- Lead Time:
- 1–3 business days (ready to ship if in stock).
- Note: Stock status can be confirmed via real-time inventory checks.
2. Customized Orders
- Modified Standards (e.g., changing pore size or length of a stock item):

- Prototyping: 3–4 weeks (design validation + sample production).
- Bulk Production: 4–6 weeks (for orders >50 units).
3. Expedited Options

Factors Affecting Lead Times
| Factor | Impact |
|---|---|
| Material Rarity | Special material type may add 1–2 weeks. |
| Certifications | ISO/QC docs add 3–5 days. |
| Testing Requirements | Bubble point/flow tests add 3 days. |
| Order Volume | Bulk (>500 units) may reduce time. |
How to Ensure Faster Delivery
- Choose Standard Designs (e.g., 316L, 15–50µm).
- Opt for 304 Stainless Steel (faster than 316L for some sizes).
- Provide Clear Specs Upfront (avoid back-and-forth delays).
