Applications
Which energy projects we take on
Energy components often operate under pressure and in demanding environments. Customers come to us for turbine shafts, valve bodies, flow components, pump parts and other precision-machined hardware used across energy systems, machined from corrosion- and heat-resistant metals with documented inspection.
Why machine energy parts with Tongyong
From Prototype to Reliable Production
We machine turbine shafts, valve bodies, pump and flow components for the energy industry using CNC milling, turning, 5-axis machining and EDM. Working with stainless steel, duplex stainless, Inconel and other engineering alloys, we help customers achieve precise fit, sealing performance and reliable production.
Energy components often operate under pressure, elevated temperatures and corrosive environments. We machine production-grade materials so prototypes validate fit and sealing before moving into repeatable production with documented inspection.

Common questions
Energy machining FAQs
Can you machine corrosion-resistant alloys?
Yes — stainless, duplex, Inconel and specialty steels for parts that resist pressure, heat and corrosion over long service.
Do you machine pressure and sealing parts?
Yes — valve bodies, flanges and flow parts with clean sealing faces, machined to pressure standards.
Prototype and production volumes?
Both — from a single prototype to repeatable production batches with documented inspection.
What tolerances and quality control?
Critical features from around ±0.01 mm, verified by CMM under our ISO 9001 system.
What files do you need?
A 3D model (STEP / IGES) plus a drawing for critical dimensions, tolerances and finish.
