[Case Study of Cleaning System Implementation] Cleaning of Thin Sheet Press Processing! Alternative to Chlorine-based Cleaning

Are you having trouble cleaning thin parts? The effectiveness of vacuum ultrasonic cleaning is significant! It provides a good working environment as an alternative to chlorine-based cleaning agents.

Company F mass-produces thin press parts, and after cleaning, these thin parts undergo assembly processes in-house to become finished products. Although the assembly machine was automated, it turned out that the parts we thought were being cleaned were not actually clean, and the automatic machine caused the thin parts to stick together, leading to blockages and difficulties. We had been using trichloroethylene (chlorinated solvent) for cleaning, but due to environmental regulations and its strong toxicity, we were considering alternative cleaning methods. By introducing a hydrocarbon-based cleaning machine that takes into account human health and the environment, we improved cleaning efficiency, resulting in increased productivity. **Challenges** - We do not want to use trichloroethylene due to its toxicity and environmental regulations. - Thin press parts are sticking together and cannot be cleaned. - The takt time is about 3 minutes, but with re-cleaning and other factors, capacity is at its limit. **Results** - Achieved environmental compliance by using hydrocarbon agents. - Performed vacuum ultrasonic cleaning, which effectively cleaned between the thin sticking parts. - By using two drying chambers, we achieved a takt time of 3.5 to 4 minutes. *For more details, please refer to the PDF document or feel free to contact us.*
