The Challenges and the Solutions

SFC Excellence had been manufacturing lubricants blending manually, and faced many challenges during daily operations such as: long process times, low flexibility of recipe management and the inefficiency of raw components movement. These challenges had been directly linked to the productivity, profitability and safety of operations at the lubricant plant, and the company decided to change from manual to automated operation plant in 2012.

SFC Excellence selected Yokogawa because of Yokogawa's rich experience in meeting customer's requirements in lubricant manufacturing industry. Yokogawa successfully installed FA-M3, a cutting-edge controller, to automatically control the blending process in the lubricant plant, such as, base oil/additive movement, batch blending and filling.

The company also uses Microsoft AXAPTA for Enterprise Resource Planning and recipe management to maintain over 1500 recipes. Yokogawa provided interface to integrate information between FA-M3 and AXAPTA. By receiving production scheduled orders from AXAPTA, the control system can automatically execute orders with minimal operator interaction. Additionally, after a batch blending is accurately completed, the production results are electrically available to the operator, and uploaded to AXAPTA.
