Customer approval samples are the first practical proof that a custom transformer can meet the application requirement and be repeated in production. BaoHui Tech prepares samples with drawings, material control, winding instructions, electrical tests, inspection records, and revision notes so the approval process is traceable.
An Approval Sample Should Represent Production
A sample built by special handling is not useful if normal production cannot repeat it. The sample should use approved materials, controlled winding methods, defined insulation steps, and the same test limits intended for future orders.
This is important for both high frequency transformers and power transformers because physical construction affects leakage, capacitance, thermal rise, regulation, insulation, and noise.
What BaoHui Tech Prepares
BaoHui Tech aligns sample preparation with the risk level and customer requirements of the project.
- Drawing revision, BOM, winding instruction, and marking details
- Material selection for core, bobbin, wire, insulation, shield, varnish, and terminals
- Electrical tests such as turns ratio, inductance, leakage, resistance, no-load current, and hipot
- Dimensional inspection, appearance review, terminal check, and packaging notes
- Revision record, customer feedback, and approval status before production release
Why Documentation Matters
Approval documentation protects both buyer and manufacturer. It clarifies what was tested, what changed, and what construction is approved.
When repeat orders begin, the approval record becomes the baseline for production quality and change control.
