Sumitomo Demag will make the North American debut of its El-Exis SP hybrid series of injection molding machines at NPE2012 (booth #2103).
The company will demonstrate two model sizes of its El-Exis SP.
"Greeting visitors to the West Hall will be a full in-mold labeling cell that features complete coverage of the plastic surface using a unique process developed by Marbach moulds and automation GmbH," Jim Mitchell, executive vp of Sumitomo Demag in a news release. "With this process, barrier functions and full-graphic cover labeling can be integrated in the packaging process."
Available in model sizes from 165 to 825 tons, the El-Exis SP has been designed for high-speed production of applications such as thin-walled food packaging, closures for beverages, cartridges, plant pots and buckets.
The hybrid series combines speed and performance with high speed injection via hydraulic accumulator and servo-valve, as well as an energy efficient electric screw drive for maximum plasticizing capacity and melt homogeneity. The clamping unit has AC servo drives and hydrostatic transmission for energy-efficient mold open/close, according to the company.
Some of the design improvements for the SP series include up to 30% more energy efficient operation than other high-speed hybrid designs, and up to a 30% increase in injection speed over previous El-Exis S models, achieving up to 1000 mm/sec dependent on configuration,.
"The El-Exis SP raises the bar for overall productivity in high-speed and thin-wall applications," said Mitchell. "This degree of overall productivity even provides a cost-effective IM solution for some packaging applications that may have previously been reserved for thermoforming."
Together with Marbach molds and automation GmbH (booth #223), Sumitomo Demag will demonstrate the manufacture of thin-walled containers with full-cover labeling. A special feature of Marbach's IML process is that the banner label and the base label are inserted overlapping around a radius, thereby providing complete coverage of the plastic surface with the label reaching up to a high level on the sealing edge. In this way, barrier functions can be integrated into the packaging by means of labels.
For the demonstration, a Marbach double-cavity IML hot-runner mold will run on an El-Exis SP. The compact production cell manufactures the 250 g containers from PP (final weight 14.2 g) in a cycle time of approximately 3 seconds. The highly precise mold stop position of the El-Exis SP ensures the exact positioning of the labels despite the high production speed, the company stated. |
