FAQ
What is the minimum order quantity for custom steel balls?
Our MOQ starts from 5,000 pieces for standard sizes and 10,000 pieces for customized specifications. For prototype development, we accept sample orders of 500-1,000 pieces with additional tooling fees.
How do you ensure dimensional accuracy for micro steel balls below 1mm?
We employ specialized cold heading machines with 0.0005mm precision and optical sorting systems with 0.1μm resolution. Each batch undergoes three-dimensional measurement using laser scanning technology before packaging.
What certifications do your products comply with?
Our manufacturing system maintains ISO9001:2015, IATF16949:2016 automotive quality standard, ISO14001:2015 environmental management, and ISO45001:2018 occupational health certifications. Products meet RoHS, REACH, and California Proposition 65 requirements.
How long is the production lead time for customized orders?
Standard orders ship within 15 working days after payment confirmation. Customized projects require 25-40 days depending on complexity, including 7-10 days for tooling preparation and 15-25 days for production and quality inspection.
What payment terms do you accept for international trade?
We offer flexible payment solutions including: 30% T/T deposit with balance before shipment, 100% irrevocable L/C at sight, and DP (Documents against Payment) for established clients. For orders above USD 50,000, we accept 60-day DA (Documents against Acceptance) with credit insurance.
