of the same weight, the cycle time was 8.6 sec, vs. 17.45 sec before, for production capacity of 2508 bph, up from 1236 bph. A new AL-500-50 was molding 30-ml PET medicine bottles in 10 cavities on a 3.4-sec cycle or 8370 bph. With the same cavitation and bottle weight, the previous SB III-250LL-50S achieved a 9-sec cycle, for 4000 bph.

For the older SB III-250LL-50S, the comparable figures were 18.1 sec and 1188 bph. The fourth new machine is the AL-1000LL-40, which molded 90-ml HDPE packer bottles in 12 cavities and 9.5 sec. This machine has four times the shot capacity of the SB III-250LL-50S, which could mold the same bottle in only six cavities and 20 sec. The differ- ence is 4536 bph vs. 1080 bph. SIPA of Italy (U.S. office in Atlanta; demonstrated a newly enhanced model ECS SP80 (80-ton) single-stage ISBM system for up to 16 cavities, containers up to 8 L, neck diam. to 110 mm, and outputs up to 7200 bph. This hybrid machine incorporates servo-hydraulic injection and clamping and electric screw drive. The rotary system has four stations, including one for preform conditioning. At the show, a four-cavity system produced four different bottles (around 200 ml) simultaneously on a 14-sec cycle. New features include a quick-mold-change system for short runs that can cut changeover times by about 25%. Jomar's newest servo-hydraulic injection-blow machines have controls designed with Industry 4.0 in mind—for example, remote monitoring of process-data "dashboards" like this one. 42 AUGUST 2018 Plastics Technology NPE WR AP-UP
