Automotive Products of TOYOTETSU

The Toyotetsu Group produces a wide range of automotive parts, including body parts, functional parts, electronic parts, and interior parts.
When we collect the body parts we produce, we handle a large number of products so that we can create a car skeleton.
As a body skeleton manufacturer, we are developing components by leveraging our high technological and production capabilities to reduce the weight and increase the rigidity of vehicle bodies.
Category lists

Bumper Reinforce & Crash Box

Bumper Reinforce & Crash Box
This is a part that is fixed to the front and rear of an automobile.
The bumper reinforce is a long part that extends to the left and right of the vehicle, and the crash box takes one piece each on the right and left of the part, and it plays the role of protecting the body skeleton and passengers from front and rear collisions in both cases.
Bumper reinforcement is enhanced with ultra-high tensile strength and hot stamping to absorb collision energy. The crash box absorbs collision energy by collapsing itself.

Center Body Pillar

Center Body Pillar
It is a columnar part located between the front and rear doors and connecting from the floor to the roof.
Since it is an important part to protect passengers when other vehicles collide with each other from the side of the vehicle, materials that are particularly hard (high strength) are used compared to other body parts.
Our mainstay products use technologies such as ultra-high-tensile steel, hot stamps, and structural adhesive.

Radiator Support

Radiator Support
Parts that are attached to the front of the body to support radiators and headlamps that cool the engine.
Contributes to stable driving by suppressing the torsion of the front body when driving.
Taking advantage of our expertise in steel plates and resins, we are also developing new structures that are partially converted into resins.

Floor Cross

Floor Cross
This part is located on the floor of an automobile and serves as the base for mounting the sheet.
Ultra-high tensile strength is used to improve body rigidity and to protect passengers in the event of a collision from the side.

Front Suspension Member

Front Suspension Member
It is a part that connects the suspension parts with the body parts, and it holds the arm that determines how the tires move.
Since it also affects the stable running of automobiles and the comfort of riding, it is provided with strength and rigidity by high press and welding technology in thick plates.

Suspension Arm

ロアアーム_1
This is an important part that connects the suspension members and tires and determines the position and orientation of the tires.This function receives lateral force during cornering and longitudinal force during acceleration and deceleration.
Since it also affects the stable running of automobiles and the comfort of riding, high strength and rigidity are provided by using HITEN while it is a thick plate and a difficult-to-form shape.

Suspension Tower

サスペンションタワー_1
This is a component that holds a shock absorber or spring that absorbs vibration or impact that the tire receives from the road surface.
Since it also affects the stable running of automobiles and the comfort of riding, it is provided with strength and rigidity by high press and welding technology in thick plates.

Rear Axle Beam

Rear Axle Beam
This part mainly comprises the rear suspension located on the rear wheel side of small cars.This reduces the impact from the road surface while driving, contributing to stable driving and riding comfort.
Therefore, it has high torsional rigidity.

Power Module Housing

Power Module Housing
One of the components that make up the inverters mounted on electric vehicles such as HV, EV, and FCV. Various parts are assembled by the customer.
By integrally molding many components, high dimensional accuracy and low cost are realized.

Busbar

Busbar
This part transmits the input current from the HV battery into the inverter.
Connect various components electrically.
We realize designs and manufacturing that satisfy insulation performance even in severe environments with high voltage and high current.

Sensor Housing

Sensor Housing
This component outputs high voltage and high current from the inverter to the motor.
This is an important component that serves as the basis for the components (current sensors) that detect the current inside the inverter.
This technology achieves high dimensional accuracy and low cost even in large and complicated situations.

Injection molding

Multi Uni Pipe

Multi Uni Pipe
This is a resin pipe through which oil, cooling water, air, etc. are passed. Both hard and soft resins can be molded.
As a result of mass production, it is used in parts (oil receivers) that drip oil onto the gears in the transmission.
Dripping the optimum amount of oil at the optimum position contributes to improved fuel efficiency.

Brake Pedal

Brake Pedal
The brake pedal is the interface for the brake system.
To stop a heavy vehicle with the force of a person's step, the force of the step must be amplified. The brake pedal uses the lever ratio (this principle) to assist in part of its amplification and to control the braking amount of the brake.
