About Us

Koosei Precision is an engineer-founded manufacturer specializing in precision mould components and custom tooling parts for customers across Europe, North America, and Japan.

Located in Chang'an Town, Dongguan, one of China's most established precision manufacturing hubs, we benefit from an industrial ecosystem developed over more than three decades. Chang'an is internationally recognized for its dense concentration of mould makers, material suppliers, and specialized processing providers, forming one of the world's most complete precision manufacturing supply chains.

This unique manufacturing environment enables us to respond quickly to customer requirements while maintaining exceptional quality, competitive lead times, and reliable production capacity. Unlike many suppliers, Koosei Precision was founded and is managed by engineers with extensive machining experience. We evaluate every drawing for manufacturability, dimensional accuracy, and process optimization before production begins, helping customers reduce risks and improve overall project efficiency.

Today, we serve manufacturers in Germany, the United States, Canada, the United Kingdom, France, Italy, Japan, and other industrial markets, supplying precision mould inserts, cores & cavities, punches, dies, fixture components, and custom-machined parts used in automotive, medical, electronics, semiconductor, and industrial automation applications.
