Oskar Rüegg AG, based in Pfäffikon, Switzerland, is a globally active company in the supply industry. Founded in 1891 as a mechanical workshop, today it produces large series of highly complex molded parts using stamping, bending and deep-drawing techniques from aluminum, rust-resistant steels and non-ferrous metals, as well as assemblies. They are used in the automotive, audio, lighting, electrical and electronics industries as well as in mechanical engineering and the construction industry. A large proportion of the metal molded parts we manufacture go to so-called Tier 1 suppliers to the automotive industry.
These include many visual and functional parts for the lighting unit, such as beam shields, reflectors or housing shells for the electronic control of the headlights, explains Monika Schibler, who is responsible for maintenance, environmental management and occupational safety at Oskar Rüegg and is integrated into the decision-making process in the case of special tasks. These special tasks also include parts cleaning. Before the workpieces are delivered or assembled into modules, the adhering punching oil must be removed. For this purpose, the company uses a modern, environmentally compatible VAIOCS (Vacuum Assisted Inorganic Organic Cleaning System) continuous cleaning system from EMO Oberflächentechnik.
It works under vacuum and is operated with DOWCLENE 1601, a non-chlorinated solvent based on modified alcohols. In order to meet the different cleanliness requirements, the process steps spray cleaning, immersion cleaning, steam degreasing and drying as well as the rotating and swiveling movements of the cleaning basket can be selected via programs stored in the control system.
