FAQ
What is the minimum order quantity for custom stainless steel balls?
Our minimum order quantity starts from 5,000 pieces for standard customizations and 20,000 pieces for complex special shapes. We evaluate each project individually to provide flexible solutions for both prototype development and mass production.
How do you ensure the quality consistency of stainless steel balls?
We implement a comprehensive quality management system with multiple inspection stages: incoming material inspection, in-process quality control, and final product verification. Each batch comes with detailed inspection reports including dimensional data and surface analysis.
What surface treatments are available for stainless steel balls?
Our surface treatment options include electropolishing, passivation, black oxide coating, PVD coating, and custom color marking. The treatment selection depends on the application requirements for corrosion resistance, wear resistance, or aesthetic appearance.
How long does it take to produce custom stainless steel balls?
The production lead time depends on the complexity of the project. Standard orders typically take 15-20 working days, while custom projects with special shapes or surface treatments may require 25-35 working days. We provide detailed production schedules during quotation.
Do you provide samples before mass production?
Yes, we offer free sample production for qualified projects. The sample lead time is usually 7-10 working days. We use the same production processes and quality standards for samples as for mass production to ensure accurate representation of the final product.
What certifications do your stainless steel balls have?
Our products comply with multiple international standards including ISO 9001 (quality management), IATF 16949 (automotive industry), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety). We can also provide material certification reports upon request.
How do you handle quality issues after delivery?
We maintain complete traceability for all products and offer a 12-month quality warranty. In case of any quality concerns, our after-sales team will investigate within 24 hours and provide solutions including replacement, refund, or technical support based on the specific situation.
Can you develop special-shaped stainless steel balls?
Yes, our engineering team has extensive experience in developing non-standard stainless steel balls. We have successfully produced flat-faced balls, hollow balls, satellite balls, and other special shapes for various industrial applications. Each custom project starts with detailed technical review and prototype development.
What payment terms do you accept for international orders?
For international clients, we offer flexible payment terms including 30% deposit with balance before shipment, letter of credit (LC), and PayPal for sample orders. We work with reliable freight forwarders to provide DDP (Delivered Duty Paid) service for major destinations.
