OC-System was established in 1992. We purchased our first powder-coating facility in 1997 and immediately discovered the benefits of powder coating over other surface-finishing techniques. Our original powder coating line components included a washer, oven and a spraying booth. We used the same oven both for drying and curing.

In the autumn of 2015, we dismantled the old line, removed the spraying booth and oven, and invested in a new powder coating facility. Our new facility includes an automated powder coating system, spraying booth, and separate ovens for drying and curing. In addition, we replaced the old manual guide rails with an automated conveyor system. Our new powder coating line includes an iron phosphate washer. The drying oven is followed by an automated spraying booth with effective powder recovery system. This modern powder coating line is designed for manufacturing industry. Only a few powder coating lines of this scale are installed in Finland annually. The conveyor systems were manufactured by Nipema Oy and the powder coating system was delivered by Wagner Industrial Solutions. Our powder coating meets corrosivity category C3/M.

We use both polyester and epoxy polyester powder coating in RAL colours. Special colours are available by special order within a week.

When we established our company in 1992, we first invested in an Esab welding robot. It served us well until 2005, when we replaced it with ABB's IRB2400 welding robot and IRBP 500K positioner that rotates the workpiece. The robot is equipped for Mig/Mag welding and has an arm reach of 1500 mm. The positioner can accommodate a workpiece with the following maximum dimensions: length 2400 mm, width 1200 mm and height between 100 mm and 500 mm, depending on the width of the workpiece.
