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 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
