1. What Is Rubber Extrusion?

Rubber extrusion is a method of producing parts.

Rubber-Extrusion parts

To give synthetic or natural rubber materials their section profile, a high-pressure extrusion machine drives them through a specified die.

This allows them to form or cut throughout this process into a shape. This method is mostly utilized in the production of rubber goods.

A high-pressure extrusion machine is used to drive synthetic or natural rubber material through a forming die.

The most common material is soft, unvulcanized rubber.

The workpiece is first shaped in a soft, flexible state before being vulcanized to harden it into a useful end product.

Extruded rubber goods are light, flexible, long-lasting, and exceptionally durable.

These parts are also appropriate for a tough or extreme condition, such as in high-temperature environments or applications with a lot of chemicals.

The continuous rubber extrusion technique can create parts in a wide range of lengths and forms at a reasonable cost and with minimal waste.

2. How Rubber Extrusion Process Works?

The process of rubber extrusion starts with a standard rubber extruder.

The manufacturers start with a design phase where they have to make the choices for die and material for manufacturing.

Then the process follows as under.

  • For hot extrusion, it starts by pre-heating the stock until it is molten.
  • If this stage is skipped, it means the process of “cold extrusion” or “cold feed extrusion” is going on depending on the application.
  • Then, the hopper is filled that is hung above the conveyor with unvulcanized rubber.
  • The rubber stock is then gravity-fed back through the hopper’s bottom and onto the conveyor.
  • The rubber is moved towards the die by a conveyor and a rotating screw.
  • The screw generates pressure and heat, which aids in the movement of the rubber.
  • The rubber swells and takes on its shape when it goes through the die’s aperture once it has reached the end of the conveyor and has softened sufficiently.
  • After passing through the die, the rubber emerges from the other side of the extruder with a formed profile that fits the die.
  • After processing the rubber, the next step can be vulcanization, coiling, dusting, cutting, splicing, drilling, and taping end joining.

3. What Are Rubber Extrusions Used For?

Rubber extrusions are the products that are frequently used in sealing applications such as doors and windows, weather stripping, and draught excluders.

Rubber-Extrusion tube

They are also used for D-fenders on ships. Extrusions can be anything from simple geometric shapes to intricate dual-material seal designs.

Rubber extruders produce a variety of shapes and items that are useful in everyday life.

They are used in extruded rubber seals, bumpers, rubber grommets, rubber floor matting, connectors, and more.

Rubber extrusions are regarded as sealants and gaskets in general because of their great flexibility, impermeability, and robustness.

Even the eraser that is placed on the end of a pencil is made of them.

Rubber extrusions are utilized in automobiles, bicycles, space shuttles, and submarines, among other places.

4. What Are The Benefits Of Rubber Extrusion?

Rubber extrusion process is helpful and beneficial for providing high quality goods in a variety of shapes and lengths.

Rubber extrusions have a number of advantages. Manufacturers can make unique goods by using high-quality rubber and blending compounds.

Extruded rubber goods are light, flexible, long-lasting, and exceptionally durable.

Chemicals, heat, cold, age, fatigue, friction, abrasion, and wear and tear do not affect them.

They’re perfect for a variety of severe or demanding environments.

These items meet a variety of requirements, including resistance to potentially hazardous operating conditions such as:

  • Abrasion
  • Cold
  • Wear and tear
  • Color fade
  • Friction
  • Aging
  • Heat
  • Fatigue

5. What Are The Types Of Extruded Rubber Profiles?

Extruded rubber profiles can have various shapes starting from a simple design to a U shape.

In some cases, they are multidimensional, multifaceted geometries with exquisite detailing.

The profile means the shape of the rubber that is finalized for an extruded rubber product.

It is also used for a cross-section of the die that is used in the process of rubber extrusion.

Profiles made of extruded rubber include:

Round cord

A round cord is made using Neoprene, EPDM, or Nitrile material mostly. This allows providing a good round shape profile to the product.


Some extruded rubbers are formed into a square shape based on their type of use that gives them a square profile formation.

D-, P-, e-, J-, L-, and T-

The L and T-shaped rubber extruded profiles are very common among them all.

These are used information of a connection or providing a link between two connections.

The D and P-shaped rubber extruded profiles are the types of rubbers that are used for high-end purposes.

U Channels

U Channel Shaped profile of rubber gives it a roundabout look and its specific use in the field.

Half-round profiles

The half-round extruded rubber profiles play a major role in a center formation of a connection.


The rectangular extruded rubber-shaped profile gives a complete connection of the material of the purpose.

6. What Are The Different Materials That Can Be Used For Rubber Extrusions?

There are some important materials that are used in rubber extrusions, and each of them is discussed below.

Rubber-Extrusion material

Natural Rubber

Natural rubber, also known as gum, is popular for its excellent acid and abrasion resistance.

This material is highly used in rubber extrusion.

Silicone rubber

Silicone rubber is also another material used in rubber extrusion because it is an FDA-approved non-reactive elastomer.

It is chemically inert and no longer reacts with organic liquids.

In addition, it retains its shape and housing while exposed to excessive coffee and temperature.

Silicone is known for its advanced properties in food and healthcare conveyor belts.


Another material used in rubber extrusion is Viton. The heat, chemical, and weathering resistance of this rubber composition are exceptional.


Because nitrile, a synthetic rubber copolymer, is oil-resistant, it is utilized to create rubber items that will come into contact with oil, such as hoses, O-rings, and hydraulic seals.


Ethylene propylene diene terpolymer is resistant to heat, ozone, oxidation, aging, and UV light, among other things.

Sponge rubber, door gaskets, window gaskets, foam rubber, weather-stripping, and roofing are just a few of its uses.


Neoprene is a great material that is resistant to fire, UV radiation, heat, water, and grease.

It has high tensile strength as well, which makes it a useful material for rubber extrusion.


Butyl is also useful material because it has properties that allow a limited permeability to airflow.


SBR is a highly abrasion-resistant material which makes it an excellent material to be used in the manufacturing process.

As a result, it’s used in a wide range of automotive applications, including motor mount and belt cover construction.

7. What Are The Applications Of Custom Rubber Extrusions?

Rubber extrusion is most manufacturers’ preferred rubber processing technology because it allows for great levels of customization.

It helps to produce products with superior consistency and robustness. The applications of custom rubber extrusion are.

8. What Factors To Consider Before Buying Rubber Extruded Products?

When you want to buy rubber extruded products, you need to be aware of the following important factors.

different shape Rubber-Extrusion parts

Selecting the Right Material

It’s important that the rubber extruded product that you want to buy must meet the quality standards for the open market.

This is the reason that you need to select the right material products for your business.

The rubber extrusions that are made from neoprene, Viton, natural rubber, or silicone are the best options to consider.

Design Of The Product

It is always a smart thought to select a rubber extrusion product with a small radius.

This is because a sharp corner or 90 degrees may give a sleek look to an extrusion, but it is impractical, and it mostly causes to leak.

It’s an important factor to consider because rubber extrusions mostly have to deal with sealing surfaces.

Ask Recommendation From Supplier

As your supplier is manufacturing all the products, it’s a good thought to ask their suggestion for your rubber extrusion product choice.

Their experience level and expertise in the field will allow them to give you the best option suggestion for your ease.

Cutting Technique

The cutting technique is one of the crucial factors to consider in rubber extrusions.

There are various ways to cut the rubber materials, which is why you should carefully choose the best procedure for the cutting of your products.

Testing Prototypes

Before availing of the whole service or buying the products in bulk, testing prototypes is always a safe hand.

A rubber prototype 3D print would make things easier for you to understand before you make a final selection for production.

Considering Hollow Sections

A product having a hollow part could be a cost-effective solution for rubber extrusions.

This retains the same compression value while using less material, resulting in a cheaper ultimate cost.

Most manufacturers make fenders and gaskets with hollow parts, which is a wonderful option for a variety of applications.

9. What Is Extrusion Die For Extruded Rubber?

An extrusion die is something that is made by cutting a hole in a blank of steel to use as a tool that has the major role for precision.

These dies are thick, circular steel discs with one or more apertures that allow the desired profile to be created.

They’re often made of H-13 die steel that’s been heat-treated to withstand the pressure and heat of hot aluminum being driven through the die.

The opening will be shaped to fit the desired finished rubber cross-section for an extruded item.

Once in place of its requirement, the rubber material will be driven through the die by the pressure generated by the extruder’s revolving screw.

Many rubber compounds inflate or swell as they pass through the extrusion die, causing them to expand and grow in size.

While aluminum appears to be a soft metal, pushing a solid log of aluminum through a thin, multi-holed die to obtain the correct form requires a huge amount of pressure.

In fact, pushing a billet through an 8″ inch press requires 100,000-125,000 psi of power.

This is a lot of pressure that handles the extrusion press process.

10. How Long Will Rubber Extruded Products Last?

A rubber extruded product has 5-10 years of life. This time span can vary depending on the type of material used in the production process.

For Silicone, Viton, and Fluorel, the rubber extruded products are expected to last around 20 years.

For Neoprene, Butyl, Nitrile, EPDM, and NBR, the lifespan of rubber extruded products are expected to last for 5 to 10 years.

For SBR and natural rubber, the life span is around 3 to 5 years.

11. What To Consider Before Choosing A Rubber Extrusion Manufacturer From China?

There are lots of rubber extrusion manufacturers from China, and each of them has its own production procedures.

You must collaborate with a high-quality manufacturer to obtain a high-quality product.

Testing the quality of each of the manufacturers is one crucial step.

Great companies prove their worth by delivering the best quality products numerous times to the customers.

To choose from among them, you need to look at their business profiles and intend to talk to their employees.

You can share your requirements, specifications and demands with the employees to learn more about their services.

Remember to ask about the order volume/quantity, price, and delivery date.

Each conversation should be compared and contrasted.

Determine which supplier provides the best deal as well as the finest customer service.

It’s preferable to avoid a company that doesn’t provide exceptional customer service, as miscommunications can lead to a loss.

Reach out again and get started once you’ve determined which source is right for you.
