Mobility
The rise of AI, the emergence of IoT, and the widespread use of mobile apps are driving a revolution in mobility. As a result, automobiles are becoming increasingly integrated into people's daily lives—not just as a means of transporting people and goods, but also as tools for connecting to social networks.
For anyone in search of auto part
Enhancing mobility for a safer, more enriching journey

It’s said that each automobile is made up of approximately thousands of parts of various sizes.
Every single part plays a vital role in ensuring the user's safe driving experience, which is why each one is manufactured under rigorous quality standards. TNK's automotive components are also produced and shipped after meeting those same stringent standards. Thanks to TNK's high-precision parts, cars become more reliable, refined, and safe.
Recruitment results
1. Fuel pump parts

High-precision outer diameter machining and D-cut processing are available.
By precisely finishing the D-cut shape designed for anti-rotation, we reduce rattling between mating components and enhance the performance of the fuel pump.TNK successfully achieve mass production of millions of units per month while maintaining exceptional precision and uncompromising quality..
2. Variable valve timing components (OCV)

This component is part of the variable valve timing solenoid system, and its smooth operation helps enhance combustion efficiency
The material used is highly wear-resistant but very difficult to process.TNK's unique technology make it high-precision processing.We are doing the following.
3. Injector parts

As a component for urea SCR injectors, high-precision machining of outer diameter and straightness is possible even with highly corrosion-resistant materials.
With TNK's unique grinding capabilities, TNK process irregularly shaped shafts both internally and externally, enhancing the stability and quality of fuel atomization
