Processes Used to Create Silicone Extrusions
Silicone extrusions can be produced using various processes. Some of the more
common methods such as liquid injection molding, compression molding, and
transfer molding, and their specific application, are discussed in greater
Liquid Injection Molding (LIM)
LIM involves injecting uncured silicone rubber into a mold cavity, where it is
heated and cured to form a solid silicone rubber part. This process is best
suited for small to medium-sized parts with complex geometries.
This process involves placing a pre-formed silicone rubber billet into a mold
cavity, where it is compressed and heated to form a solid silicone rubber
part. This process is best suited for low volume, high precision parts with
This process is similar to compression molding but involves transferring the
uncured silicone rubber from a pot into a mold cavity, where it is compressed
and heated to form a solid silicone rubber part. This process is best suited
for medium to high volume parts with complex geometries.
Design Variations of Silicone Extrusions
Silicone extrusions come in various designs and types. Solid extrusions, for
example, are used for sealing applications where a watertight seal is
necessary. Sponge extrusions are used to provide cushioning and insulation in
applications such as automotive and aerospace. Co-extrusions, which involve
two or more materials being extruded together, are used for applications where
multiple functions are required. For instance, a co-extruded seal with a rigid
carrier may be used to provide structural support and a watertight seal.
Considerations Regarding Silicone Extrusions
When designing silicone extrusions, several considerations must be taken into
account. For example, environmental considerations for silicone extrusions
include the impact they have on the environment during their production and
disposal. Meanwhile, economic considerations include their cost,
cost-effectiveness, and accessibility. Transportation costs and lead times
must also be factored in when considering the economic viability of using
silicone extrusions in a particular application.
Benefits of Silicone Extrusions
The benefits of silicone extrusions are numerous. They are flexible, which
makes them ideal for use in applications that require movement and
deformation. They are also resistant to extreme temperatures, chemicals, and
UV rays, which makes them ideal for use in harsh environments. Additionally,
they have excellent electrical insulation properties and are non-reactive to
most substances, which makes them ideal for use in the medical industry and
Applications of Silicone Extrusions
Due to these benefits, silicone extrusions are used in a wide range of
Silicone extrusions are widely used in the automotive industry for sealing,
insulation, and noise reduction. They are also used in engine components, such
as gaskets, seals, and hoses, where they must withstand high temperatures and
resist exposure to oils and chemicals.
In the construction industry, silicone extrusions are commonly used for
weather sealing, insulation, and vibration dampening. They are also used in
glazing systems and curtain walls, where they provide a durable and
long-lasting seal against the elements.
Silicone extrusions are used extensively in the medical industry due to their
biocompatibility and resistance to sterilization methods. They are used in
medical tubing, seals, and gaskets, as well as in implantable devices.
Silicone extrusions are used in the aerospace industry for insulation,
vibration dampening, and sealing in high-temperature environments. They are
also used in engine components and fuel systems, where they must resist
exposure to extreme temperatures and chemicals.
Silicone extrusions are used in the electronics industry for sealing and
insulation of electronic components, as well as in cables and connectors.
Food and Beverage
Silicone extrusions are used in the food and beverage industry for sealing and
gasketing applications in equipment and machinery. They are also used in food
processing equipment due to their resistance to high temperatures and
Silicone extrusions are used in the marine industry for weather sealing,
insulation, and vibration dampening. They are also used in marine engine
components, such as gaskets, seals, and hoses.
Silicone extrusions are used in the energy industry for sealing and insulation
in power generation equipment and transmission systems. They are also used in
solar panel and wind turbine applications due to their resistance to UV
exposure and extreme temperatures.
