FAQ
What makes your corrosion-resistant steel balls superior to competitors?
Our competitive edge comes from three key factors: 1) Advanced production technology with precision control at ±0.001mm tolerance; 2) Strict material selection using only certified raw materials from reputable suppliers; 3) Comprehensive quality testing including metallographic analysis, hardness testing, and salt spray corrosion resistance verification.
How do you ensure product consistency for large volume orders?
We implement several quality control measures: 1) Automated production lines with real-time monitoring; 2) Batch number tracking for full traceability; 3) Statistical process control (SPC) for key parameters; 4) 100% dimensional inspection for small batches and statistical sampling for large orders.
What is your minimum order quantity for custom products?
For standard sizes, our MOQ is 10,000 pieces per specification. For custom dimensions or materials, the MOQ typically ranges from 5,000 to 10,000 pieces depending on the complexity of production requirements. We also offer prototype services with smaller quantities for initial testing.
How long does it take to produce custom steel balls?
Production lead times vary based on order volume and complexity: 1) Standard products: 7-15 working days; 2) Simple customizations: 15-25 working days; 3) Complex custom projects: 25-40 working days. We provide detailed production schedules at the time of order confirmation.
What certifications do your products comply with?
All our products meet international standards including ASTM F2999 (steel ball specifications), DIN 5401 (ball bearing quality), and ISO 3290 (precision ball grades). We can also provide material certificates, inspection reports, and third-party testing documents upon request.
