How Rubber Extrusion Process – Rubber Cord,Tubing,Coextrusion,Extrusion

The Custom Rubber Extrusion is primarily accomplished with the aid of microwave curling procedure. During the specific procedure, the rubber is known to be fist thrown inside the extrusion machine with the use of shaped die which is useful in conferring the required shape and design. A wide array of pressure is required for conducting the procedure. It is possible to customize the end product in a bundle of sealing applications like electronics, manufacturing, flooring, cleaning, industrial appliances, aerospace, to name a few.

A guide to the extrusion process

The extruded rubber products are known to be different from the molded rubber products. The extruded parts are known to force under extensive pressure of the extruder via the required cross-section die by the China Rubber Extrusion Suppliers for the manufacturing of the products. They are composed of unvulcanized and soft rubber compounds which are fed in the specific extruder. The hardening or vulcanization of the end extruded products is required before they become usable.

Working of rubber extrusion

The procedure of rubber extrusion is known to start with the rubber compound which is fed in the extruder. The next step involves feeding of materials in the feed hopper after which the material is used and fed into different flutes, present in the revolving screw. After this, the screw will start carrying the rubber into the die forward with the rise in the temperature and pressure as the material goes close to the die.

The vulcanization process

As the material is found to reach the specific die, the material is forced by the in-built pressure via the openings. In this step, it is known to swell to different degrees consequently based on hardness and material compound. As it tends to swell, different extruded parts need more or fewer tolerances of the cross-section. During the vulcanization process, the extruded rubber undergoes shrinking or swelling in both the length and cross-section which is dependent on the kind of rubber compound, that is used in the process.

Once the vulcanization process is over, the rubber extrusion length tends to decrease in the length center in dimension, in comparison to the ends.

What are extruded die

The extruded die is recognized to be a specific and precise tool which is manufactured by cutting a certain opening via the blank of steel. Here, the opening shape is known to match the finished rubber cross-section which is desired for the extruded part. As it stays in place, the rubber material will be found to force via the die with the aid of the pressure which tends to be built from the extruder revolving screw.

There is a wide array of rubber compounds with a swelling tendency at the time of passing via the extrusion die. It may lead to a rise in the dimensions. In this way, the dies are manufactured as per the specific material and parts, thereby ensuring that the tolerances are completed for those specific finished extruded rubber part.

There are different benefits of the rubber extrusion procedure. They are known to be highly effective and involve a reduced cut off from the pocket. You can avail them in a wide assortment of shapes from the Rubber Profile Suppliers. In addition to this, they are lighter in weight and flexible at the same time.
