High-Contact Force (Nozzle Touch) System

Sumitomo (SHI) Demag SE-HSZ and SE-HDZ all-electric injection molding machines are equipped with a twin-cylinder high-contact force system that provides significant advantages over lower contact force systems. These advantages include:

• High force (6.61 tons) comparable to that of a hydraulic clamp machine for high-precision control under high injection pressures


• Dual pull-in rods design for protection of molds and sprue bushings


• Exceptionally fast pressurization/ depressurization of 0.3 seconds for faster cycle times. (Typical times range from 0.6 to 1.0 seconds and thus this feature can reduce cycle time by up to 1.4 seconds.)

Additionally, the nozzle touch can be remotely preset to 4.4, 5.5 or 6.6 tons to ensure compatibility with cold runners, hot runners and floating sprue bushings.
