Automotive manufacturing is the quintessential dirty industry. I always picture mechanics with oil and grease on their hands wearing beat-up clothes and boots, and have also assumed that making car parts is just as messy as fixing them. Turns out I am right, which is why automotive parts washers are in such high demand. Automotive manufacturers do not only craft vehicles for public consumers, but also create vehicles for construction, agriculture, aerospace and manufacturing industries, so they have a lot of work to do. Part of the process involves ensuring that when a vehicle is complete, everything within it is shiny and new, which is aesthetically pleasing but also, more importantly, a sign that everything will work properly for a very long time.
Parts that have gone through automotive parts washers during manufacturing are parts that are pristine and therefore able to be treated further without risk of the treatment not working because of dirt or debris. It is also necessary in automotive shop settings when fixing older systems, because a filthy part is not going to be a good addition to a renewed vehicle system.
A variety of automotive parts washers exist because they are only referred to as automotive parts washers when they are washing automotive parts. Otherwise, they can be used to wash a variety of other pieces and parts form other industries as well. The parts washers that are often utilized in the automotive industry have a couple major styles; aqueous parts washers and ultrasonic washers. Aqueous parts washers are usually operated in cahoots with a conveyor belt that cycles parts through a cabinet of sorts where cleaning solution and water are sprayed out of high-level jet nozzles, removing everything from the material. Ultrasonic models utilize more high tech techniques for particularly delicate automotive parts.
