Description:
Plastic
Supporting
Core
Plastic
supporting
core
is
a
spiral-structured
supporting
component
specially
designed
to
support
and
expand
various
rubber
products
such
as
rubber
tubes,
rubber
sleeves,
cold-shrink
tubes
and
other
rubber
fittings.
As
a
key
auxiliary
part,
plastic
supporting
core
provides
stable
and
lasting
expansion
force
to
keep
rubber
parts
in
an
open
and
expanded
state,
which
is
convenient
for
installation,
transportation
and
later
application
in
power
and
telecom
projects.
Made
of
high-quality
PP
or
PE
raw
materials,
this
plastic
supporting
core
features
high
structural
strength,
good
toughness
and
stable
physical
properties,
ensuring
long-term
use
without
easy
breakage
or
deformation.
The
whole
plastic
supporting
core
is
processed
by
mature
spiral
forming
technology,
with
uniform
stress
distribution
and
excellent
matching
performance
with
rubber
parts.
In
addition
to
being
used
as
an
internal
support
for
rubber
components,
plastic
supporting
core
can
also
be
machined
and
assembled
into
handles
for
hardware
tools,
bicycle
grips,
hand-held
equipment
and
other
daily
and
industrial
products,
realizing
multi-scenario
application.
Plastic
Strip
Plastic
strip
is
the
special
raw
profile
for
manufacturing
plastic
supporting
core.
Made
of
PP
or
PE
material,
it
is
the
basic
semi-finished
product
for
forming
spiral
plastic
supporting
core
of
different
diameters.
Through
automatic
spiraling
equipment,
the
plastic
strip
can
be
processed
into
standard
or
customized
plastic
supporting
core
efficiently
and
stably.
It
is
compatible
with
auto-buckled
and
welding
processes,
which
can
realize
continuous
automatic
production,
with
high
welding
joint
strength
and
not
easy
to
deform
after
forming,
laying
a
solid
foundation
for
the
stable
quality
of
it.
Product
Application:
1.
Plastic
supporting
core
is
mainly
used
as
an
inner
supporting
and
expanding
part
