Press Tool & Die Systems

With our unique technology and network,
we provide our customers with the most suitable, highly efficient motor cores.

In the global context, it is said that a staggering half of all electricity consumption is attributed to motors. Furthermore, within Japan, over 75% of the power consumed in the industrial sector is by motors. This immense demand for motors speaks to how indispensable they are to both our daily lives and industrial activities.
Against this backdrop, our company contributes to energy conservation and efficiency in society through our precise mold technology and motor core products. In particular, our main products, Press Tool & Die and motor cores for automotive applications, continue to enjoy robust demand.
To meet the increasing expectations of our customers, our company is actively expanding its supply capacity. Specifically, in addition to new capital investments such as the expansion of our Nagano Plant, we are strengthening our production and supply system for Press Tool & Die Systems and motor core products by expanding business with overseas partners and broadening our domestic partnership strategies.
Moving forward, we will continue to contribute to the realization of a sustainable society and the advancement of our customers' "monozukuri" (craftsmanship/manufacturing) through our precise technology and strategic business development.

KURODA's laminated press die "FASTEC® System" was launched in 1976 as a press die for motor cores, based on our polishing technology for spline gauges and precision jigs. This system made it possible to complete all the work processes of punching, laminating, measuring, and assembly within the press process, resulting in a dramatic improvement in quality and productivity. In an era when high-efficiency motors with excellent energy-saving characteristics are in demand, we can manufacture optimal motor cores tailored to customer needs with high precision and efficiency.

FASTEC® is a registered trademark of KURODA, derived from
"FA-stening" (fixing)
and "S-kewing" (skewing
technology) and "TEC-hnology ."

We only accept custom-made dies for "Precision Press Products FASTEC®".

Motor core post-processing (MAGPREX®)
