MICRO-PROCESSOR BASED SYSTEM FOR CONTROLLING AND PROGRAMMING SACMI REFRACTORY PRESSES

摘要

Since the end of the 1950s, SACMI has designed and realized the control systems for all of its machines, including presses, mills and dryers. A study on microprocessor-based control systems was conduced at the end of the 1970s, and the first microprocessor system was installed on a manufacturing machine in 1984.The reliability of SACMI's microprocessor-based control equipment/PLC is illustrated by the approximately 8000 machines operating at the end of 2000. These machines are used in various fields, including ceramics, refractories, sanitaryware and packaging. The first models of some of those machines have been in use since 1984. More than 100 refractory presses operate with this type of control system.
