[Case Study of Cleaning System Implementation] Pre-cleaning before PVD Coating! Significant Reduction in Cleaning Failures

An optimal cleaning system for pre-coating that suppresses stains and cobalt leaching! High cleaning performance for oil holes as well! After cleaning, high cleaning performance without the need for hand wiping!

Company N is a business that provides contract processing for PVD coating. They handle various workpieces with different types of contaminants from a range of customers, applying coatings such as TiN and DLC to substrates like carbide tools (new and re-ground) and metal parts. Insufficient cleaning of equipment can lead to issues such as poor adhesion and outgassing, which are causes of coating defects. Traditionally, it was common to perform manual wiping with acetone after passing through the cleaning machine to avoid defects. However, after introducing "WS Emulsion Cleaning," they have been able to operate without manual wiping. [Challenges] - Manual wiping with acetone after cleaning is time-consuming. - The current cleaning machine has effects on the substrates (cobalt leaching, rust). - Managing the cleaning solution is difficult. [Results] - Improved cleaning performance has led to increased productivity without manual wiping after cleaning. - There is less impact on the substrates, making coating defects less likely. - Liquid management has become easier. *For more details, please refer to the PDF document or feel free to contact us.
