Electric SBM unit boosts productivity within a compact footprint, offers cavity flexibility

All-electric, reheat stretch-blowmolding machine supplier Amsler Equipment Inc. (Richmond Hill, ON) now offers a three-cavity unit boasting 50% higher productivity for 2L containers (3600 2L bottles per hour) compared with a two-cavity unit, all within the same compact footprint. It can also run in single- or dual-cavity mode.

All-electric unit delivers 50% energy saving versus hydraulic equivalent.

The L32 machine offers production of up to 40 million bottles per year, and features servo-driven electric stretch rods rather than the pneumatic type, a 30-ton servo-driven mold clamping system and a servo preform indexing system. Neck sizes range up to 48 mm. It employs the same oven configuration as a two-cavity model except that preforms can be spaced closer together, thus offering greater heating and more energy efficiency.

The convertible machine can also be used to run one-cavity and two-cavity molds for production of 5L and 3L containers, respectively. An air-recovery system and hot-fill capability are also available.
 The first commercial unit has been sold to a blow molder in the greater Toronto area. —Stephen Moore
