Injection capacities from 29g to 1685g (PS) across the range. These all-electric injection moulding machines offer energy savings of up to 80% when compared to conventional hydraulic drive solutions, and substantially reduced cycle times due to fully overlapping movements. NOVA eT machines are equipped as standard with: ETHERNET VARAN PROTOCOL control system Smart Flex 2 clamping unit with generous tie bar spacing to accommodate larger moulds and a moving platen that rides on linear bearings for excellent platen parallelism and reduced energy use Robust ball-screw injection drive system with high speed, high load ball screws Multi touch screen TACTUM based user interface with full range of control parameters Ready for AMICO 4.0 wireless remote service access SEND ME INFORMATION Specifications NOVA eT All ELECTRIC INJECTION MOULDING MACHINE SPECIFICATION Features CLAMPING UNIT 5-point double toggle clamp Euromap platen configuration Hardened tie bars Electric motor with belt driven clamp movements Linear bearings for moving platen guidance and support Powered mould height control Automatic central lubrication system by means of electric pump Seven‐stage mould closing speed profile Seven‐stage mould opening speed profile Closed loop control of Mould closing and opening stages Digital reading of moving platen position displayed on the operator interface Auto-adjustment of Mould height and clamping force Digital control and reading of cross‐head position on the operator interface Digital reading of clamping force displayed on the operator interface Electric servo motors for ejection Three stage ejection speed profile Ejection force control Digital reading of ejector position displayed on the operator interface Ejector overlapped movement at opening Repeated ejection with stroke and speed control Ejector return signal Complete overlapping of three movements: mould opening, ejection, screw rotation INJECTION UNIT Axial ball-screw injection drive system High speed, high load ball screws Injection unit sliding on linear bearings Electric drive for carriage movements General purpose screw profile, suitable for most types of thermoplastic materials Bimetallic barrel Injection unit driven by ball screws to assure perfect nozzle centring Ceramic energy saving heater bands Alarm threshold for set temperature range Injection speed and pressure profiles Switch to holding pressure triggered by screw position, hydraulic pressure or time Digital reading of screw position displayed on the operator interface Adjustable screw rotation speed profile Screw rotation delay Adjustable back‐pressure profile Digital reading of back‐pressure displayed on the operator interface Decompression before and after screw recovery Auto purge program MOTORS AND DRIVES Fan cooled servo motors Temperature control for motors and drives Brushless motors with permanent magnets Independent motors and drives for mould, ejector, injection and plasticising ELECTRICAL SYSTEM Interlocked main switch to prevent the electrical cabinet from being opened when press is energised Magneto thermal and static relays to control plasticising cylinder heating Fan for air circulation in the electrical cabinet Fully labelled electrical circuits COOLING CIRCUIT Different solutions for cooling are available for the customers depending on specific requirements.
