Supplier-declared, pending confirmation

CNC-turned pump shafts in stainless steel, duplex stainless steel, and carbon steel, including friction-welded slender shafts and interference-fit assemblies for marine and industrial applications.
CNC-machined stainless steel components for mechanical seal assemblies, produced to tight tolerances for reliable sealing performance.

CNC-machined stainless steel multi-hole plate flanges and threaded oil pipe connectors, including American standard and custom thread specifications.

Alloy steel and 45# carbon steel machined components with optional surface treatments including hard chrome plating, electroless nickel-phosphorus (ENP) coating, and hardening to HRC45.

Precision-machined PEEK (polyether ether ketone) cylindrical components for applications requiring chemical resistance, low weight, or electrical insulation.
An automated CNC production line supports high-volume orders for pump shafts and standard components while the facility also accommodates flexible small-batch runs for custom or prototype parts.
60 machines across a 6,000 m² plant, including Mazak five-axis machining centers, turn-mill centers, Mikron machines, Niigata horizontal machining centers, and cylindrical, surface and centerless grinders.
A temperature-controlled inspection room with two Hexagon CMMs, one Zeiss CMM and a projector measurement system supports consistent, documented quality on every batch.
The facility holds both ISO 9001:2015 and GJB 9001C-2017 (the Chinese defense equipment quality management standard), providing documented quality control across all production runs.
In-house or coordinated processing covers stainless steel, duplex stainless steel, alloy steel, carbon steel, and PEEK, with surface treatments including hard chrome plating, electroless nickel-phosphorus coating, and hardening.
Hanweite has been exporting since obtaining ISO 9001 certification and import/export qualification in 2007, and holds a Chinese Customs Import/Export Registration Certificate, with industrial buyers in Europe, the United States, and Australia.
Product lines include duplex stainless steel marine pump shafts assembled with interference fit and oil pipe threaded connectors, indicating documented experience with demanding corrosion and pressure environments.
