Battery case for 48V mild hybrid vehicles
An example of combining a design proposal based on plastic CAE simulation and the high mechanical strength of the Leona SG series to pass a drop impact test.

Peripheral parts of fuel cell stacks.
Low elution is required because excess ions can cause trouble in the transfer of electrons in the fuel cell.

A cover that covers the upper part of the engine cylinder to prevent engine oil from splashing. 
High heat resistance is required because of its proximity to the engine, which is a heat source.

Bracket for mounting the anti-vibration device attached to the engine unit. 
High strength and fatigue resistance are required to mount the vibration isolator that supports the engine.

Support parts for automobile engine timing chains. 
Friction and wear characteristics are required since they are in contact with the chain being driven.

This case covers the timing chain of an automobile engine to prevent oil splashing.
High heat resistance is required because of its proximity to the engine, and damping performance is sometimes required to reduce noise.

Oil pumps for engines, brakes, etc., and cooling pumps for batteries, etc. 
Since the product consists of multiple molded parts, good moldability is also required.

Pipes that serve as a path for radiator fluid that cools the engine.
The product must be heat resistant because of its proximity to the engine, hydrolysis resistant because of the refrigerant it passes through, and formability as a pipe.

A component that is mounted inside the fuel tank and sends purified fuel to the engine through the upper flange. 
Fuel resistance is required.

Parts for fixing mirrors used by drivers to check the side and rear of the vehicle. 
The part must be strong and rigid enough not to break even if a person hangs from it, and must have a beautiful appearance and weather resistance even without coloring.

Cases for automotive interior door handles and handle surroundings.
Automobile interior parts are required to pass the standard value of VOC (Volatile Organic Compounds) amount, light resistance, and chemical resistance.

A component used to fix a mirror for checking rearward vision. 
In recent years, housings for forward detection ADAS components are also integrated. High appearance without coloring and rigidity to prevent blurring are required.

Installed in the center pillar, this part is a metal part coated with POM resin or other material to maintain sliding properties with the seatbelt (polyester).
It is also required to have impact resistance in the event of a vehicle collision and light resistance because it is an interior component.

A button on the buckle portion that is pressed when unbuckling a seatbelt.
The buttons are required to have the weather resistance, low VOC (Volatile Organic Compounds), and impact resistance to resist breakage even in an emergency, which are required for automobile interior parts.

Gears used in motors that drive doors, wipers, seats, etc.
They are subject to heavy loads and require durability and creep resistance.

A key housing that unlocks and locks car doors and turns the engine on and off.
Since it is visible to the public, it is required to have a good appearance.

Lens barrels and lens spacers used for various cameras mounted on vehicles.
High dimensional stability is required to accommodate optical components.

Head-up display components installed in vehicles.
