FAQ
What is the minimum order quantity for custom precision steel balls?
Our MOQ starts at 10,000 pieces for standard sizes and 5,000 pieces for custom dimensions, though we may accommodate smaller quantities for prototype development through our sample program. The exact quantity depends on the complexity of your specifications and our current production schedule.
How do you ensure consistent quality across large production runs?
We implement statistical process control (SPC) at every manufacturing stage, with real-time monitoring of critical parameters like hardness, roundness, and surface finish. Our automated sorting systems reject any balls falling outside specified tolerances before packaging, ensuring 100% compliance with your order requirements.
Can you produce steel balls with special magnetic properties?
Yes, we offer both magnetic and non-magnetic variants across our product range. For specialized applications, we can adjust the carbon content and heat treatment process to achieve precise magnetic permeability values. Our engineering team can provide detailed material property reports upon request.
What is your typical lead time for custom orders?
Standard orders ship within 15-20 working days after order confirmation. Custom projects requiring new tooling or special materials typically take 4-6 weeks from final design approval to delivery. We maintain strategic raw material inventories to minimize delays for common alloy types.
Do you provide samples for testing before placing bulk orders?
Absolutely. We offer free sample kits containing representative products from our standard range. For custom specifications, we can produce prototype batches (subject to a tooling fee) that allow you to validate the design before committing to full production. Shipping costs for samples are typically borne by the customer.
