The UPS concept is key to our consistent craftsmanship,
starting from the design stage.
Every step is shaped by UPS (Unipres Production System) activities founded on our motto, “Unified Commitment to Manufacturing.”
Production, development, and management divisions work together to raise productivity and added-value, based on UPS activities,
as we aim for the number one spot among global manufacturers of pressed parts for automobiles.
The latest press and production technologies help us make stronger,
lighter automobile parts.
Worldwide Unipres production sites have the latest in 3000-ton class transfer presses and hot stamp facilities needed for HTSS processing. Leading-edge equipment and production methods go into making future automobiles lighter and safe.
Center pillar manufacturing process
The steps for making center pillars, key body structural parts of a vehicle, are illustrated here.
This is a component in which high rigidity and strength are required to ensure safety.

Hot stamp technology
"Hot" technology achieves strength exceeding that of ultra HTSS.
Steel plate is heated, then hardened by rapid cooling as soon as it has been formed on the press. The resulting hardness, 1350MPa or above, exceeds that of ultra high tensile strength steel. With our world-class productivity, we are expanding application of this technology to meet performance needs.

Scale guard steel sheet (aluminum-plated steel) is used.
