The car wash industry grows with the development of automotive industry. In the beginning there were simple constructions compliant with the production technologies which were available. Thanks to years of development, today we have modern self-service car washes which require a high level of tehnological design and production. First of all, the terms of production will be described as some of the most important social function, realization of production and the purpose of the product manufacturing processes. Futhermore, the focus will be on the processes and technologies which are used in the making of construction of the self-service car wash. Basic technological processes and operations are both presented when displaying the manufacturing process. Lastly, a simulation of technological processes is presented, as well as a detailed explanation of the operations used in the making of a construction of the car wash „Omega“. The construction of the car wash was created with the purpose of a precise presentation of the parts and technological processes used in manufacturing.
