    from new design proposals matching the automaker's needs to parts development, prototyping and mass production.

  • Car Body Press Technology Solving the dilemma of light weight versus safety

    Achieving both light body weight and safety is a tough problem to solve. Simply making the steel plate thinner to save weight diminishes its collision strength. Unipres employs HTSS forming technology along with product design technology to solve this dilemma. By applying our expertise in structural parts, we are aiming for further weight reductions.

    HTSS forming technology

    Freely processing light and strong high tensile strength steel makes it more widely applicable.

    Product design technology

    Light weight and strength are achievedby optimizing body structure.

    Car Body Press Technology Each component making up a car body offers new added-value to the vehicle.

    At Unipres, we make original design proposals for each body module to meet all kinds of automaker needs and realize automobiles with outstanding performance along with light weight. Unipres’s distinctive press technology plays a vital part in every component.

  • Precision Press Technology Pressing also realizes this degree of precision.

    Transmission components for automobiles require precision and strength. Building on our car body press technology, we developed innovative technology for producing transmission parts by means of precision pressing, in place of the conventional casting, forging, and cutting processes. Along with high strength and 1/1000mm-level precision processing, considerable cost savings can be realized. In addition, by pursuing highly efficient manufacturing aimed at resource conservation and CO2 reduction, we are helping to protect the earth. This is the ultimate in press technology, essential for creating automobiles of the future.

    Precision Press Technology Fuel-efficient CVT is kind to the environment.

    We are pursuing new possibilities for press technology, toward the creation of high-performance transmission parts.

  • The world's lightest* floor under-cover made with foam molding material also with excellent aerodynamic, heat resistance, and sound absorption qualities

* 50 percent lighter weight (1.0kg/unit) than conventional products (internal data, 2008 as base point)

    Plastic Press Technology Innovative technology realizes the world's lightest products.

    Plastic parts formerly made by injection molding can now be made by pressing. Using innovative technology derived from our body press know-how, we are producing the world's lightest plastic parts for automobiles, with far greater productivity and at competitive costs. Our goal now is to contribute to overall lighter vehicle weight by applying plastic-forming technology to structural parts.

    Plastic Press Technology Our one-of-a-kind press technology will revolutionize plastic molding.

  • “Unified Commitment to Manufacturing”
    results in consistent high efficiency and quality at all our global sites.

    Production technology is the key to highly efficient, high-quality mass production of compelling products at plants around the world.
    Our highly advanced technology is achieved, through our motto, "Unified Commitment to Manufacturing," and by merging our own unique press and assembly technologies with digital technology in all processes from development to production.

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.

Center pillar

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.
