Jinxin Transmission

Quality and inspection

Checks tied to the drawing and the defined production stage

Inspection scope follows the product configuration and order requirements, from incoming material and in-process dimensions through assembly settings and retained manufacturing records.

Incoming Material Control

Forging and casting stock is verified against drawing specification before entering the machining process.

In-Process Dimensional Control

Gear tooth profile, lead, and housing bore alignment are checked at defined stages using CNC gear grinding and inspection equipment.

Assembly & Running Checks

Completed gearboxes are assembled to specified bearing preload and backlash settings, with running checks performed prior to dispatch.

Documentation & Traceability

Key manufacturing records are retained against each order to support after-sales reference.
