DONGSHIN RB
Your advantage in the packaging industry. Dongshin RB Electric guarantees high cycle times for the production of packaging articles of any shape, thickness and size.
The machine is the result of intense development work, the aim of which has been to offer solid and effective answers to the increasingly demanding needs of the packaging market. The guideline of the project was to concentrate in a single product high performance in terms of speed and precision, high quality and reliability of the components, careful engineering of the ergonomics of the solutions adopted and particular attention to the containment of energy consumption.
By the using of multiple electric motors and a mechanical structure specially designed for high cycle times, Dongshin RB guarantees injection speeds up to 400 mm/s without particular structural stress.
