Cold forging and plastic processing "Bolt Union" that enables high cost performance.

A part that requires high processing technology to connect the engine and the pipe.

Bolt unions serve as fittings that connect pipes that deliver fuel, oil, and coolant to and from the engine. As such, precision and meticulousness are required in terms of dimensions and sizes, and the processing also requires high-level technical skills. By utilizing processing methods such as cold forging, we achieve complex processing with fewer steps. We also excel in cost performance in our manufacturing. 【Production and Technical Points】 ■ Press Method for Improved Precision and Environmental Consideration We have introduced a highly productive press method for shaping materials and creating holes in bolt unions, which enables us to achieve a cutting-free process. The press method allows for the same diameter sizes for both vertical and horizontal holes. By switching from traditional cutting to a press method, we boast low-cost and stable productivity, while also considering environmental impacts in our production processes. ■ Cold Forging and Plastic Processing Our company achieves a cutting-free process through shaping and hole creation from materials using the press method, while balancing environmental conservation and resource protection. Our equipment has a lifespan several times longer than that of cutting drills, demonstrating excellent durability.
