Yes. Many OEM projects combine in-house CNC machining, stamping, casting, welding or surface treatment with purchased fasteners, bearings, springs, rubber parts, electronics or standard hardware.
Can you source standard parts according to our BOM?
Yes. Send your BOM, drawings, specifications and approved brand requirements. NBFEIYU can source commercially available components and check them before assembly.
How do you control outsourced custom parts?
NBFEIYU manages outsourced custom parts through supplier communication, drawing and specification control, schedule follow-up, incoming inspection, storage control and assembly readiness review.
Do you inspect purchased parts before assembly?
Yes. Purchased parts and externally processed parts are checked before warehousing and assembly according to drawings, samples, BOM requirements or customer quality standards.
Can you prepare assembly fixtures?
Yes. Depending on product structure, production volume and quality requirements, NBFEIYU can prepare positioning fixtures, assembly fixtures, gauges, work instructions and process controls.
Do you test finished products before packaging?
Yes. Finished assemblies can receive functional testing before packaging according to customer requirements, including mechanical operation, fit, torque, load, electrical or leak testing when applicable.
What information should we send for an assembly project?
Please send 2D drawings, 3D CAD files, BOM, material grade, purchased part specifications, samples or photos, assembly requirements, testing requirements, packaging requirements, quantity and annual demand.
