26+ Years of Passion, Precision & Craftsmanship in Die Casting
Founded in 1999, Shenzhen Keyu Metal Products Co., Ltd. (深圳市科宇金属制品有限公司) has grown from a specialized zinc & aluminum die casting foundation into a premier 5,500 m² high-pressure precision foundry. Led by founder Mr. Xie Fengting, we uphold craftsman precision, deep engineering heritage, and promises kept to every global client.
Preserved in our Shenzhen Plant: 1999 Founding Machine
A tribute to the founder's dedication and uncompromising craftsman spirit.
Preserving Our Roots: The Machine That Started It All
In 1999, in the vibrant manufacturing cradle of Shenzhen, KEYU founder Mr. Xie Fengting began managing the zinc die casting department at Like Watch Co. This vintage cold-chamber machine was the very first piece of equipment on which Mr. Xie learned the craft of die casting, personally assembling, maintaining, and tuning every single mechanical component.
When Like Watch Co. relocated and expanded, they presented this machine to Mr. Xie in recognition of its extraordinary significance to his career. Through more than two decades of rapid industrial transformation, while other factories discarded old equipment, KEYU made an unwavering commitment: this founding machine will never be sold and is permanently preserved in our entrance hall.
As inscribed on our workshop plaque: 'Never forget the well-digger when drinking water.' Today, as automated robotic arms from LK and YIZUMI extract glowing metal castings every 18 seconds, this vintage machine remains our daily compass. It reminds our 150+ engineers that true precision is rooted in mechanical reverence, craftsman spirit, and promises kept to every customer.
