SACMI IPS MACHINES FOR PRODUCING PET PREFORMS
The modern beverage industry is extremely dynamic and the fast-changing market demands high productivity, ever-greater efficiency, hygiene, versatility and size changeover flexibility. To respond to these needs Sacmi has designed and developed the IPS range, focussing on the following key factors to achieve the required competitiveness and minimise customers’ total operating costs: Performance Quality Energy saving Flexibility IPS - INJECTION SYSTEM FOR PET PREFORMS 1 CLAMPING UNIT Designed using FEM structural analysis to optimise mechanical inertia and ensure excellent resistance to mechanical stress. Hydraulic actuators equipped with personalised digital servo-valve, to guarantee ultra-fast lock-to-lock times, thus reducing the preform cycle time. 2 INJECTION UNIT The injection unit consists of an extruder with an electrical-drive plasticizing screw and a shooting pot controlled by servo valve. This solution ensures high performance and energy savings. 3 PET PREFORMS POST COOLING The take-out robot is driven by latest-generation belt-free (and, therefore, maintenance-free) linear motors, ensuring accuracy, speed and repeatability of robot movements. To save energy, a braking energy recovery system has been installed; this works during deceleration of the motors. 4 FLEXIBILITY AND HMI Thanks to special Sacmi-developed PET preform production software, the user interface is a simple one that lets users configure the machine simply by entering preform dimensions and thickness.
