When discussing custom magnet systems, one question always comes early:
👉 “What is the lead time?”
The answer is often given as:
- 6–8 weeks
- 8–12 weeks
- Or longer for complex systems
But this number is only the surface.
In reality:
👉 Lead time is not a fixed value—it is the result of multiple project stages.
Understanding these stages helps:
- Set realistic expectations
- Avoid delays
- Improve project efficiency
1. Lead Time Is a Process, Not a Number
Custom magnet systems are engineering projects.
They involve:
- Design
- Procurement
- Manufacturing
- Testing
- Documentation
According to Wikipedia:
https://en.wikipedia.org/wiki/Engineering_design_process
Engineering projects progress through defined stages, each contributing to total lead time.
👉 Skipping clarity in any stage introduces delays later
2. Design Freeze: The Most Critical Milestone
What Is Design Freeze
- Final confirmation of all technical parameters
- No further changes to system configuration
Why It Matters
👉 Production cannot begin without design freeze
Common Delay Source
- Ongoing requirement changes
- Incomplete technical inputs
- Late-stage modifications
👉 Every design change resets part of the timeline
3. Component Procurement: The Hidden Bottleneck
After design freeze, key components must be sourced.
Typical Components
- Copper conductors
- Magnetic materials
- Power electronics
- Cooling systems
Risk Factors
- Supplier lead times
- Availability fluctuations
- Custom vs standard parts
👉 A single long-lead component can define the entire schedule
4. Manufacturing and Assembly
Includes
- Coil winding
- Mechanical fabrication
- System assembly
What Affects Duration
- System size
- Precision requirements
- Customization level
👉 More customization → longer build time
5. Testing and Validation (FAT)
Before shipment, systems undergo Factory Acceptance Testing (FAT).
Typical Tests
- Electrical performance
- Current and voltage verification
- Basic magnetic field validation
- Safety checks
According to IEEE practices, validation is essential to ensure system reliability.
Time Impact
- More complex systems require more extensive testing
- Re-testing may be needed if adjustments are required
6. Documentation and Reporting
Often underestimated, documentation is a real time driver.
Includes
- Test reports
- Calibration data
- User manuals
- Interface documentation
Why It Takes Time
- Data collection and verification
- Formatting and review
- Compliance requirements
👉 High-quality documentation adds time—but reduces future issues
7. Packing and Shipping Preparation
Before delivery:
- Systems are disassembled (if required)
- Packed for transport
- Prepared for export
Challenges
- Large system packaging
- Protection against damage
- Compliance with shipping regulations
8. What Causes Lead Time Variability
Lead time varies due to:
1. Requirement Clarity
- Clear requirements → faster execution
- Unclear inputs → delays
2. Customization Level
- Standard systems → shorter lead time
- Full custom systems → longer development
3. Supply Chain Conditions
- Component availability
- Global logistics
4. Validation Scope
- Basic testing vs extended verification
9. How Customers Can Reduce Lead Time
Provide Complete Technical Information Early
- Field requirements
- Volume and geometry
- Application details
Avoid Late Changes
- Finalize specifications before production
Align on Testing Scope
- Define FAT and documentation requirements early
👉 The more defined the project, the shorter the timeline

Key Takeaways
- Lead time is driven by multiple project stages
- Design freeze is the most critical milestone
- Component procurement can create bottlenecks
- Manufacturing time depends on customization level
- Testing and documentation add necessary time
- Clear requirements reduce delays
Lead time is not just a schedule.
👉 It is the result of decisions made throughout the project.
