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.

24" Color Touchscreen Control
YAMADA 24" touchscreen with 16 selectable languages, stores 1000 tool datasets (stroke height, stroke rate, tool installation height, feed parameters, tool designation, specific tool data).
