2005 - Sumitomo SHI Demag EL-EXIS S 250 Injection Molding

About this machine

This used Sumitomo SHI Demag EL-EXIS S 250 is an injection molding machine — sometimes referred to as a plastic injection press — a type of industrial equipment used to manufacture precision plastic parts by injecting molten material into a closed mold under controlled pressure. Sumitomo SHI Demag is a well-established name in plastics processing machinery, supplying injection molding equipment to industries ranging from automotive and medical technology to consumer goods and packaging.

Manufactured in 2005 and located in Germany, this machine is offered in used condition, with five similar units available from the same source. It is built to the basic European compliance standard and conforms to the applicable safety regulations in force at time of manufacture.

The clamping unit is equipped with chromed tie bars and features elastic machine mounting for vibration isolation. A reduced centering diameter of 100/125 mm is fitted to the fixed mold platen, and mold connection dimensions follow type E, which is similar to the EUROMAP standard. The machine is configured without a side ejector plate and is set up for standard mold installation height. A safety interlock ensures that mold opening and ejector forward movement are permitted only when the safety door is closed.

A central accumulator supports high-speed injection and also drives core, ejector, and nozzle movements. Injection, holding pressure, and back pressure are all controlled via servo valve, while the ejector operates under position control through a proportional valve, with pressure and velocity independently programmable. Nozzle movement runs parallel to mold movement. The screw drive is electric and frequency-controlled. An ultrasonic displacement measuring system with digital data transmission monitors injection, ejector, mold, and nozzle movements, with a resolution of 1/100 mm on the injection axis.

Electrical supply is 400 V / 50 Hz, three-phase with neutral and protective earth, and the machine provides separate mains connections for the drive and the heating circuits. Pump drive power is rated at 22.0 kW. Cooling is handled by a reinforced oil cooler, and separate water connections are provided for mold cooling and oil cooling circuits. The control system features a color data display with VGA interface and an AT keyboard interface.

The machine is painted in the standard two-tone scheme: bottom sections in anthracite grey RAL 7016, upper sections in blue 571C MD.
