The production process of silicon wafers is challenging and the equipment represents high-quality technology. The factory has various machines and devices that require continuous maintenance in order to guarantee high quality. The main development targets include the realisation of scheduled maintenance and continuous content development as well as reliability and productivity. 


Caverion’s professional maintenance technicians work mainly in two shifts. Each technician has their own limited responsibility for equipment and the technicians take care of the scheduled maintenance of their own equipment independently, i.e. malfunction repairs and spare part orders. 
The realisation of scheduled maintenance is monitored together on a daily basis in every morning’s production meetings in which daily work tasks are prioritised according to the production flow.  
In addition, the precautionary safety at work plays a key role in all operations. 


The maintenance of Okmetic’s factory in Vantaa was outsourced to Caverion in 2006.
