While serving global customers, Shenglu continuously invests in strengthening its manufacturing capability.
Over years of development, we have established a complete in-house manufacturing chain, covering all critical processes required for bicycle hub and drivetrain component production.
This allows Shenglu to control quality, efficiency and delivery internally, without relying on fragmented outsourcing.

Our in-house manufacturing processes include:
Mechanical metal fabrication and sheet metal processing
----Aluminum forging
----CNC machining
----Cold extrusion and cold forging
----Black oxide and phosphating treatment
----Aluminum anodizing
----Electrophoresis and electroplating
----Heat treatment
----Final assembly and inspection

By completing all major processes within our own facilities, Shenglu ensures stable process coordination and consistent production results across different product programs.

In parallel with process integration, Shenglu actively applies industrial automation to reduce labor intensity and improve manufacturing consistency.

Automation has been implemented in key production stages, including:
----Automated mechanical and sheet metal processing
----Automated CNC machining operations
----Automated hub assembly
----Automated freewheel assembly

By introducing automation at these stages, Shenglu reduces manual variation, stabilizes critical process parameters and supports long-term batch production with predictable quality and output.
Automation is applied selectively where it delivers measurable improvements in consistency and efficiency, while human oversight remains an integral part of the manufacturing system.
