The Donggang head plant — pump-and-nozzle works with two production and two auxiliary workshops
Plunger-and-barrel, nozzle and delivery valve — the three precision pairs at the heart of every diesel pump. Batch-produced for international markets with stable, repeatable geometry.
Donggang head plant and works, a Shenyang sales company, the common-rail R&D plant and the in-house trading arm — factory, channel and development under one group.
CNC grinding and EDM machines for element production are designed and built by the works itself — the reason tolerances stay consistent across decades of production runs.
A provincial high-tech enterprise with a municipal enterprise technology R&D centre, long-term research cooperation agreements, and a quality management system certified to ISO 9001.
Parts, machines and offices of the Donggang works — the same lines that produce this programme.
