Extrusion system
Our plastic bottle molding machines are fitted with an extrusion
system that represents the pinnacle of modern engineering. The
automatic temperature - controlling device, sourced from a world -
leading brand, is the beating heart of this system. In the
extrusion process, plastic materials undergo a complex
transformation from solid pellets to a flowing, malleable state.
Precise temperature regulation is not just an advantage; it's a
necessity. Different polymers, such as the widely used PET for
clear beverage bottles or HDPE for durable detergent containers,
have unique melting points and processing windows.
The state - of - the - art temperature controller offers an
accuracy that is second to none, with a tolerance of ±0.3°C in
premium models. This remarkable precision ensures that the plastic
is in an ideal molten state as it approaches the extrusion die. For
instance, in the production of high - end pharmaceutical bottles,
where even the slightest variation in material properties can
impact product integrity, this level of temperature control is
indispensable. Any deviation from the optimal temperature can lead
to issues like inconsistent melt flow, which may result in uneven
wall thickness in the final bottle.
Driving the screw is an innovative electromagnetism motor reducer,
a technological marvel that enables seamless stepless regulating.
This feature empowers operators to fine - tune the extrusion
process with unprecedented precision. When working with a viscous
engineering plastic, such as polycarbonate used in safety -
critical applications, a higher torque can be dialed in to push the
material through the die. Conversely, for less viscous materials
like LDPE used in lightweight packaging, a lower torque and higher
rotational speed of the screw can be selected. This adaptability
not only enhances the quality of the extruded plastic strands but
also significantly boosts the overall productivity of the machine.
Clamping device
The clamping device in our machines is a masterpiece of design,
featuring a bi - directional synchronous clamping mechanism with a
double - axis single - cylinder configuration. This setup is
engineered to provide rock - solid stability during the plastic
bottle molding process.
During the injection and molding phases, the molds must be held
together with utmost precision. The bi - directional synchronous
clamping ensures that the clamping force is evenly distributed
across both the horizontal and vertical axes. This is crucial
because any imbalance in force can cause misalignment between the
mold halves. Such misalignment can lead to a host of defects in the
final product, including uneven wall thickness, flash (excess
plastic around the edges), and distorted shapes. The double - axis
design further enhances the stability by providing a more uniform
clamping action.
The single - cylinder, despite its uncomplicated appearance, is a
powerhouse. It is capable of generating substantial clamping
forces, making it suitable for handling molds of various sizes and
complexities. When manufacturing large industrial drums, which
require a significant amount of force to keep the molds tightly
closed during the injection of molten plastic, our clamping device
rises to the occasion. It not only ensures that the plastic is
properly shaped but also extends the lifespan of the molds by
minimizing wear and tear caused by uneven stress distribution.
Blowing device
Our plastic bottle molding machines are equipped with an upper -
blowing type blowing device, a design that offers several distinct
advantages in the production of plastic bottles.
When the molten plastic pre - form is ready to be transformed into
a bottle, the upper - blowing mechanism takes center stage. This
method allows for a highly controlled and uniform distribution of
air pressure. The result is a more even expansion of the plastic,
leading to bottles with consistent wall thickness and flawless
shapes. In the production of delicate cosmetic bottles, where
aesthetics and functionality are equally important, the upper -
blowing device shines. It can precisely shape the intricate neck
and shoulder areas, ensuring a perfect fit for caps and pumps. The
air being directed from the top gives operators greater control
over the shaping process, reducing the risk of imperfections.
Compared to other blowing methods, the upper - blowing type
significantly reduces the likelihood of air pockets or uneven
inflation. In traditional blowing techniques, air distribution can
be uneven, leading to thin spots or bulges in the bottle walls.
Additionally, the upper - blowing design is more energy -
efficient. It requires less air pressure to achieve the desired
bottle formation, which not only cuts down on energy consumption
but also lowers operational costs.
Hydraulic system
The hydraulic system in our plastic bottle molding machines is a
paragon of reliability and performance, incorporating world -
famous brand controlling components and a sophisticated
proportional controlling circle.
The use of top - quality controlling components is a testament to
our commitment to delivering a machine that can withstand the
rigors of continuous industrial use. These components, including
valves, pumps, and actuators from renowned manufacturers, are
designed to operate flawlessly under high - pressure conditions.
The world - class build quality ensures minimal leakage and long -
term durability, reducing the need for frequent maintenance and
downtime.
The proportional controlling circle is a key differentiator of our
hydraulic system. It enables operators to precisely control the
hydraulic flow and pressure. For example, during the injection
process, the proportional control can rapidly adjust the hydraulic
pressure to ensure a quick and complete filling of the mold. When
the machine switches to the mold - opening and - closing phase, the
pressure can be carefully modulated to prevent any damage to the
molds. This level of control not only optimizes the efficiency of
the machine but also significantly improves the quality of the
plastic bottles produced. By fine - tuning the hydraulic system, we
can reduce cycle times and increase overall productivity.
Electric controlling system
Our plastic bottle molding machines are equipped with an advanced
electric controlling system, with a programmable controller from
B&R Austria at its core. B&R, a global leader in industrial
automation, brings a wealth of innovation and intelligence to our
machines.
The programmable controller is highly adaptable and can be
customized to manage every aspect of the machine's operation. From
the moment the machine is powered on, it undertakes a comprehensive
self - diagnostic sequence, checking the status of all components
to ensure a smooth start - up. During production, it coordinates
the seamless operation of the extrusion system, clamping device,
blowing device, and hydraulic system. If there is a change in
production requirements, such as a switch to a different bottle
size or a new plastic material, the programmable controller can be
easily reprogrammed to adapt.
Every electric component in the system is sourced from world -
famous brands, guaranteeing consistent performance, reliability,
and compatibility. The motors, sensors, and relays work in harmony
to provide a stable and efficient operation. The sensors, in
particular, play a crucial role by accurately detecting various
parameters such as temperature, pressure, and position. They
provide real - time feedback to the programmable controller, which
then makes instant adjustments to maintain optimal operating
conditions. For example, if the temperature in the extrusion barrel
begins to deviate from the set point, the controller can
immediately adjust the heating or cooling elements to bring it back
to the desired temperature. This ensures the consistent production
of high - quality plastic bottles.
