Toroid Corporation

Quality isn't a department.
It's our operating system.

Every Toroid transformer passes through a multi-stage quality process, from incoming material verification through final performance testing. That discipline is what earns a place in the equipment our customers build.

Quality Management SystemISO 9001:2015

Certified. Audited. Continuously improved.

Our ISO 9001:2015 certification is more than a wall hanging. It's the framework behind every process, from how we receive our raw materials to how we train our team, handle non-conformances, and measure customer satisfaction.

What this means for you: predictable quality, documented traceability, and a partner whose processes hold up under your audits.

The Quality Process

Every transformer passes five controlled stages.

A documented workflow from raw material to shipping label: no step skipped, no exception left untraced.

01

Incoming Inspection

Every lot of raw steel, wire, and insulation verified against spec before release to production.

02

In-Process Controls

Winding tension, turns count, and impregnation monitored and logged at every station.

03

Electrical Testing

Hi-pot, turns ratio, inductance, and insulation resistance, tested on 100% of units rather than sampled.

04

Final Inspection

Visual, dimensional, and functional verification before labeling and serialization.

05

Packaging & Traceability

Individual serial numbers tie every unit back to materials, operators, and test results.

Testing & Validation

Instruments, methods, and the discipline to use them.

Our test floor is equipped for production volume and engineering depth. Whether it's 100-unit verification or first-article qualification against your AQL, we capture the data and keep the records.

  • Hi-Pot Dielectric Testing

    AC and DC dielectric withstand at specified voltages per UL, IEC, and customer specifications.

  • Turns Ratio & Polarity

    Precision TTR measurement to verify winding integrity and correct output relationships.

  • Insulation Resistance (IR)

    Megger testing at multiple voltages to confirm insulation integrity and absence of contamination.

  • Load & Thermal Characterization

    Full-load temperature rise, regulation, and efficiency verification under specified conditions.

  • Leakage Current (Medical)

    Touch and patient leakage verification for IEC 60601-1 compliance on medical-grade designs.

  • Custom Qualification Testing

    First-article, PPAP, and customer-specific validation protocols, planned and documented up front.
