A State-of-the-Art Clean Factory, through
our Unique Technology and Knowledge
Mazda brought together production technology developed in-house and the knowledge gained through decades of
experience in manufacturing, and the result was this advanced, ultra-clean factory. It has earned its high reputation.
The first simultaneous reduction in VOC and CO2 in the world
Three-Layer Wet Paint System technology
Intermediate coat, color base and clear top coat are applied in sequence, and then all
three baked together in this newly-developed method... the first in the world to
simultaneously slash both CO2 and volatile organic compounds (VOC), which have
considerable environmental impact. This technology made it possible to reduce VOC
usage by 45%, and reduce energy consumption (CO2 equivalent) by 15%, as well as
reducing cost. The technology was adopted in all domestic production lines by April

World's first friction heat aluminum joining technology
In 2003, Mazda was the first in the world to develop a new aluminum joining
technology based on friction heat, slashing electricity consumption by about 99% from
conventional resistance welding. The new technology eliminates the massive electricity
consumption, huge equipment, cooling water and
compressed air systems required for resistance
welding, providing significant energy-saving
benefits and lower cost. The technology was used
in vehicles starting with the RX-8 announced in
2003.

World's first friction heat aluminum-steel joining technology
In June 2005, Mazda extended its aluminum joining technology based on friction
heat, and developed the first application capable of joining aluminum and steel.
Conventional welding of different metals, such as steel and aluminum, has been
extremely complex, but this new Mazda technology makes it simple while at the
same time ensuring a join free of contact corrosion. The new technology is being
used in the new Mazda Roadster scheduled to be
released in August 2005, to join the aluminum
trunk lid and the steel bolt retainers. We will
adopt the technology in other places to join steel
and aluminum, making it possible to assemble
even lighter cars for improved fuel efficiency.
