Applications
Which marine projects we take on
Marine and offshore components often operate under constant moisture, vibration and corrosive conditions. We support projects involving fittings, pump and valve parts, propeller shafts, manifolds and deck hardware, machined from corrosion-resistant materials with controlled interfaces and documented inspection.
WHY MACHINE MARINE PARTS WITH TONGYONG
From prototype to marine-grade production
We machine precision components for marine and offshore equipment, including pump parts, valve bodies, propeller shafts, manifolds and deck hardware. Using CNC milling, turning, 5-axis machining and EDM, we manufacture parts that withstand demanding marine operating conditions.
Marine applications require reliable performance under saltwater exposure, vibration and continuous operation. We machine corrosion-resistant materials with controlled tolerances and documented inspection, helping prototypes transition smoothly into repeatable production.

Common questions
Marine machining FAQs
Can you machine corrosion-resistant marine metals?
Yes — marine-grade stainless, bronze, duplex and aluminium chosen to resist salt water and corrosion over long service.
Do you make sealing and pressure parts?
Yes — valve bodies, pump parts and fittings with clean sealing faces for seawater and fluid systems.
Prototype and production volumes?
Both — from a single prototype to repeatable production batches with documented inspection.
Can you handle replacement and obsolete parts?
Yes — with reverse engineering we recreate marine parts from a sample or limited drawing.
What files do you need?
A 3D model (STEP / IGES) plus a drawing, or a sample part for reverse engineering.
