QC Framework
Quality Built Into the Process, Not Inspected In
TOPWALLET runs five QC gates so that what you receive is what we claimed — and what we claimed is what your customer experiences. Acceptance limits are set at AQL 0.65 (better than 99.5% of units arriving defect-free in practice), every unit passes functional testing before packing, and every batch is traceable from raw material to final shipment. The same five gates protect every wallet in the product catalogue and every custom order that leaves the production line.
>99.5%
Units arrive defect-free in practice (AQL 0.65) — fewer chargebacks and customer complaints on your side
100%
Functional testing before packing — every unit, not a sample of the batch
48 h
Replacement dispatch if a confirmed defect ever reaches you — no waiting weeks for a solution
Incoming QC — material certificates are cross-checked against your purchase specification before a single part is cut.
Final QC — every unit checked for function and appearance before packaging, with pass/fail tallies logged per batch.
5 QC Gates
Every wallet passes through five independent inspection checkpoints before it leaves the factory. Each gate has defined criteria, documented equipment, and a retention record.
Incoming QC (IQC)
Every incoming material lot is verified before it enters production.
First Article Inspection (FAI)
The first unit of every production run is fully inspected before the rest of the batch is released. FAI dimensional data comes straight from the machining and stamping process, closing the loop between what engineering designed and what production delivers.
In-Process QC
Random patrol inspections during the production run to catch drift before it becomes a batch defect.
Final QC
100% inspection of appearance, function, and packaging before units are boxed.
Outgoing QC (OQC)
A sampling audit before the shipment leaves the facility.
Batch Tracking
Traceability System
Every batch carries a unique traceability code that links the finished product back to its entire production history.
Raw material supplier batch number → incoming inspection report
CNC program version and machine ID → machining parameter log
Surface treatment bath ID, temperature, and duration → process record
Assembly station and operator ID → assembly log
Final inspection device calibration certificate → inspection record
Shipping carton ID and carrier tracking number → dispatch record
Non-Conforming Handling
When a defect is detected, the response follows a fixed protocol designed to contain, analyze, and correct the issue without delay.
Discovery & Isolation
The affected batch is immediately quarantined. A red tag is applied and the batch is moved to the NCR holding area.
Root Cause Analysis
Engineering reviews the inspection data, process parameters, and material certificates. For repeat issues, a video call is scheduled with the customer within 24 hours to review findings together.
Corrective Action
The line is corrected before restart. Affected units are sorted, reworked, or scrapped based on the defect type.
Replacement Shipment
If defective units have already shipped, replacement units are dispatched within 48 hours of claim confirmation at no charge.
Verification
How to Verify Our Quality Claims
We publish our standards so you can check them yourself. Any of the claims on this page can be verified three ways, without trusting a brochure.
Check the Batch Code
The YYMMDD-Shift-Line-OperatorID code on your carton links back to IQC sheets, CMM reports, process logs, and shipping records for that exact batch. Send us a photo of the code and we will return the batch dossier within 24 hours.
Request Test Documentation
FAI dimension reports, hardness readings, shielding attenuation results, and OQC release signatures are archived per batch and can be provided as PDF copies or viewed on the factory floor.
Run a Live Virtual Audit
We schedule video audits where you watch the retained sample rack, inspection stations, and records in real time. Your own QA team or a third-party agency (SGS, Bureau Veritas, Intertek) gets the same access.
Evidence Gallery
The following documents and physical records are maintained for every batch and are available for review during a factory visit or virtual audit.
IQC Record Sheets
Material certificates, hardness readings, and shielding test results filed by supplier lot number.
CMM Inspection Reports
Dimensional point-cloud data and tolerance charts for first-article and patrol inspections.
Retention Sample Rack
Sealed sample boxes organized by month and batch code, stored in a temperature-controlled room with access log.
All photographs and scan copies of original records can be viewed in person during a scheduled factory tour. When the batch ships, these same records travel with the packaging and logistics documentation, so your own inspectors see the same evidence we do.

Frequently Asked Questions
Our acceptance quality limit is AQL 0.65 for minor defects, with zero tolerance for critical functional failures. First Article Inspection is 100%. Final functional test is 100%. Outgoing QC sampling follows ISO 2859-1 General Inspection Level II.
Five pieces from every production batch are sealed and retained for 12 months in a controlled storage area. Each sample box is labeled with the full batch traceability code and can be cross-referenced against inspection records, material certificates, and shipping documentation.
Report the issue with photos and the batch code from the carton label. We validate the claim against our retained sample and inspection records. Confirmed defects are replaced within 48 hours at no charge. For repeat issues, we schedule a video call to review root-cause data and preventive actions together.
Yes. Third-party pre-shipment inspection can be arranged through agencies such as SGS, Bureau Veritas, or Intertek. The inspection scope, sampling plan, and AQL are agreed in advance and added to the purchase order. The cost of third-party inspection is borne by the customer unless otherwise negotiated.

Send us your product idea or a reference sample. A sales engineer will walk you through the relevant stages — tooling, sampling, production and QC — and come back with dates and costs.
