Blow Moulding
is one of the fastest growing divisions of the Plastic Industry
and our philosophy is to support this growth by providing the
best technology at the best price. Our cost effective and
innovative technology is best revealed by the results and
encouragements throughout the world.
Blow molding is the process of forming hollow products by
expanding a hot plastic parison against the internal surfaces of
a mold. Different blow molding processes offer different
advantages, based on the material used, performance
requirements, production quantity, and costs.
Plastics are used to fabricate a wide range of blow molded
parts, including small bottles for household products and
personal care, dairy products and carbonated drinks, small
containers for industrial goods or chemicals, fuel tanks, jerry
cans, large tanks, drums, and car dashboards. We provide
complete turnkey project inclusive of plastic ancillary
equipment like chillers, cooling towers, grinders, recycling
plants etc.
Continuous extrusion blow molding:
In the continuous process, a stationary extruder
plasticizes and
pushes molten polymer through the head to form a continuous parison. For large part blow molding, accumulators are used to
prevent sagging of the parison.
Intermittent blow molding:
In the intermittent process, the melt is accumulated in the
barrel and pushed out in one shot. Intermittent blow molding is
used, amongst other applications, in the fabrication of dairy
bottles, because of its high production speed.
Coextrusion blow molding:
Coextrusion blow molding makes it possible to combine materials
with different properties to create a finished product most
suitable for a particular application. This process can be used
to fabricate products which contain several layers in their wall
structures. The various parts of the structure can be optimized
for the best balance between properties and cost.
Injection blow molding:
Injection blow molding starts with an injection molded pre-form,
which is then reheated, and blown into its final shape in a
mold.
Injection stretch blow molding:
Injection stretch blow molding starts with an injection molded
pre-form which is reheated, and stretched with a pin while
simultaneously being blown in a mold. This conversion process is
typically used to produce PET bottles.
3-D blow molding:
3-D blow molding is a recent development in which a robot arm is
used to position the parison in a three-dimensional mold, prior
to being blown. Advantages are low trim-off, and the ability to
produce complex shapes. It is typically used to produce
automotive parts.
