Sumitomo (SHI) Demag’s El-Exis SP (Speed-Performance) is the ultra-high-speed hybrid series of injection molding machines that redefines high productivity for packaging and other thin-wall applications requiring high injection speeds, ultra-fast cycling and exceptional precision.
Available in model sizes from 169 to 1124 U.S. tons, the El-Exis SP has been designed for high-speed production of applications such as thin-wall food packaging, closures for beverages, cartridges, plant pots and buckets. Taking a “best of both worlds” approach to injection molding, the hybrid series combines speed and performance with:
Ultra-high-speed injection via hydraulic accumulator and servo-valve
Energy-efficient electric screw drive for maximum plasticizing capacity and melt homogeneity, and a clamping unit with AC servo drive and hydrostatic transmission for fast, energy-efficient mold open/close
Some of the design improvements for the Speed-Performance series include:
Up to 30% more energy-efficient operation than other high-speed hybrid designs
30% increase in injection speed over predecessor El-Exis S model, achieving up to 1000 mm/sec dependent on configuration
25 millisecond acceleration from 0 to an injection speed of 800 mm/s
A position-regulated servo valve in combination with a high-resolution path measuring system that supports precise and rapid deceleration
Expanded opening stroke for models 330 U.S. tons and above to meet requirements for molding deeper containers such as buckets
The NC5 plus control which has been redesigned with unique functions for high-speed operation and optimization of energy use
