2. Model numbers.
Customer's model numbering system. OEM customer assigns model numbers to blowers.
3. Colors and finishes.
Customer's specified paint color and finish. Custom color matching available.
4. Documentation.
Custom manuals with customer's branding. Test reports with customer's header. Installation guides with customer's information.
5. Packaging.
Custom packaging with customer's branding. Special crating and shipping requirements.
6. Serial numbers.
Custom serial number format. Batch traceability for OEM orders.
Private labeling requirements:
Minimum order quantity: Typically 5–10 units (depends on manufacturer)
Lead time: 4–8 weeks for standard; 8–12 weeks for custom
Artwork and branding: Customer provides logo and specifications
Setup cost: May apply for new brand nameplates and documentation
Quality Control for OEM
Quality control requirements for OEM orders:
1. Consistent specifications.
All units in an OEM order must be identical. Same components, same assembly, same testing. Specification control is critical.
2. Factory Acceptance Testing (FAT).
Each unit tested to the same standard. Flow, pressure, power, temperature, and vibration verified. Test reports provided with each unit.
3. Batch traceability.
Each unit traceable to components and production batch. Serial numbers track production history.
4. Inspection reports.
In-process inspection reports available. Material certificates for critical components. Dimensional inspection for machined parts.
5. Third-party inspection.
OEM customer may request third-party inspection. Independent verification of quality.
What to specify for OEM quality:
Testing requirements (FAT for each unit or sampling)
Documentation requirements (test reports, certificates)
Inspection points (in-process, final)
Acceptance criteria (vibration limits, temperature limits)
Non-conformance procedure (disposition, corrective action)
OEM Partnership Considerations
What to look for in an OEM partner:
1. Engineering capability.
Does the manufacturer have in-house engineering? Can they do custom designs? Zhanggu and other established manufacturers have engineering teams.
2. Quality control.
ISO 9001 certification. Documented quality procedures. Test equipment and facilities. Non-conformance tracking.
3. Production capacity.
Can they handle OEM order quantities? Flexible production for small and large orders. Dedicated OEM production line.
4. Lead time.
Consistent lead times for OEM orders. Expedite options available. Raw material inventory.
5. Confidentiality.
Protects customer's design and specifications. Non-disclosure agreements. Secure documentation.
6. Support.
Technical support for OEM customers. Training for sales and service. Troubleshooting assistance.
7. Pricing.
Competitive OEM pricing. Volume discounts. Payment terms.
What to discuss before partnership:
Minimum order quantity
Lead time for standard and custom orders
Pricing structure and volume discounts
Warranty terms
Spare parts availability and pricing
Technical support and training
Confidentiality and non-compete
Termination clauses
Common Mistakes
1. Choosing the wrong OEM partner.
Manufacturer with poor quality control causes problems. Manufacturer with limited engineering cannot support custom needs. Evaluate thoroughly before partnership.
2. Not specifying quality requirements.
Quality expectations not documented. Units delivered with inconsistent quality. Specify testing, inspection, and acceptance criteria.
3. Overlooking lead time.
OEM orders take longer than standard orders. Custom components require additional lead time. Plan ahead.
4. No spare parts plan.
OEM parts may only be available from the manufacturer. OEM customer may not stock parts. Plan spare parts with the OEM order.
5. Insufficient technical support.
OEM customer may not have technical capability to support end users. Manufacturer must provide support. Training is essential.
6. Confidentiality issues.
Customer specifications shared with competitors. Non-disclosure agreements required. Confidentiality is critical.
7. Pricing changes.
OEM pricing may change after partnership starts. Long-term pricing agreements protect against increases.
