Quality control
We do not hold a factory certificate. What we do is inspect every part in line and arrange third-party testing for the batch you order — which is what most buyers actually need, because a certificate states what a factory can do, not what arrived in your carton.
Six checkpoints
- Incoming material Compound lot recorded against the order. Colour checked against the approved chip before it goes to a press.
- First article The first good part is measured and photographed, then held. You get the photo; if you want the part, we ship it.
- In-process patrol Dimension and appearance checked through the run, not only at the end. Flash and short shots are caught at the press.
- Post-cure verification Temperature and dwell logged — 200 °C for 2 hours. This is the step that stops complaints about smell.
- Final inspection 100% in-line on dimension, colour, logo, fit and function. Sampled AQL 2.5 where 100% is impractical.
- Packing check Quantity, polybag, carton marking and carton drop condition before the box is sealed.
What we measure, and with what
| Characteristic | Method |
|---|---|
| Dimension | Calipers and profile projector against the drawing |
| Hardness | Shore A durometer, ASTM D2240, on every batch |
| Colour | Visual match to the approved cured chip under daylight lamp |
| Logo and legend | Registration and legibility check, plus rub test on printed legends |
| Function | Peak force and snap ratio on keypads; leak check on seals and pouches |
| Appearance | Flash, short shots, flow marks, bubbles — 100% visual |
| Odour | Sealed-bag check after post-curing |
When you need a lab report
We arrange third-party testing through SGS, Intertek or BV depending on your market. Typical combinations and what they cost:
| Market | Combination | Typical cost | Days |
|---|---|---|---|
| United States | ASTM F963 + CPSIA | $300–800 | 7–14 |
| European Union | EN71-1/2/3 + REACH | $400–900 | 10–15 |
| Canada | CCPSA | $300–700 | 7–14 |
| Australia | AS/NZS ISO 8124 | $300–700 | 10–14 |
One rule worth knowing: a Children’s Product Certificate must be issued by the importer, not the factory. We can supply the test report from a CPSC-accepted laboratory; only you can sign the CPC. Any supplier offering to "give you a CPC" misunderstands the rule.
