At the recent K 2022 show, 1Blow of France introduced a model of its very compact all-electric reheat stretch-blow machines for bottles up to 12 liters (3 gal). The new 2XL machine is the company’s first two-cavity system for bottles of this size, while retaining a small footprint of only 6.5 x 8 ft. (Previous models could mold a single container of 12 L or even up to 30 L.) It handles neck finishes up to 53 mm and outputs up to 3800 bph for 0.5 L, 9-g bottles. Optional technology kits include preferential and offset neck heating, neck orientation, heat-set/hot-fill and Sure Grip molded-in handle.
In keeping with the overall “green” theme of K 2022, 1Blow emphasized the low energy consumption of its reheat stretch-blow machines under the new label “GreenBlow.” Among the energy-saving features of this all-servo design are recovery of braking energy on the five servomotors to power the next motion; recovery of high-pressure blowing air to furnish 100% of the machine’s low-pressure air requirement; and “SuperVenting” mold technology (supplied by a moldmaking partner) that allows bottles to be blown with a little as 300 psi vs. the conventional 600 psi, reportedly saving 30-40% in energy.
