Ripress has been the first European maker to implement a servo-proportional system (composed by inverter, servomotor and gearpump) on an injection moulding machine for thermoplastics
The Ripress solution, called H.E.S. System, anticipates the times regarding the energy saving, dynamics and noise reduction. The virtually immediate response of the servomotors, compared with the traditional variable displacement pumps with electro-mechanical drive, allows an improvement in performance, efficiency and – especially – reliability. The perfect management of pressures and deliveries of the fluid, instantly adjusted to the actual need, prevents the waste of energy and allows a considerable rationalization of the hydraulic circuit. A simplification that also pays off in terms of a matchless value per money, due to the significant cost saving in the making.
