It uses mechanical force to press the heated and softened rubber
material through a mold, shaping it into the required sealing ring.
The sealing rings produced by this equipment feature high -
dimensional accuracy and good appearance quality. It is suitable
for the production of rubber sealing rings in various shapes and
sizes.
The rubber material is heated and plasticized, and then injected
into the mold cavity through an injection device. It cools and
solidifies in the mold to form a sealing ring. With high production
efficiency, it can achieve automated production, making it suitable
for mass - producing high - precision rubber sealing rings.
Mainly used for producing tubular or strip - shaped rubber sealing
rings. The rubber material is extruded through the rotation of the
screw in the extruder and passes through the die for shaping. After
that, it goes through cooling and setting processes to obtain the
finished product. The extrusion molding machine has a high
production efficiency and can produce continuously, being suitable
for producing rubber sealing rings with relatively single
specifications.
It is used to cut the rubber material into the required blank of
the rubber sealing ring according to certain dimensions and shapes.
Some advanced shearing machines are also equipped with an
adjustable surrounding pressing and placing mechanism, which can
efficiently stack and arrange multiple cut rubber sealing rings,
improving production efficiency and neatness.
Semi - automatic or fully - automatic sealing ring assembly
machines use advanced mechanical structures and intelligent control
systems to accurately position, grasp, and install the sealing
rings. This can effectively avoid deviations and errors that may
occur during manual assembly, improving assembly efficiency and
quality.
The rubber material is placed in the heating chamber of the making
machine or heated by a heating device. Under appropriate
temperature and time, the rubber material softens and becomes
plastic, facilitating subsequent forming processes.
Through molds, extrusion heads, injection devices, etc., pressure
is applied to the softened rubber material, causing it to fill the
mold cavity or take shape through the extrusion head. For example,
in a compression molding machine, the upper and lower molds close
to press the rubber material into the shape of the mold cavity; an
injection molding machine injects the heated and plasticized rubber
material into the mold for forming; an extrusion molding machine
extrudes the rubber material from the extrusion head to form a
continuous tubular or strip - shaped sealing ring.
The formed rubber sealing ring needs to be cooled in the mold or a
cooling device. When the rubber material returns to room
temperature, its shape is fixed, completing the manufacturing of
the sealing ring.
It provides power for the making machine, such as motors, hydraulic
pumps, etc., driving the movement and operation of various
components. Commonly, there are two methods: hydraulic drive and
mechanical drive.
It consists of heating elements, temperature controllers, etc. It
is used to heat the rubber material to the temperature required for
softening and forming. Heating elements usually include electric
heating wires, heating plates, etc., and the temperature controller
can precisely control the heating temperature.
Including molds, extrusion heads, injection devices, etc., it is
the core component of the rubber sealing ring making machine,
determining the shape, size, and accuracy of the sealing ring.
Composed of an electrical control cabinet, PLC controller,
operation panel, etc., it is used to control the operating
parameters of the making machine, such as temperature, pressure,
speed, time, etc., realizing the automated operation and monitoring
of the equipment. Operators can set and adjust various parameters
through the operation panel, and the PLC controller controls the
actions of various components according to the preset program.
Generally, it adopts air - cooling or water - cooling methods to
cool the formed rubber sealing ring and make it set quickly. The
air - cooling system blows cold air onto the sealing ring through a
fan, while the water - cooling system removes heat through
circulating water.
It is used to transport the rubber material to the heating chamber
or forming system. Common ones include hoppers, conveyor belts,
etc. Some advanced feeding devices also have a metering function,
which can accurately control the amount of rubber material added.
It can produce rubber sealing rings with high - dimensional
accuracy and regular shapes, meeting the strict requirements of
different industries for sealing rings, such as the automotive,
aerospace, etc. fields.
With a high degree of automation and fast production speed, it can
complete the production of a large number of rubber sealing rings
in a short time, improving production efficiency and reducing
production costs.
The equipment has a solid structure and stable operation, capable
of continuous operation for a long time, ensuring the continuity
and consistency of production.
According to different production needs, different molds can be
replaced or process parameters can be adjusted to produce rubber
sealing rings of different specifications, shapes, and materials.
