    SE7M Micro Series Direct-Drive All-Electrics injection moulding machines available from Tasman Machinery

    Tasman Machinery

    Tasman Machinery introduce the SE7M Micro Series Direct-Drive All-Electrics injection moulding machines, specifically designed for micro-moulding applications requiring high levels of precision (extremely tight dimensional tolerances) and exceptional productivity (high yield, multi-cavity, etc.).

    The SE7M injection moulding machines feature four direct-drive, Sumitomo AC servo motors with full closed-loop control and digital sensors. All four motors are beltless, providing superior mechanical efficiency, repeatability and durability, and avoiding the problems associated with belt adjustment and dust. Plasticising, injection, clamping and ejection are controlled by these motors.

    The SK-II injection control is available to help moulders achieve high levels of injection fill precision and peak pressure stability. Furthermore, Sumitomo's advanced direct-drive motor technology employs a lighter, compact, low inertia design that:

    • Provides the speeds, pressures and torque for the most demanding applications
    • Draws power only as it is needed
    • Is easier and faster to stop and start
    • Provides exceptional precision and repeatability
    Other specialised features of the SE7M injection moulding machines include:
    • Synchro-plast control mode for resins with low viscosity or uneven pellet size. In this mode, control of both the screw position and back pressure are optimised, ensuring plasticising stability
    • New algorithm and software for the servo control that achieves faster response and improved stability
    • Flash speed mode that provides fast response control of velocity and pressure, before and after V/P switch-over. It is used to prevent short shots and warp from over-packing
    • High-speed, multi-action ejector operation including ejector operation during mould close
    • Injection speeds up to 300mm/sec and injection and hold pressures up to 28,426 psi 
    • Wider distance between tie bars to load larger, multi-cavity moulds and 3-plate moulds
    • CPP (Centre Press Platen) clamp design for improved force distribution, elimination of short-shot and flash problems, and improved mould protection
