Frequently Asked Questions (FAQ)
-
What is the material of the nylon sleeve?
We use high-quality nylon (PA6 or PA66) which offers excellent impact resistance and durability. Custom materials are available upon request. -
Is the 0.5mm tolerance guaranteed for all sizes?
Yes, our production process ensures ±0.5mm tolerance for all standard and custom sizes. Each batch is inspected before shipment. -
What does the Mill Test Report include?
The report covers material properties such as tensile strength, elongation at break, impact resistance (Izod), and hardness. It provides full traceability. -
Can I get a sample before ordering in bulk?
Absolutely. We offer samples for evaluation. Sample cost is negotiable, and we can deliver within 7–10 days after mold preparation. -
How do I install the sleeve on concrete sleepers?
The sleeve is placed into the formwork before concrete pouring. It stays in place during casting and provides a precise hole for later insertion of bolts or dowels. -
What is the minimum order quantity (MOQ)?
For standard sizes, MOQ is 500 pieces. For custom sizes, MOQ may vary depending on tooling investment. Please contact us for details. -
Are the sleeves UV resistant?
Standard nylon has good UV resistance for outdoor applications. If you require extended UV exposure, we can add UV stabilizers or supply black color which offers better protection. -
Do you provide custom packaging or labeling?
Yes, we can package according to your requirements, including neutral packaging, branded boxes, or bulk packing on pallets.
