The project of "Reducing Water Consumption of Hard
Disk Substrate Grinding" is designed by Kaifa Precision. They took some
improvement actions, including shortened pickling spray time, improved grinding
flow rate, intelligent control over the operation of box washing sprayer, and reduced
nozzle size of the refiner. These actions can help to reduce the water
consumption per thousand substrate discs by 26%, leading to water cost saving
of nearly 3 million yuan per year. Based on this project, Kaifa Precision obtained
an invention patent and the title of "Excellent Cleaner Production
Enterprise 2019-2020", receiving both economic and environmental benefits.
