Hydraulic Dampers
As high-performance vibration control devices, hydraulic dampers support large-scale structures.
We are developing products that meet diversifying needs in fields such as oil dampers, friction dampers, and viscous dampers for seismic isolation and vibration control. In particular, the oil dampers for vibration control that we independently developed have attracted attention as high-performance vibration control devices that demonstrate stable damping performance and are used in many structures including bridges, schools, and hospitals.
Koyo Seiki has an established track record as a specialized manufacturer of hydraulic equipment, and its hydraulic cylinders and hydraulic jacks in particular have earned a strong reputation for high quality and reliability overseas as well. The long cylinders used in construction equipment and other machinery receive support from many fields as a result of our technologies and production capacities at world-leading levels.

Injection-Molding Machines
Injection molding technology realizes effective use of limited resources.
As a pioneer of injection-molding machines used to produce rubber and plastic products, we continue to develop at the cutting edge of the times. Our newest models achieve substantially higher accuracy and support both precision and ultra-precision molding, achieving high-cycle molding. In addition, we are developing various testing machines based on the technologies that we have accumulated from injection-molding machines.
As a leading company in the field of injection-molding machines that has superior technological capabilities, we develop and manufacture high-quality products that address the issues and needs of various production sites in multiple industries. We strive to create new demand and develop new products on a daily basis.
