Automobile Framework Parts

Automobile framework parts, which are the H-ONE's key products, are greatly involved in the safety performance, environmental performance, operability, usability of the interior space, and design of the automobile.
Reduction of impact to the occupants and pedestrians during the accidents. Trimming off the weight for fuel efficiency. Rigidity contributing to enjoyment of maneuvering the car. User friendly airy cabins. Stylish designs.
These are the things required for automobiles without any questions, and our products are deeply related with them. H-ONE is developing these from the planning and designing phases together with our clients, manufacturing high level products with performance and quality required by clients and society.

Front Bulkhead Comp

Front Bulkhead Comp

The bulkhead partitioning engine room, positioned at the front of the automobile white body. Radiators, condensers, head lights, etc., are mounted at the automobile assembly plants. In recent days, front bulkheads are designed with a closed cross-section structure to enhance the rigidity of the whole automobile, while considering the design of the automobile.

Front Side Frame Comp

Front Side Frame Comp

The frame positioned from the front bumper to front of the cabin, as it is cradling the engine from both sides. While carrying the engine, which is the largest and heaviest component of the automobile, it also takes a role to enhance the strength and rigidity of the whole automobile. It is designed to absorb and disperse the shock backward, drop the engine downward so it will not be pushed into the cabin, or the frame itself will crumple on the impact.
To achieve the strength and ability to collapse within one product, steels with different specifications are welded together with laser welding. By using a tailored blank material machined as it is a single steel stock, we have realized multiple forms while enhancing the productivity.

Rear Frame Comp

Rear Frame Comp

This is the frame from the rear seat to the rear bumper. Strength and rigidity to protect the cabin and fuel tank during the collision is required.
To maintain the rigidity while expanding the distance between the frames to give occupant comfort and variety of seat layouts, it has a complex and rugged shape, requiring high forming technology.

Pillar Comp

Pillar Comp

The pillar is a column reaching from the floor of the cabin to the roof. It is called as A-pillar, B-pillar, and C-pillar respectively from the front windshield.
Its main role was to hold the roof and the door in past years, but it is now a part that will determine the collision safety performance. While maintaining the openings such as doors and tailgates, it will disperse the energy during the collision, preventing the cabin collapsing, and maintaining the survival space for the occupants. Along with the required strength, the shape that will not obscure the vision is also required.
H-ONE has realized narrow but strong pillars by using the molding technology for the extra-high strength steel sheet that is stronger than the high strength steel sheet.

Front Wheelhouse Comp

Front Wheelhouse Comp

This is constructed with the dome-shaped wheelhouse that shrouds the tires and damper space that holds the suspension dampers. The damper space and its surrounding are required to be strong enough to withstand the forces transmitted from the road, and lightness is required more than the strength for the wheelhouse.

Door Beam

Door Beam

This is a parts installed parallel to the ground inside a door. It will protect the occupants by instantaneously and effectively absorb the energy of impact during the front and side collision.
H-ONE is using unique quenching process to tremendously enhance the strength, while making it very light at the same time.
