Quality & Manufacturing
Our Ningbo production line covers copper-iron co-firing, molding, winding and testing — built around engineering qualification and process control.
Engineering Sample to Pilot Ramp
We are a focused, growing manufacturer. Today our focus is disciplined engineering qualification and pilot production ramp — not volume claims we cannot yet back.
Engineering samples
Samples ship within 3 working days so your team can qualify on the bench, not from a brochure.
Pilot ramp discipline
Production processes are qualified per series before volume commitments are made.
Direct factory access
Your engineers talk to ours — no distributor layer between your design and our line.
How We Build
Core & coil engineering
Material selection, winding design and inductance/DCR targets set at the start of each series.
Construction
Copper-iron co-firing or metal-alloy molding per series, with process parameters locked per part.
Inspection
Electrical, mechanical and visual checks on every lot against the qualification record.
Qualification support
Datasheets, curves and sample support so you can qualify the part in your application.
What We Measure
| Item | What is checked |
|---|---|
| Inductance (L) | Value and tolerance at test frequency |
| DCR | Typ and max per part number |
| Saturation (Isat) | Inductance drop at defined current conditions |
| RMS current (Irms) | Temperature rise under continuous current |
| Mechanical | Dimensions, flatness and termination integrity |
| Visual | Appearance and marking per specification |
Audits & Visits Welcome
Located at No.501 Mingzhou West Road, Beilun District, Ningbo — we welcome factory audits and design reviews. See the line, meet the engineers, then decide.
