For Thin-wall, Packaging and Caps and Closures Applications

For molders preferring high-speed all-electric injection molding machines for their packaging applications, the SE-HSZ PACK Series brings the advantages of Sumitomo (SHI) Demag’s advanced direct-drive motor technology to high-speed packaging molding in the mid-tonnage range. Available in 280 and 350 metric tons models, the SE-HSZ PACK provides the energy efficiency, cleaner molding environment and precision benefits of an all-electric combined with the higher speeds and pressures typically found only on high-performance hybrids and hydraulics.

Equipped with direct-drive motors for both injection and clamping, the SE-HSZ PACK is ideally suited for thin-wall and packaging parts that run on fast cycle times and require high injection speeds. These direct-drive motors have a lighter, more compact, low-inertia/high-torque design that draws power only as it is needed, is easier and faster to stop and start, and is exceptionally precise. The resulting performance specs speak for themselves:

  • Higher Injection speeds of 550 to 650 mm/sec
  • Velocity response of 25 milliseconds
  • Injection pressures up to 39,740 psi
  • Mold open/close speed of 1300 mm/sec

Innovative features unique to Sumitomo (SHI) Demag, can also be found on the SE-HSZ PACK:

  • Low-shear, low-temperature SM screw
  • Double Center Press Platen design that ensures superior surface pressure balance even in the center surface area of the mold
  • Twin-cylinder, high-contact-force nozzle-touch system that provides contact force equivalent to a hydraulic clamp machine plus excellent mold protection and faster cycle times
  • Constant feedback clamp force sensor for exceptionally stable clamp force control
  • High-precision mold height adjustment using a highly precise rotary encoder

Raising the bar for injection molding machine control, the SE-HSZ PACK is equipped with Sumitomo’s Z Control, an easy-to-use PC-based control that provides an exceptional level of injection molding precision with low-pressure filling and reduced clamp force. Unique attributes of the Z include:

  • Flow Front Control (FFC) System (patent pending) that optimizes the flow front further allowing control of low internal pressures inside the cavities
  • Minimum Clamping Molding (MCM) System which helps avoid flash, burn spots and shorts shots, and can reduce mold wear, cycle time and power consumption
  • Simple Process Setting (SPS) System which allows easy setup and operations while helping the operator avoid oversights and mistakes
