How we work
From spec to shipment in four steps
A transparent, milestone-driven process that keeps your project on schedule.
- Requirements
- Share your drawings, specs, or a physical sample. Our engineers translate them into a manufacturable magnetic design.
- Design & Sampling
- We validate electrical parameters and deliver prototypes in as fast as 7 days for your approval.
- Production
- Scaled production on automated winding lines under ISO9001 process control.
- QC & Delivery
- 100% pre-shipment testing, then export to 80+ countries with reliable logistics.
Customize from a design or from a sample
Whether you have a finished spec or a working part in hand, we make it easy to get the exact component you need.
Design-based
Engineer from your drawings, schematics, or electrical specs
Simulation and parameter validation before tooling
Rapid 7-day prototype iteration
Sample-based
Reverse-engineer your physical sample to exact parameters
Material and core matching for equivalent performance
Drop-in replacement with full documentation
Tested before it ships, every time
Reliability in demanding industrial environments is non-negotiable. Every unit is verified against its electrical parameters before leaving our factory.
- 100% pre-shipment testing on every unit
- ISO9001:2015 quality management system
- Dedicated QC team (5–10 inspectors)
- In-house R&D engineers (5–10 staff)
- UL, CE, RoHS, and REACH compliance
- Zero-defect target for industrial environments
