Bumper Reinforce & Crash Box
These are shock absorbers fixed to the front and rear of au automobile. The bumper reinforce is an elongated part extending to right and left sides of a vehicle, and one crash box is attached to right and left of the bumper reinforce, respectively. These parts play a role of protecting occupants from front-rear collisions. The strength of the bumper reinforce is increased using ultra-high tensile strength steel plate (ultra-high tensile strength steel materials) and hot stamping in order to receive collision energy. The crash box absorbs collision energy by being crushed to contribute to reduce damages.
Strengths of Bumper Reinforce and Crush Box
Bumper Reinforce Designed to Realize Low Cost and Weight Reduction
In order to absorb more collision energy, with the aim of increasing the strength, we provide designs suitable for a vehicle by utilizing ultra-high tensile strength steel materials and various methods. Further, we realize not only the increasing of strength, but also cost reduction and weight reduction at the same time through optimum design based on the CAE analysis and actual machine evaluation.
Crush Box Unique to Toyotetsu Developed
In order to secure a wide occupant space, in recent automobiles, a space in front of the engine room is reduced. Therefore, a space for disposing the crush boxes having sufficient energy absorption performance is limited. We have developed a cross-section structure unique to Toyotetsu capable of absorbing the same collision energy as before under such restrictions, and we design and offer to our customers small -sized highly efficient crush box with reduced weight.

Center Body Pillar
The center body pillar is a pillar-shaped part that is located between the front and rear doors and connects the floor and the roof. Since it plays an important role of protecting occupants at the time of a side collision, materials having strength higher than that of other body parts is used. Accordingly, it is one of our main products using technologies such as ultra-high tensile strength and hot stamping.
Strengths of Center Body Pillar
Design for Protecting People at the Time of Collisions
At the time of front-rear collisions, the engine room or the trunk room absorbs shocks. However, at the time of a side collision, it is necessary to absorb shocks using a little space to protect occupants. Since the front and rear doors are just connected to the vehicle skeleton by hinges, in fact, the most of shocks are absorbed by the center body pillar. Accordingly, in order to absorb shocks to the maximum extent with a saved space, we repeatedly perform the CAE (Computer Aided Engineering) analysis and actual machine evaluation to design the center body pillar by combining a plurality of materials and giving special design to its shape.
Technologies to Create Complex Shapes
In order to improve running performance and fuel efficiency, it is necessary to reduce the weight of the center body pillar. For that purpose, it is essential to enhance the strength of materials used. However, when the ultra-high tensile strength steel materials having high strength are used, it becomes difficult to obtain a complex shape which satisfies favorable vehicle design and shock absorbance performance in some cases. In such a case, we may use the hot stamping technology in some cases. In this way, we propose the most appropriate materials and shapes while taking influences on performance and cost into consideration to realize the manufacturing of high quality products.

Radiator Support
The radiator support is a part that is attached to the forefront of an automobile, and supports the radiator for cooling the engine, the head lamps, the bumper, and the grille. It suppresses twisting in front of a vehicle body during running, and contributes to stable running. By utilizing our strength of having know-how for steel plates and resins, we also realize mass production of a new structure in which a part of the radiator support is formed of resins.
Product Details
Resin Radiator Support Upper
The resin radiator support upper is a multi-functional part which realizes weight reduction by making a part, which was conventionally formed of iron, with resins, and has a function as an intake duct.
Product Details
Floor Cross
The floor cross is a part which is located on a floor surface (floor) of a vehicle and serves as the base to which seats are attached.
It plays a role of improving the rigidity of a vehicle body, and at the same time, it plays a role of protecting occupants at the time of side collisions.
To achieve these performances at the same time, ultra-high tensile strength steel materials are adopted to impart higher strength to the floor cross.
Product Details
Rocker Outer
The rocker outer is an elongated part which is located on a side face lower part (between front and rear tires) of an automobile and attached along a lower side of the door. The rocker outer plays roles of protecting occupants at the time of front and side collisions, and enhancing the rigidity of the entire vehicle body. For that purpose, ultra-high tensile strength steel materials are employed to impart higher strength to the rocker outer. Some products employ Tailor Welded Blank (TWB). With this, an optimum plate thickness is realized to significantly contribute to weight reduction of a vehicle and also contribute to the improvement of fuel efficiency and running performance.

Front Side Member
The front side member is a part that is located at the vehicle front side, and plays an important role of protecting occupants at the time of front collisions. The assembly of large complex parts are finished at high quality using our excellent welding technology.
Product Details
Rear Side Member
Rear Side Member
The rear side members are key parts which are located at left and right of the vehicle rear side and constitute a skeleton of a vehicle. So, the rear side members play an important role of protecting occupants at the time of rear collisions. The rear side members ensure the rigidity of a vehicle and efficiently absorb and disperse energy at the time of collisions to contribute to reduce damages. In addition, through the improvement of the rigidity of a vehicle body, the rear side members also contribute to the improvement of running stability and handling performance.

Front Floor Center Panel
Front Floor Center Panel
The front floor center panel is an important part that is located at the center of the floor structure of a vehicle and contributes to the ensuring of the rigidity at the front footwell and the absorption of energy at the time of collisions. The front floor center panel improves the rigidity of the entire vehicle body and realizes safety performance and running stability.
In addition, the assembly of large parts are finished at high quality using our excellent welding technology.
