Can You Open New Molds for Custom Zipper Pulls and Buckles During the Sampling Stage?

Yes. During sampling, we can develop custom zipper pulls and buckles mold tooling to produce hardware that reflects your brand identity — including logo-embossed pulls, unique buckle shapes, or proprietary closures. This process typically starts once your hardware design file is submitted through our design consultation service, where our engineering team reviews feasibility, mold cost, and production lead time.

Mold development timelines vary depending on complexity, but most custom hardware molds take 2–4 weeks to complete, and we recommend confirming your minimum order quantity requirements in advance, since new tooling investment is usually tied to bulk order commitments.

All custom hardware — whether zippers, pulls, or buckles — is tested for tensile strength and corrosion resistance in line with ISO 105-based hardware durability testing methods, ensuring your custom components perform reliably across the bag’s lifecycle.

Once the mold is approved, the finished hardware sample will be integrated into your next physical bag sample for full evaluation, so you can assess fit, finish, and functionality before mass production begins.
