Used Blow Molding Machine Terekas up to 5L 1000 bph This used blow
molding machine from Terekas, model FlexBlow 1, is designed for
demanding PET bottle production, offering advanced flexibility and
efficiency. With a maximum bottle capacity of up to 5 liters and a
throughput of up to 1,000 bottles per hour, the system is engineered
for operations that require consistent product quality across multiple
neck finishes and formats. The FlexBlow 1 utilizes a linear blow
molding architecture, equipped with a single cavity, making it ideal
for short production runs, frequent changeovers, or pilot lines. It
integrates seamlessly into existing filling and packaging lines,
thanks to its modular design and compatibility with multiple container
types. The preform feed system includes a tipper, unscrambler, and
loader, all designed to ensure reliable, jam-free supply of preforms
into the production cycle. The core of the process begins with a
robust preform heating tunnel, employing infrared (IR) lamps enclosed
within a secure, ventilated housing. Preforms are conveyed through the
heating zone by an articulated chain system, which ensures precise and
uniform exposure to the heat source. The IR heating zone is shielded
by a protective grid, preventing accidental contact while maintaining
optimal thermal consistency across the preforms. The tunnel design
avoids excessive hot spots or thermal degradation of the preform,
contributing to higher end-product quality and reduced scrap rates.
Precise Control and Reliable Operation After exiting the heating
tunnel, preforms are transferred automatically into the blow molding
station. The FlexBlow 1âs single-cavity blow unit utilizes
high-efficiency pneumatic actuators and robust mold clamping
mechanisms to produce containers up to 5 liters in volume. This
configuration allows for rapid cycling and excellent pressure control
throughout the stretch-blow sequence. The complete air handling system
is engineered for reliability, with integrated air recovery to
optimize compressed air consumption and reduce overall utility costs.
Critical to the systemâs operation is the dedicated chiller,
which ensures mold cooling circuits remain within the required
temperature range, guaranteeing consistent bottle wall thickness and
minimizing cycle times. All pneumatic and hydraulic components are
mounted in a well-organized auxiliary area, with clearly labeled
connections for maintenance and diagnostics. Filtration and
lubrication points are readily accessible, supporting a high level of
system uptime and minimizing unscheduled stops. Machine operation and
process parameters are managed through a touchscreen HMI panel
installed directly on the electrical cabinet. This interface provides
real-time control over all production settings, alarm management, and
maintenance prompts. The entire machine is wired in a highly organized
manner, with secured electrical panels, neatly routed cables, and
clearly identified terminals for ease of troubleshooting. All safety
guards and interlocks are present and functional, ensuring the
operatorâs safety while maintaining accessibility for service
interventions. Versatility in Container Formats and Ease of Changeover
A major advantage of the Terekas FlexBlow 1 blow molding machine is
its capability to handle a wide range of neck finishes and preform
geometries. Supported neck types include 24/410, 25mm Snap On, 28/410,
28mm ROPP, 38SP400, 38mm 2-Start, 38mm 3-Start, and 53SP400. This
broad U6354234 compatibility allows the system to produce bottles for
a diverse set of applications, from standard beverage packaging to
specialty food, household, or personal care containers. Changeover
procedures are simplified by a fast-format-change mechanism, enabling
the operator to quickly adapt the machine to new preform sizes or
bottle formats with minimal downtime. The mechanical components,
including preform guides, grippers, and neck holders, are engineered
for tool-free adjustments where possible, supporting both efficiency
and repeatability. The blow molding cavity, heating tunnel, and
preform handling system are all designed for rapid and reliable
adaptation to varying production demands. With a total production
record exceeding 20 million bottles, the FlexBlow 1 demonstrates
proven durability and reliability in continuous industrial
environments. Regular maintenance procedures are supported by
comprehensive manuals and technical documentation provided with the
machine. Spare parts compatibility is assured, as key mechanical and
electrical components are based on industrial standards. The blow
molding system includes a complete preform handling line: a tipper
allows bulk loading of preforms, which are then separated and aligned
by the unscrambler before entering the loader. This ensures continuous
feed into the oven and uninterrupted production cycles. The integrated
compressor and air management modules are dimensioned for the
machineâs maximum rated output and are equipped with
