Frequently Asked Questions
- Are you a shoe insole factory in China?
- Dongguan Goldsea Insole Co., Ltd. is a shoe insole factory in Dongguan, China, supporting OEM/ODM projects from product development and sampling to bulk manufacturing. We also work on foot-care products, braces and body supports, and custom material products. Project-specific materials, tooling and production requirements are reviewed before quotation.
- Can we start with a small pilot order before scaling production?
- Potentially. For qualified product-development projects, Goldsea can evaluate a prototype or small pilot run before moving to repeatable volume production. Feasibility, materials, tooling, target cost and order quantities are reviewed individually, so a small pilot run may not be suitable for every product construction.
