Types of Blow Molding Machines:
Extrusion Blow Molding (EBM) – Produces hollow parts by extruding a molten plastic parison into
a mold and inflating it with air.
Injection Blow Molding (IBM) – Combines injection molding and blow molding for high-precision
containers (e.g., medical bottles).
Stretch Blow Molding (SBM) – Used mainly for PET bottles, where preforms are stretched and
blown into shape.
Multi-Layer Blow Molding – Produces bottles with multiple layers (e.g., for barrier
protection in food & beverage packaging).
Features:
a) The extruding device is equipped with a variable frequency motor
to meet the rotation change requirements of the screw during the
blowing process. A screw with a high slenderness ratio can process
various materials with strong plasticizing ability, high production
capacity, and low energy consumption. The barrel features a
resistance heater controlled by a computer for rapid, stable, and
uniform heating.
b) Through the installation of different heads in a combined
extrusion system between two extrusion machines, products with a
striped appearance or double layers can be blown.
c) The mould clamping device utilizes a toggle type mechanism and
linear guide. With a double station, the mould platen moves quickly
and steadily for efficient operation.
d) An improved design of the hydraulic oil loop ensures power
saving, rapid operation, and stability.
e) The installation and maintenance of hydraulic elements are
convenient, with a removable and mobile oil tank provided.
f) The entire machine is computer-controlled, with the hydraulic
system featuring double proportional control. It includes fault
automatic alarm, ensuring reliable operation, high automation, and
data storage capabilities for up to 40 sets of moulds.
g) Three operation modes - "Manual", "Semi Auto", "Full Auto" - are
available for selection.
h) The safety door is equipped with both electric and mechanical
safety devices to prevent mould closing in case the safety door
opens, ensuring safe and reliable operation.
i) This machine offers two blowing functions - straight cutting and
oblique cutting.
j) Oblique blowing function.
