Custom Product FAQs
Can you manufacture chains and belts to non-standard widths and pitches?
Yes. We specialize in custom manufacturing. For
silent chains / toothed chains
, we can produce any width from 50 mm to 500 mm, and custom pitches beyond the standard 12.7 mm and 25.4 mm. For
annealing furnace mesh belts
, we can customize pitch, helix pitch, wire diameter, belt width, and belt length according to your drawings or specifications. Please provide your required parameters, and our engineers will confirm feasibility and lead time.
What materials are available for high-temperature applications?
For chains, we offer Q235, manganese steel, alloy steel, stainless steel 304, 316, and heat-resistant grades (e.g., 2520 / 310S). For glass shear blades, the standard material is W6Mo5Cr4V2 (M2 high-speed steel), with optional all-steel or tipped (hardfaced) versions. For annealing furnace mesh belts, we provide A3 low carbon steel, 45# steel, 1Cr13, 1Cr17, 1Cr18Ni9Ti (321), and 2520 (310S). Please specify your operating temperature and environment, and we will recommend the most cost-effective material.
What is the minimum order quantity (MOQ) for custom products?
We have no high MOQ. For standard custom sizes, MOQ can be as low as 5 meters for chains or 1 set of shear blades (matching pair). For mesh belts, MOQ is generally 1 full belt (any length). Prototype orders are welcome. For large-volume production, we offer competitive pricing and faster delivery. Contact us with your quantity, and we will provide a tailored quote.
What is the typical lead time for custom-made products?
Lead time depends on complexity and quantity.
Standard custom chains (non-standard width/pitch): 7–15 days
Glass shear blades (custom angle or multi-cut): 5–10 days
Annealing furnace mesh belts (fully custom): 10–20 days
We keep semi-finished materials in stock for fast production. Expedited service (3–5 days) is available for urgent orders. For stock items, we offer same-day shipping. Please contact us for an exact delivery date based on your specifications.
