Rubber gaskets and seals are vital components used
in a multitude of applications to prevent seepage of
moisture or air. Qualiform
is the source for custom manufactured rubber gaskets
and rubber seals. No matter what application,
Qualiform has the experience to solve a variety of
sealing problems. We provide a comprehensive line of
commercial and specification grade elastomers to
fabricate a variety of rubber parts including:
-
Rubber Gaskets
-
Rubber Seals
-
Rubber Washers
Qualiform has the resources to assist you in
developing new designs and selecting materials and
processes. Qualiform's technical staff considers
many factors in the design process and recommend the
best method to meet our customers' quality and cost
requirements. For large or small runs, our
manufacturing capabilities mean a prompt response to
your sealing needs.
There are two separate stages in the life of a
gasket or seal:
-
Its primary fit and function.
-
Its ability to endure its environment.
Qualiform knowledgeable staff considers such factors
in the design stage of rubber gaskets, so they will
not be the weakest link among all components in a
product. Environmental factors to consider in
gasket or seal application are:
-
Flammability - UL specifications, heat resistance
-
Function - the motion acting upon it
-
Impermeability - exposure to gases
-
Organic materials - fungus resistance, odor,
tastelessness
-
Temperature extremes - heat, cold
-
Weather - water, ozone, sunlight
Seal types
Static Rubber Seals
Where there is little or no motion of assembly parts
on the seal.
An initial compression or intervallic compression
(open and close) characterizes this type of seal:
-
A
liquid seal in a hose joint
-
A
door seal on a home
With use of a Static Seal, compression pressure
operates in a vertical direction relative to the
face of an O-ring or face gasket and constricts two
different surfaces to eliminate gaps.
Dynamic Rubber Seals
Where there is repetitive motion of assembly parts on
the seal.
Repeated actions on the seal, recurrent or
intermittent, characterizes this type of seal:
-
A
shock absorption device
-
A
piston ring seal
Dynamic Seals are more complex than static seals
because of the varying stress levels. In addition to
Static Seal considerations, Qualiform engineers
assess abrasion resistance because it is affected by
the companion surface finishes. Other considerations
include: compression set, temperature changes,
thermal cycling, distortion, recovery speed after
compression, physical strength, tensile strength and
tear resistance. Qualiform engineers asses all of
these environmental forces and provide the most
efficient and cost effective methods to meet our
customers' quality and cost requirements.
