The elasticity, flexibility and resistance property of rubber are among some of outstanding properties of rubber that makes it suitable for a number of uses. It is used in the production of various objects and machineries air hoses, rainwear, diving gear, processing equipments. Also due to the resistance properties of processed latex to water and other fluids it is used to manufacture gears used during rains. All these processes make Rubber extrusion and processing an important process.
The raw matter is also called Caoutonic or Indian rubber. There are also those synthesized that are manufactured in industries using petroleum products. The constituents of organic compound are referred to Polyisomers which are isoprene Polyisomers. Natural or Indian latex is normally extracted from trees and is usually in a milky sticky form referred to as latex.
The raw latex usually undertakes different operations like mastication, mixing, calendaring and extrusion. Extrusion refers to the process where objects are usually used to create objects of a fixed cross-sectional profile. Extruded products are usually different from molded material because of process that they are commonly under the pressure of an extruder and passed through a die of the required cross-section.
The feeding of processed rubber that is uncalvinised into an extruder is usually the first process in Extrusion. The flutes of revolving screws carry forward the matter into the die where the temperature and pressure are normally slightly higher. The unprocessed latex is passed through the openings with the pressure being applied.
The swelling of the substance once it is in the openings in the machine it will swell in different angles depending on the compound of the material and how hard the nature of this material is. Because of this swelling tendency various extruder parts are mostly fitted with an extra tolerance capability on their cross-section to allow a plus or a minus during the swelling process.
Various shapes are generated by specific and special tools which are exceptionally designed for the job and are referred to dies. Different types of materials and their parts are selected just before extrusion process, and analyzed to make a determination as to whether they are in accordance or are able to meet the tolerance capability of the extruder.
When vulcanizing the material, the extruded substance length will be reduced in dimension more in the center of their ends. There are different cross-sectional tolerance classes for processed latex extrusions. The closer tolerance classes are not usually specified and are only classified unless the final application to do so, and are normally restricted to the critical dimensions.
When the extruder is involving in cutting the material it is normally advised that control must be exercised according to the closer dimensions which normally results to a greater cost. The measurements are normally in millimeters with a higher precision and normal precision. The materials usually softer in nature, those that demand a post cure usually have a greater tolerance capability.
