Manufacturing capability
Mechanical & hydraulic manufacturing capability
TNG's factory in the HCMC Auto Mechanics IZ runs CNC/NC lathes, welding robots and an in-house quality-control process end to end — building hydraulic cylinders, motors, valves and power units to engineering standard.
Equipment
Machinery & production line
We invest in a matched set of CNC/NC machine tools, welding robots and metrology equipment to control tolerances and surface finish to ISO standards — so every part matches its drawing.
CNC/NC lathes
Precision turning of shafts, cylinder bodies and rotational parts with tight tolerance control per drawing.
Automated welding robots
Robotic welding for consistent, stable welds and high throughput on steel structures and cylinder bodies.
CNC milling machining centre
Milling, drilling and reaming of flanges and complex parts in a single set-up.
Metrology & inspection equipment
Measuring dimensions, roughness and concentricity to sign off each stage.

Quality control
Quality-control (QC) process
Every product passes a multi-stage QC process — from incoming material to final sign-off — to guarantee it meets specification and operating durability.
Incoming material inspection
Checking material certificates and blanks before they enter machining.
In-process control
Monitoring tolerances and roughness on the line at every operation.
Dimensional & tolerance inspection
Measuring key dimensions with metrology equipment, recorded and filed.
Final inspection & sign-off
Overall check, seal/pressure testing and sign-off before delivery.
