30 Years of Precision Metal Manufacturing

From a small precision hardware shop to a two-plant operation with a full in-house process chain, dedicated to custom and contract manufacturing of precision metal structural parts.

Focused on the development, production and processing of metal enclosures, frames, chassis and precision hardware

Huizhou Sisheng Intelligent Equipment Technology Co., Ltd. has been engaged in precision hardware manufacturing for 30 years. With two plants in Houjie (Dongguan) and Zhenlong (Huizhou), Guangdong, we cover five core processes: CNC precision machining, press forming, aluminum die casting, laser tube cutting and robotic welding.

We provide one-stop contract manufacturing of metal structural parts — from drawing review and prototyping to mass production — to customers in energy storage, industrial automation, robotics, 3C electronics, EV battery PACK, IDC data centers and height-adjustable equipment. Over the years we have served hundreds of equipment manufacturers and new-energy companies.

Customers often struggle with multi-process projects: no single supplier, tight lead times and high precision requirements. Sisheng answers this with two collaborating plants and a complete in-house process chain, delivering stable, reliable and predictable results.
