Looking for perfection
for automotive safety Automotive Business Area with recognized technology through perfect quality certification secured test capability of OEM car makers based on the latest dynamometer. We have been producing parts for automotive brake system such as brake discs, brake drums and hubs for more than 20 years.
Currently, we are not only delivering to GM Korea but also exporting to more than 10 countries including USA, Mexico and Uzbekistan. Moreover, we are making our utmost effort to secure products with zero-defect quality by carrying forward development in brake disc tuning field as well.Business Area Production capacity Production line automotive Business Area 8 million pcs / year Brake Disc , Drum, Hub
About our products
What is Hub?
- It plays a role in conveying driving force of car to tires and wheels, and is a part of which disc and drum are assembled.
- All processes are automated and manufactured in order of lathe turning process, drill process and broaching process, and managed by automatic measurement. Machining accuracy is less than max.
- 16 ㎛, which is ultraprecision machining line
What is ㎛ (micrometer)?: 1/1000 mm
What is Disc?
- It is a brake system of which oil pressure pushes the pad of spinning circular shape of disc, which is mainly used for car brake system.
- Mag Hessapp of Germany is used and the line is composed of lathe turning process, automated balance, automatic measurement and automatic carving.
- Machining accuracy is less than 5 ㎛, which is ultraprecision machining line.
What is Drum?
- It is a round drum shape often used for light-weight vehicles or trucks, and is a brake system of which oil pressure pushes brake shoe outward.
- It is equipment of Mazak of Japan and the line is composed of lathe turning process, drill process, honing process, automatic measurement and automatic carving.
- Machining accuracy is less than 5 ㎛, which is ultraprecision machining line.
What is ㎛ (micrometer)?: 1/1000 mm
What is assembly process?
- It is a process of assembling hub with disc or drum, of which lathe turning process is finished, and is considered a simple module stage.
- The assemble line that Disc with hub or Drum with hub combined.
- Depending on models, two parts are automatically assembled and incorporated, and the required screw for this process is automatically provided and pressed.
What is FNC Coating?
- It is one of heat treatment technologies that promotes corrosion resistance, abrasion resistance, fatigue resistance and strength improvement of the treated material by creating compound layer and oxidized layer on the surface of carbon steel and low alloy steel.
- It is a cutting-edge heat treatment process allowing minimization of deformation and prevention of oxidation of the surface.
- It excels in abrasion resistance, corrosion resistance, and fatigue resistance.
- Stable structure of carburizing and nitrification are obtained by using a mixture of gas.
