Extruded rubber seals

Extruded rubber seals are used in a wide range of applications such as automotive and industrial sealing, power transmission, and fluid handling. Extruded rubber seals are made of various materials and composites.

The seals are made from a special type of rubber material that is flexible and elastic. These can be used to seal any number of different types of joints. It is important that you know what type of joint you have before purchasing your seals as there are many different types available on the market today.

When you visit an auto parts store they will be able to help you find the right type of seal for your specific needs. You should make sure that you select an extruded rubber seal that will not retain any moisture inside your vehicle or it could cause rusting on your vehicle’s frame or other metal parts within the car itself.

The most common extruded rubber seal is a simple rubber tube with a metal or plastic lip attached to one end. The lip is placed inside a groove in the moving part, and the tube is compressed by pressure from outside the groove. This type of seal is often used for low-pressure applications such as vacuum systems and refrigeration compressors.

Another common type of extruded rubber seal is a metal bellows with an elastomeric liner inside. These seals are typically used where there are higher pressures involved; they can handle pressures up to 100 psi (700 kPa). They are also used when there are temperature fluctuations that may cause some expansion and contraction of the elastomeric liner – like in automotive engines and transmissions, or heavy industrial equipment such as cranes or hoists.

The main raw material for extruded rubber seals is natural rubber

It has good physical properties and high resistance to abrasion, chemicals and heat. Natural rubber is available in different grades and hardness levels to meet the needs of different applications. The most common grades of natural rubber used for extruded rubber seals are SBR (styrene butadiene) and NBR (natural butadiene). These two types of rubber have good physical properties but they do not provide chemical resistance or heat deflection temperature (HDT) required by some applications.

Some companies use synthetic rubbers such as nitrile, EPDM (ethylene propylene diene monomer), SEBS (styrene ethylene butylene styrene), HNBR (hydrogenated nitrile), FKM (fluorinated ethylene propylene), PTFE (polytetrafluoroethylene) or other elastomers such as polysulfide or epoxy resins to make extruded rubber seals with additional features such as chemical resistance.

There are many types of extruded seal, but they all have similar characteristics in terms of their function, construction and application. In this article we will look at some of the most common types of extruded seals that are used in industry today.

Why reliable extruded rubber seals are important

Extruded rubber seals are produced using extrusion machines and die-cutting machines. The process produces cross sections of various different shapes. The extrusions that result from the manufacturing process are used in various different industries such as marine, manufacturing, and automotive. There are various aims that can be present when extruded rubber seals are used including sealing, noise reduction, reduction in vibration, and decoration.

What are extruded rubber seals used for?

Extruded rubber sealsThroughout the various different industries where extruded rubber seals are employed, they have a variety of different specific uses including:

  • Window and door sealing
  • Door weather stripping
  • Automotive rubber sealing
  • Windshield weather stripping
  • Sponge rubber sealing

These are just a few of the numerous different uses for extruded rubber seals that exist in a wide variety of different industries.

Customizing extruded rubber seals for different uses

Manufacturers can carry out a number of different customizations on the extrusions that they produce. These customizations are dependent on the requirements of the company that is purchasing the rubber seals. The processes that can be carried out by the manufacturers include:

  • Cutting into various shapes
  • Drilling to shape holes
  • Punching holes in extrusions
  • Cutting notches in extrusions
  • Slotting extrusions

Using the process of die cutting means that simple shapes can be turned into custom extruded rubber seals that are ideally suited to the use for which they are required. This is important as uses for these seals are extremely varied.
Extruded rubber seals need to be reliable in order to ensure that the sealing and protection purposes for which they are often used are addressed effectively. Companies that need these seals have to ensure they purchase products from reliable manufacturers in order to ensure their processes, machinery, and equipment are protected, enabling them to perform as effectively as possible.

Extruded rubber seals: Manufacturer & Supplier

Mantova Gomma deals with the production of extruded rubber seals. The extrusion process involves a continuous screw that pushes the material through a die, which forms the part. Each extruder has its own characteristics, such as speed range and temperature capability.

The extrusion process creates a rubber seal with varying degrees of hardness and flexibility depending on how long it is heated during production. The softer it is, the less durable it will be over time. A harder rubber is also more expensive because it takes more energy to heat up during production compared to soft rubber.
