Galvatek has delivered a surface treatment line for aluminium components to the Ouneva factory in Tuupovaara, Eastern Finland. The new automated line is designed to apply electrolytic tin to aluminium cable connectors. Ouneva’s connectors are used in distribution boards, and approximately 70 percent are exported.
“The new surface treatment line delivered by Galvatek represents the single biggest equipment investment in Ouneva’s history. The installation process was the smoothest we have ever experienced,” comments Mikko Nevalainen, CEO of Ouneva Group.
Galvatek previously delivered a copper surface treatment line to Ouneva’s Tuupovaara factory in 2013. The new aluminium line is located alongside the copper line. Both lines share the same Galcont control system, and they both use the clean water, waste water and ventilation systems delivered by Galvatek in 2013.
The new fully automatic tin plating line utilises two hanging methods. Barrels are used for small parts and special jigs for larger aluminium parts. The waste water treatment plant uses neutralisation as the main processing method. The delivery included also an ion exchanger and a reverse osmosis unit. The Candovent ventilation system is powered by a wet scrubber and a ventilation fan.
“Galvatek is internationally recognised as a supplier of surface treatment lines for the aviation industry, but this delivery shows that we still serve domestic clients and those outside the aviation industry,” says Ulf Pråhl, Managing Director of Galvatek.
Ouneva ordered the aluminium surface treatment line in October 2015, and the line was ready by May 2016. Only eight months were needed from the time the agreement was signed to the start-up of the new line.
