Automotive Electronic Brake System (EBS) Valve Block

Valve Block

Manufacturing site: Hamakita Plant

Electronic brake systems (EBS) are key components in anti-lock brake systems (ABS), which prevent wheel locking and skidding when the brakes are applied, and electronic stability control (ESC), which uses sensors to monitor the vehicle driving status and controls stable driving and stopping. The electronic brake system optimally applies braking force to the four wheels, contributing to enhanced vehicle stability.

Diesel Fuel Injection Control Pump Housing

Housing

Manufacturing site: Hamakita Plant

This diesel engine fuel injection device converts fuel (diesel fuel) into high-pressure mist and completely burns the fuel, thereby decreasing harmful emissions, vibration, noise, and so on and boosting fuel efficiency. The pump that controls the fuel injection must be able to withstand high-pressure operation, so some parts need to have holes with tolerances of no more than 7 µm and flatness of no more 10 µm. Our high-precision machining technologies contribute to creating products that can withstand use at approximately 2,000 atm of pressure.

Diesel Fuel Injection Control Pump Cylinder

Cylinder

Manufacturing site: Miai Machinery Plant

Pressure is applied directly to the interior surface of the cylinder holes, and as a result, pressure can be concentrated depending on the configuration of gouges and the damage, causing breakage and cracking. This can lead to damage and fuel leaks or impairment of function, so improvement of the whole surface and stabilization are needed. Our high-precision machining technologies contribute to creating products that can withstand use at approximately 2,000 atm of pressure, as in the case of the housing, and support smooth engine rotation.
