Heavy-Duty Zinc Alloy Open D Ring with Spring Lock for Leather Crafts

Our sample development is priced through negotiation, and the sample fee can be deducted from future mass production costs. Standard samples are completed within 10 working days, with expedited options available upon negotiation. The minimum order quantity is 100 pieces.

Our CNC machining cost is calculated as 'material cost + machine hour cost + tooling/fixture cost + surface treatment + profit'. The higher price is influenced by factors such as equipment precision, full inspection of product quality for each batch, and the use of high-end spindles.

We are equipped with measuring instruments such as CMM (coordinate measuring machine), roughness tester, and air gauge. We perform 100% inspection of critical dimensions and can provide full inspection reports.

If any quality issue arises with our products, we will respond within 24 hours. Once it is confirmed to be our responsibility, we will either remake the products or issue a refund at no cost, and we will also bear the shipping cost for emergency replacement.

We can provide treatments such as anodizing, electroplating, blackening, sandblasting, and vacuum heat treatment, depending on the material properties. These require an additional 3 days. We can also outsource the processes while maintaining unified quality control.
