  • 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.

  • Parts that support collision safety
    of automobiles

    • Frontal collision

      In order to protect passengers from a frontal collision, distortion of the passenger compartment needs to be minimized. On the other hand, the portion of the vehicle in front of the passenger compartment needs to be designed to change shape so that it absorbs the impact of the collision. This requires highly sophisticated components: for example, the front side member is a structural component running from the front of the vehicle to the side of the passenger compartment, so its front portion must crumple easily under stress while the rear portion retains its shape.

    • Side-on collision

      In order to protect passengers from side-on collision, the other vehicle must be prevented from encroaching into the passenger compartment. Components such as the center pillar and side sill need an especially high degree of strength, since they receive direct impact.

    • Rear-end collision

      As well as minimizing distortion of the car body to protect passengers in the car in the event of a rear-end collision, it is also vital to prevent fuel tank damage. For example, in addition to having a very complex shape to secure luggage space in the trunk, the rear side member requires highly sophisticated press forming technology to ensure that it absorbs impacts in the event of a collision.

  • Parts that support handling safety of automobiles


    In addition to fundamental vehicle performance such as traveling, steering and braking, a high level of body rigidity is necessary to achieve stable cruising when making lane changes and turns during high-speed cruising. The rigidity of the steering member, which supports the steering wheel and other components of car steering mechanism, is particularly crucial.
