How do you control product quality?

Quality checks cover incoming materials, production and final inspection before shipment. The inspection items depend on the material and agreed specification. Tell us which reports, sampling requirements or additional tests you need so these can be confirmed before order acceptance.

Do you offer samples before bulk order?

Yes. Samples can be arranged for dimensional checks, assembly trials and application evaluation. Send the material, diameter, precision grade and sample quantity. We confirm availability, preparation time, sample cost and shipping arrangements for your request.

Can you customize ball size and material?

Yes. We review requests for non-standard ball sizes, specified materials and application-related requirements. Send a drawing or written specification covering diameter, tolerance, hardness, surface finish and quantity. Manufacturing feasibility is confirmed for the requested combination.

Do you provide OEM and ODM service?

We support OEM orders based on customer specifications, including agreed packaging and private labels. For requests involving product development or design changes, send your drawings and functional requirements so we can review the scope of support. Design and validation responsibilities should be agreed before the project begins.

What is the minimum order for a mixed-size order?

The minimum quantity is confirmed separately for each specification. It depends on the material, diameter, precision grade, processing requirements and stock availability. You can submit several sizes and materials in one enquiry; our quotation lists the minimum quantity and lead time for each item.
