Jintai Industrial Co., Ltd. — 46 Years of Lock Design and Manufacturing, from Mechanical Locks to the IoT

The group established a factory in Dongguan, Guangdong in 1992, and in 2002 expanded and relocated to a new facility, establishing Lita Hardware (Dongguan) Products Co., Ltd. The company adopted the Toyota lean production system, covering product R&D and design, mold making, zinc-aluminum die casting, plastic injection molding, stamping, lathe polishing, painting, product assembly, and quality assurance inspection in a one-stop operation.

For buyers, the practical benefit is: from an idea to a finished product, all processes are controlled in-house — no need to verify die casting, plastic parts, and surface finishing suppliers separately. Development cycles and quality responsibility are consolidated under one window. This capability has enabled Jintai to undertake OEM manufacturing of locks and hardware parts for the Japanese hardware and construction industry, as well as for companies such as Harley-Davidson, HNI, and Dell.

Jintai's business philosophy starts from the buyer: we insist on doing the right things right the first time and meeting customer requirements — from the general manager down to the production line staff, everyone works toward this goal. The implementation method is the Three-Precision Policy. It is not just a slogan on the wall, but an operating system centered on the quality system, inspection data, supplier management, and personnel training.
