EPS Core
Optimized for Motor Core Production
With the EPS Core Series, YAMADA sets a new benchmark for motor core lamination. Designed with 3 or 4 guided pressure columns and a robust slide, these presses deliver exceptional stability and precision even under high-speed, high-load conditions. Our ceramic-aluminium alloy slides reduce moving mass while maintaining extreme rigidity, ensuring unparalleled bottom-dead-center accuracy. Every detail is engineered to meet the strict tolerances required for advanced motor components, empowering manufacturers to achieve consistent quality and efficiency from the very first stroke.
- Fixed stroke crank motion
- Highly rigid frame to withstand any eccentric load
- Wide bolsters for large dies

Heat & Cool System
Perfect Parts from the First Stroke
Precision starts at the very first stroke. Yamada’s Heat & Cool system keeps the press at a constant operating temperature — from the first part to the last. Before production begins, the system automatically heats the press frame and slide to the optimal temperature using a built-in timer, so the machine is ready when production starts — without any loss of time. Once running, a circulating oil loop maintains the temperature within ±1 °C through integrated heating and cooling.
The result: consistent part quality, stable accuracy, and less scrap — without any additional cost. The Heat & Cool system comes standard with every Yamada press, ensuring perfect performance right from the start.
