Large Electric Shuttle for Coextrusion with PCR
At K 2022, Plastiblow showed the new all-electric PB50ES-1000 Coex3 machine making three-layer, 20 L jerrycans with PCR in the center layer.

At the recent K 2022 show in Düsseldorf, Plastiblow of Italy (represented here by Globeius) introduced what it calls the “all-new” model PB50ES-1000 Coex machine for three-layer coextrusion blow molding with post-consumer recycle (PCR). The all-electric, continuous-extrusion shuttle has a 50-metric-ton (55 U.S. ton) clamp and 1000-mm stroke (a model with 1300-mm stroke is also offered). The largest size of the company’s all-electric shuttles, it comes with “Industry 4.0 ready” controls that allow for remote monitoring and diagnosis.
At the show, the machine made stackable 20-liter HDPE jerrycans in two cavities with three layers, the center layer of PCR. The single-sided machine has a maximum output over 240 jerrycans/hr, which can be doubled in a model with two heads and two stations. The machine on display had three horizontal extruders, one of 100-mm diam. for the center PCR layer and two of 80-mm for the inner and outer layers. The dual three-layer coex head had a 200-mm die and 400-mm center distance with dynamic PWDS ring device for parison thickness control and radial optimization. The two-cavity mold had a movable bottom section, driven by electric servomotors.
