SE-HDZ Series 
(220 to 450 metric tons – 2150 to 4410 kN) 


Fully electric machine to cover clamp forces from 2,150 kN(220 tf) to 4,410 kN(tf).
While emphasizing cost-performance, excellent stability in molding is attained.


The new mid-sized SE-HDZ Series all-electric injection molding machines, 242 to 496 US tons, were specifically designed for high-duty applications such as thick parts and parts with cycle times in excess of 15 seconds.


With the SE-HDZ, you’ll find high hold pressures, up to 31,718 psi, that exactly match the injection pressures. For large part molding, there are also high injection capacities, up to 75% greater than a typical machine. Equipped to deliver full power for up to 40% of the cycle, this machine series ensures exceptional stability, outstanding machine durability and the ability to handle even the toughest high-duty application.

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

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

The all-electric SE-HDZ features four, Sumitomo-built, AC servo motors with digital-to-digital, closed-loop control. All four motions — plasticizing, injection, clamping and ejection — are controlled by these motors. Using highly energy efficient servo motors, the SE-HD draws power only as needed and provides significant, quantifiable energy savings. Demand on cooling systems and expenditures related to hydraulic oil and filters, oil clean-up and disposal are reduced. Combined with the exceptional precision repeatability and cycle time optimization of these machines, the result is less cost and higher yield for improved overall productivity.

Several innovative features, unique to Sumitomo, can also be found in the SE-HDZ:

  • Double Center Press Platen that ensures superior surface pressure balance even in the center surface area of the mold
  • New twin-cylinder high contact force 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

The SE-HDZ is backed by Sumitomo’s comprehensive Customer Satisfaction Program which includes the industry’s best warranty program, worry-free parts, responsive field service and financing availability — plus other important advantages such as 3 days free in-plant training for new customers.
