FAQ – Middia Ceramic Blades
1. What ceramic materials do you use for your blades?We use high‑purity zirconia (ZrO₂) and alumina (Al₂O₃) ceramics. Zirconia offers extreme toughness and edge retention, while alumina provides excellent cost‑effectiveness for less demanding applications.
2. Can you customize blade sizes, shapes, or holes?Absolutely. Our in‑house R&D team can produce custom designs based on your 2D/3D drawings or physical samples. We support OEM/ODM with tolerances as tight as ±0.01 mm.
3. What is the minimum order quantity (MOQ) for custom blades?For standard items, MOQ is 100 pieces. For fully customized shapes, MOQ starts at 500 pieces, but we can be flexible for trial orders or sample verification.
4. How do your ceramic blades compare to steel blades?Ceramic blades are much harder (Hv 1500+ vs. steel ~600), stay sharp 10‑15 times longer, and are non‑magnetic, anti‑static, and corrosion‑resistant. They are ideal for cutting paper, film, fiber, and food without metal contamination.
5. How can I get samples before placing a bulk order?You can order samples directly on our Alibaba page or contact our sales team. In‑stock samples ship within 2 days; custom samples take 7‑10 days for production and approval.
6. What is your typical production lead time?For stock ready‑to‑ship products, we deliver within 7 days. For bulk custom orders, lead time is approximately 30 days, depending on complexity and quantity. We always inform you of the exact schedule before order confirmation.
