Technical cleanliness is especially crucial for all electrical and metallic components. Even the slightest particle contaminations can have serious consequences such as short circuits, leading to recalls. Especially in the automotive industry, but also in the electronics industry, technical cleanliness is indispensable in production processes. While in the past, a side mirror functioned without electronics, today it comes with a variety of electrical components: electric adjustment, heating elements, sensors for accident prevention, and camera systems. Technical cleanliness is essential for flawless operations.
