The result is a continuous sheet of cord and rubber. This is cut at a defined angle to the correct length according to tire size and rolled up for further processing. Tread. Kneadable rubber material that has been blended in a mixer is now ready to be made into the tread. A screw-type extruder shapes the rubber into an endless strip of tread.
A flowchart is an umbrella term for diagrams that show the steps of any process. A workflow diagram, on the other hand, is a specific type of flowchart that visualizes the process of an organization using a standard set of symbols (diamonds for conditions, rectangles for actions, etc.).
The rubber may contract or expand during the process. Also note that the length of the rubber is also impacted after vulcanization. Meanwhile, the extrusion process is suitable for producing rubber in high volumes and the cost is also affordable. The products produced during the extrusion process include gaskets, tubing, cord and profiles.
