also the development of appropriate rubber compounds is required, which is handled by our central factory laboratory. the center develops technical documentation, compiles a mathematical model and puts the tire into production and manufacture of the tire. this is a very complex and cumulative work of all workers. tire it consists of many parts 10 or more due to the manufacture of each detail is a huge technological process. the manufacture of any tire at any of the plants begins with the receipt of raw materials to the plant in total about 70 different chemical ingredients are supplied. the main ones are carbon black, kolchaks, natural and synthetic bags in english called big bags, carbon black is supplied to us at the enterprise. approximately 35 different codes for rubber compounds are used. each rubber compound has its specific purpose, based on its performance qualities. we threw in the ingredients after they were mixed and formed these rubber compounds with the help of an elevator. they went upstairs. and this is already going to say the first step in laying a new tire, the first foundation. af
