Higher Productivity & Energy Savings for Packaging, Industrial Parts

Among at least six new hardware introductions at the show, Bekum America is highlighting two machines in particular. One is the EBLOW 407D, its first U.S.-built all-electric shuttle. It incorporates mostly domestic components — including the patented C-frame E-Twin Toggle and the seven or more servo motors plus actuators — making availability of spare parts simpler and more reliable.

This midsize, double-sided model is a “four-cavity gallon machine,” having a 15-metric-ton clamp, 520-mm stroke and 500-mm maximum mold width. It’s running (for the first time in public) EPET handleware (2 L, two cavities) to demonstrate that electric machines can handle such a tough application as hard-to-trim EPET.

Another highlight of Bekum’s booth is the brand-new XBLOW 200 industrial machine (200 m.t.), shown here with accumulator head. It can blow 500 L tanks in a single cavity. A key feature is the new clamp design with diagonal tie bars and fast movements due to two-stage action with servohydraulic or hybrid cylinders. (Source: Bekum America)

The second main highlight is a brand-new industrial machine, the XBLOW 200, for containers up to 1000 L. Though not physically present, a video of it in action and a 500-L tank produced on this 200-metric ton machine are on hand. The XBLOW series (announced at K 2022) features a new clamp design with two diagonal tie bars and rapid movements via a long-stroke toggle (servohydraulic or electric) paired with a servohydraulic short-stroke cylinder. This series can have accumulator or continuous extrusion heads.

A brand new continuous-extrusion head, model BKW400-3, is for producing drums and industrial containers up to 250 L on the XBLOW 100 machine. The new spiral-mandrel design is said to provide improved parison concentricity and layer uniformity in tri-layer coextrusion, as well as faster color changes. This head can be part of a three-layer retrofit package for upgrading monolayer machines (at lower cost than buying a whole new machine).

Available as part of the three-layer retrofit, or on monolayer machines, is a new extruder concept that’s already popular for industrial machines in Europe and is catching on here, says Bekum. The key is saving energy with a primary extruder of smaller diameter and longer L/D. For example, a 60-mm, 36:1 extruder is said to have the same length and output capacity as a 90-mm, 24:1 unit, while using 18-20% less energy.

Pictured at the booth is Bekum’s 08 series of all-electric shuttles, introduced at K 2022. These have spiral-mandrel heads and C-frame clamps in 6 to 50 metric tons; some have extra-long strokes greater than 1 meter. Designed for quick mold changes, they also introduced the new BC 8.0 controls — now standard on all new Bekum machines.
