A manufacturing partner built around complex parts.
Founded in 2014, Lianwei has developed from a CNC machining factory into a business combining precision components, tooling and surface finishing. The company’s 2026 introduction describes production bases in Shenzhen and Dongguan, a 13,000 m² plant footprint and more than 200 professional staff. Our focus is high-precision, difficult and complex metal components.
Precision component machining
Our manufacturing resources include multi-axis machining centers, turn-mill equipment and supporting processes. Magnesium is a particular focus alongside aluminum, zinc alloys and stainless steel.
Connected manufacturing
Aluminum and magnesium die-cast mold manufacturing and surface finishing extend the scope beyond machining. The appropriate combination is defined for each project.
Quality and communication
Dimensional inspection, material analysis and process quality control support the manufacturing workflow. Clear drawings and agreed acceptance requirements are central to each project.
