The items listed below are required for automobile frame components, and our products and services are deeply related to each of them. KTH is involved with the part development in respect to the manufacturability of each part for formability and cost reduction. KTH manufactures high-level automotive products with performance and quality required by our clients and their customers.
The Bulkhead is positioned at the front of the automobile. Radiators, condensers, head lights, etc., are mounted at the automobile assembly plants. 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.
The Front Wheelhouse 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.
The Front Wheelhouse Upper Member is welded to the Front Wheelhouse Component. It is instrumental in the body structure to more evenly distribute frontal crash energy throughout the front of the vehicle for occupant protection.
The Front Side Frame is positioned from the front bumper to the front of the cabin and it cradles the engine from both sides. While carrying the engine, which is the largest and heaviest component of the automobile, it also enhances the strength and rigidity of the entire automobile. It is designed to absorb and disperse the shock backward, and drop the engine downward so it will not be pushed into the cabin, or the frame itself will crumple on the impact.
To achieve both the strength and the ability to collapse within one product, steels with different specifications are welded together with laser welding. By using a tailored, blank material machined as a single steel stock, we have realized multiple forms while enhancing the productivity.
The Rear Frame is the frame positioned from the rear seat to the rear bumper. Strength and rigidity are the key components to protect the cabin and fuel tank in the case of a collision. The Rear Frame should maintain rigidity while expanding the distance between the frames to give the occupant comfort and a variety of seat layouts. It has a complex and rugged shape, requiring high forming technology.
The Rear Wheelhouse is welded to the Rear Frame Component on the outboard side of the vehicle. The shape of the part houses the rear tires and strut assembly. The main stamping of this comp is usually made of a mild steel material to allow for sufficient stretch when drawing the part during the stamping process. Depending on the vehicle, the comp will support the pillar, parcel shelf, seat belt harnesses, cargo hooks, and electronic and sound system units.
The Floor Frame Component runs longitudinal from the front Side Frame and ties in to the Center Floor Frame and Inside Sill. This component, along with the Inside Sill, aids in improving the torsional and bending rigidity which then aids in reducing the noise, vibration, and harshness (NVH) of the vehicle. Ultimately, the floor panel will weld to this component.
The Center Floor Frame runs longitudinal from the Front Side Frame to the Mid Floor Cross Member. This component, along with the Inside Sill, aids in improving the torsional and bending rigidity which then aids in reducing the noise, vibration, and harshness (NVH) of the vehicle. The U-shaped members allow room for the drive train and exhaust system routing. Ultimately, the floor panel will weld to this component.
The Inside Sill runs longitudinal from the Front Side Frame to the Rear Frame on the outboard sides of the vehicle. The Inside Sill provides bending and rigidity improvement but is also instrumental in the support of the Side Pillars and redirecting frontal impact energy for collision safety.
The Floor Tunnel runs longitudinal from the Front Side Frame to the Mid Floor Cross Member in the center of the vehicle. It welds directly to the Mid Floor Cross Member. The shape of the part allows for the center console to be attached during assembly. It also provides an area for the drive train and exhaust systems to be routed to the rear of the vehicle in the cavity below the part.
The Spare Tire Pan is located in the rear of the vehicle directly below the trunk cargo area. The main purpose of this part is to house the spare tire. It is usually made of a mild steel material for better stretch because of the deep draw shape of the main stamping.
The Mid Floor Comp is a cross body comp which welds to the Inside Sill and Rear Frame components. This component also aids in improving the torsional and bending rigidity which aids in reducing the noise, vibration, and harshness (NVH) of the vehicle. Ultimately, the floor panel will weld to this component.
The Rear Floor Cross Member is a cross body part which welds directly to the Rear Frame component. This component aids in improving the torsional and bending rigidity which aids in reducing the noise, vibration, and harshness (NVH) of the vehicle. The mating shape of this component helps support the Spare Tire Pan component.
The Door Beams are installed, parallel to the ground, inside each door. They protect the occupants by instantaneously and effectively absorbing the energy from impact during a front and side collision. KTH uses a unique quenching process that tremendously enhances the strength, while at the same time makes the Door Beam very lightweight.
