Get to know custom rubber extrusions and how they are manufactured?

Custom rubber extrusions are produced using an array of rubber compounds which are fed into a rubber extruder. The rubber extrusion process begins with a rubber compound being fed into an extruder. The material is fed into a feed hopper, which takes the material and feeds it into various flutes in a revolving screw. The screw will begin to carry the rubber forward into the die, with an increase in pressure and temperature occurring as the material gets closer to the die itself.

Once the material reaches the die, the built-up pressure forces the material through the openings, where it will consequently swell to various degrees based on the material compound and hardness. Because of this tendency toward swelling, many extruded parts require plus or minus tolerances on their cross sections. During vulcanization, the extruded rubber will swell or shrink in both its cross section and its length, depending on the type of rubber compound used.

After vulcanization, a length of rubber extrusion will tend to be reduced in dimension more in the center of the length than in the ends.

Custom Rubber Extrusions and Seals Manufacturer from China

Custom rubber extrusions are widely used.

The reason why custom rubber extrusions are used is thatthet result in the production of soft and pliable rubber. The rubber made from the process is consistent and repeatable. It can be cut into different lengths to suit various applications. They are not like rubber molding that is usually restricted by press size where maximum straight length is usually one meter.

Extrusion is considered a cost-effective solution because it is easy to achieve bulk production. It is also possible to maintain a high level of accuracy in the process, unlike molding. Additionally, in case of aesthetics is desired, rubber extrusion makes it easy to do color matching.

Moreover, from the process, a variety of shapes can be created. The extruded rubber is lightweight and very flexible and can be used for different applications. They can also be designed based on customer specifications. Rubber extrusions are used for various applications ranging from sealing to noise reduction. Rubber extrusions are also used to create trimmings for use in mass transit trains. In modern architectural design, the material can be used for decorative purposes.
