Blueline HF series machines, manufactured by STM, feature compact devices, used for manufacture of HOT FILL containers of up to 1.5 l, with 4, 6 or 8 cavities, depending on the model. With the technology used we are capable of manufacturing bottles that can be filled at temperatures up to 88 °C.
Characteristics of the machines are as follows:

  • high efficiency up to 99%,

  • speed per blow mould – up to 1200 bph (depending on expected temperature of the filled media),

  • compact design,

  • low operating costs,

  • high repeatability of bottles,

  • ease of use, with user-friendly interface and extensive controllability,

  • possibility of using low weight preforms (also from rPET)

Most of the machine’s functions are controlled by servomotors; this way the machine runs faster, ismore quiet and consumes 50% less air (10 bar), compared to other designs based on pneumatics. As a standard, STM machines are equipped with ECO Power Innovation System ® that ensures high quality of produced PET bottles, while providing maximum power savings; moreover, a number of options is also available.
