About "Brake Discs"

Brake discs are essential as “critical safety components” that safeguard vehicle safety. They efficiently slow and stop the rotation of the wheels, working in tandem with brake pads to deliver precise braking force. Crafted from high-precision materials resistant to high temperatures and wear, they provide stable performance over extended periods. As a key element in accident prevention and safe driving, they are indispensable parts for vehicle operation. They form part of the trust that enables worry-free driving enjoyment, supporting daily safety.

Marketing Department
Order Received

The Sales Department is responsible for securing orders for parts for new vehicle models and conducts sales activities in collaboration with Development and Production Engineering. Rather than cold calling, we focus on long-term projects by building strong, trust-based relationships with our customers. We remain continuously involved from six months to two years prior to receiving an order, and after receiving an order, we continue through prototyping, mass production launch, price adjustments, and payment collection. We aim to become a long-term partner for our customers by bundling technology, quality, and reliability through cross-departmental team sales, rather than individual efforts.

Development Department
Design

The Development Department supports a vehicle’s stopping power by developing brake discs that combine performance, safety, and reliability. Brake discs, critical components directly linked to a vehicle’s driving safety, require precise and advanced technology throughout the entire process—from material selection and design to thermal analysis and durability testing. Our department is divided into three groups: Design, Preliminary/Analysis, and Testing. Based on CAE analysis and experimental evaluation, we design products that meet diverse requirements such as lightweight construction, high durability, and reduced noise and dust. We are also actively advancing initiatives for next-generation mobility, such as EVs and autonomous vehicles, focusing on development that balances both environmental performance and safety.
