Reference diameter: 0.03–0.15 mm. Discuss tight winding space, finish diameter, insulation integrity and the motor’s operating temperature.
Send: conductor diameter, slot or coil drawing, thermal class, winding speed and monthly volume.
Discuss a motor winding →Reference: 0.02–0.10 mm. Discuss insulation build, soldering or stripping, electrical tests and the winding process used in power or communication electronics.
Send: target resistance, finished diameter, termination process and spool preference.
Discuss an inductor wire →Reference: 0.03–0.12 mm. Review coil geometry, wire tolerance, electrical resistance and insulation requirements.
Send: coil drawing, duty cycle, operating environment and trial quantity.
Discuss a relay coil →Reference: 0.015–0.08 mm. Discuss micro-fine winding and, where needed, self-bonding construction and forming conditions.
Send: wire size, coil former dimensions, bonding method and target impedance.
Discuss a voice coil →Small changes in diameter or insulation build can change winding fit. Jinwei can review a 0.025 mm conductor in UEW, PEW or EIW according to the requested process.
Send: current datasheet, drawing, application, insulation preference and delivery country.
Discuss a precision coil →DOCUMENTED SAMPLE
A 2024 test report records the submitted sample and the tests in its stated scope. Use it as a starting point for documentation review, not as certification of other sizes or constructions.
