Transforming a tremendous amount of parts into a car.

Body Assembly Process -Pressing and Welding-

It is a manufacturing process key to achieving both compatibility and safety.
Even in equipment planning, emphasizing the harmony between people and facilities, designing lines flexibly requiring thorough pursuit of quality and efficiency.
In recent years, as the weight of the car body is required to be reduced, the technology of the press that aims to strengthen the body without increasing the thickness of the steel sheet is an important process that is responsible for the safety and design of the car body.
In addition to conventional technologies such as spot welding in which base materials are joined together by resistive heat, we are actively working on new technologies such as friction welding by friction heat and rivet method.

Paint Process

This is the process that gives the gray iron shell its vivid appearance and color.

Paint is required to not only add color to the car, but to also function as a guard to protect the car body from fading, scratches, and rust.

In the painting process, the application of paint and high-temperature drying are repeated, taking about 8 hours to complete the painting of one car.
Since heat is used, this is the most energy-intensive process in a car body shop, and thus energy conservation is highly important.

The processes of priming, top-coating, baking, polishing, and inspection involve the use of cutting-edge technologies that are constantly evolving, so we must always be ready to take on new challenges and tackle new tasks.

Final Assembly Process

Every single part has its own function. Lights, seats, steering wheels, engines, etc., are meticulously installed breathing life into the car. The process requires the precision to handle thousands of parts, and the flexibility to respond to the electronic, automated, lightweight, and multi-material nature of automobiles due to advances in safety technology and materials.
