A custom airtight zipper order succeeds or fails on the parameters agreed up front. This checklist covers what to supply at enquiry, what to validate at sample stage, and what to sign off before mass production.
Step 1: Supply these parameters with your enquiry
- Use case and application
- Length range (5 cm to 100 m) and effective opening length
- Size or tape width
- Colour
- Opening style and slider count
- Host material to be joined
- Target waterproof rating (IPX6 / IPX7 / IPX8)
- Oil resistance requirement
- Test conditions and acceptance criteria
- Sample, trial production and mass production quantities
Step 2: Validate at sample stage
| Check | What to confirm |
|---|---|
| Model and colour | Matches the drawing and the target assembly |
| Length and opening style | Effective opening length is correct in the finished assembly |
| Slider and end structure | Type, count and end treatment as specified |
| Dimensions and tolerances | Measured against the agreed drawing |
| Cycle testing | 3,000+ open/close cycles as published |
| Airtight / watertight testing | At the rating and test conditions agreed |
| Assembly test with your material | Installed into the real host material, not tested loose |
| Packaging and batch identification | Traceability and packing agreed before scale-up |
Step 3: Agree before mass production
- Lead time — sampling is a 7–15 day reference and mass production 15–30 days, subject to confirmation
- Sampling method and acceptance criteria
- Batch identification and traceability
- Documentation: test reports for the agreed rating
