K 2022 marks the global debut of Nissei ASB’s brand-new PM-100 machine for injection molding PET preforms in 18, 24 or 36 cavities. This 100-metric-ton press fits between the company’s existing models with 70-m.t. clamp for eight to 24 cavities and 170 m.t. for 48 cavities. At the show, a model PM-100/111N will mold 13.5-g preforms with 28-mm “Alaska neck” for water bottles in 36 cavities at 14,700 bph.

This machine uses a vertical clamp and three-station rotary table. A complete set of lip cavities at each station permits handling preforms by the neck at every step. Preforms are molded in three rows and are cooled on both inner and outer surfaces. At the eject station, further cooling can occur before ejection from the lip cavities. Two injection screw diameters and two clamp daylight options are available. Footprint is only 13 m2.
