Injection Molding: High-Speed All-Electric Press Line
Designed for packaging with cycle times of 3 to 10 sec.
At October’s Fakuma 2018 show in Germany, Sumitomo (SHI) Demag introduced the all-electric, high-speed IntElect S series from 50 to 180 metric tons, with injection speeds between 350 and 500 mm/sec. They are built especially for cycle times in the 3- to 10-sec range, vs. >10-sec cycles for standard IntElect machines, which have injection speeds of 50 to 200 mm/sec. To accompany the new high-speed range, Sumitomo Demag launched the SDR Speed robot series, built by Sepro.
Starting last year, the company renewed the standard IntElect line with a second-generation series and a new platen concept. This started at the small end with machines from 50 to 180 m.t. Mid-size models up to 500 m.t. will follow next year. Larger IntElect S models are also planned.
What it means. Why it's important.
One of the more prominent trends in processing is the need for higher plastic pressures to mold parts.
Most molders work with two parameters for establishing second-stage pressure. But within Scientific Molding there are actually four.
