Sang Cheong was founded in Hong Kong in 1985. In 1997, we built a standardized production facility in Houjie, Dongguan. Dongguan Golden Metal Handbag Accessories Co., Ltd. now acts as the production base, covering approximately 6,500 square meters with more than 100 professional staff.
Our facility is equipped for mold processing, precision die-casting, polishing, zipper production and professional testing. We specialize in nylon zippers, metal zippers and bag hardware accessories including hooks, buckles, locks, nameplates, decorative parts and buttons.
As an integrated manufacturer covering R&D, production and processing, we provide full-process OEM/ODM customization services, helping customers move from design concept to stable mass production.
From tooling, die-casting, assembly and polishing to full-process zipper production, our in-house equipment and mature workflows support faster development, consistent quality and controllable lead times.
Grinder, Wire EDM, CNC lathe, EDM machine, discharge machining equipment and 3D printer support independent tooling and fast sampling.
