The rubber extrusion seals normally are acquired from CR, NBR, EPDM, NR and SBR among others. It is obtained by microwave curing process. During the rubber extrusion process, rubber is fist thrown inside an extrusion machine using a shaped die. This die gives it the wanted design and shape.
The process involves a lot of pressure and the end product can be customized to be used in many sealing applications such as manufacturing, electronics, cleaning, flooring, aerospace, industrial appliances among other uses.
The End Products
The finished products of the rubber extrusion process are rubber seals used in containers, rubber trims, window glass seals, doors and so on. There is no doubt that these materials are the best when it comes to sealing. This is solely because they have great resilience; they are practically impenetrable and also flexible.
Other uses of these finished products are; they are used in manufacturing facilities, used as rubber rollers to absorb noise in moving parts. The quality of the finished goods depends on the material used and the rubber extrusion process applied by the rubber extrusion manufacturers. It is potent to note that rubber comes in distinct forms and therefore undergo different extrusion process from each other.
• Natural rubber. This is the most common type as people prefer it over the others. This is because it has qualities that are really useful to the user such as strong resistance to abrasion and acids.
• Silicon rubber. It is also used since it does not react to fluids and not affected at all by temperature.
• Viton rubber. This rubber is also very resilient when it comes to chemicals, weather or heat. It is majorly used in the food industry and healthcare.
• EPDM is retardant to UV, ozone and heat. It is used in various platforms such as gaskets, door seals, roofing and weatherproofing.
Custom EPDM rubber extrusion is accomplished by the use of an extrusion machine. The rubber that has been extruded is then passed through a design stage where the right rubber material is chosen and a die is produced. The rubber may be cold fed or heated prior depending on what it will be used for.
The rubber is fed to a hopper using the help of gravity and then forced to sink down. The conveyor then moves the rubber towards the die. This aided by pressure and temperature that comes from the screw.
Rubber is now softened and fed to the die in order to have the required shape and design. You can decide to perform some post-processing tasks such as cutting, dusting, drilling and vulcanization.
Relevance of Rubber Extrusion
The extrusion of rubber is quite potent in a number of ways. The very first advantage is that there are no restrictions in how you want to design the rubber. You are able to produce the different forms of rubber in distinct sizes and shapes of the material that you are producing.
This basically means that you have a variety of choices to choose from in the materials that have been extruded. Another great advantage of the rubber extrusion process is that the results are soft, flexible and strong materials.
