Increase battery manufacturing productivity with optimised machine automation

For lithium battery production applications, machines must ensure high throughput matched with control accuracy. Trio helps machine builders achieve this by providing control solutions that combine high speed and precision motion with scalable automation.

The productivity and quality of the processes within lithium battery manufacture are highly dependent on axis control and synchronisation. Trio’s expertise is focused on motion synchronisation supported with flexible and scalable automation solutions.

Trio manufactures motion-centric controllers, I/O systems, HMIs, servo drives and motors, as well as SCARA robots, and development takes place within a single, easy to use software environment. Trio also designs and supports applications for OEM machine builders.
