Harwin has invested in a new water treatment plant at its UK headquarters and manufacturing facility in Portsmouth, UK, improving the quality of finish of its plated parts and reducing the environmental impact.
Unlike many connector makers, Harwin is a vertically-integrated manufacturing company which keeps not only plating, but all other essential manufacturing operations under one roof. This enables the company to be very innovative and responsive. Utilising previous technology and due to the company’s strong growth, the company was using to 7,000 litres of water per hour; the new facility means that the company will use that same amount of water in two weeks.
The new plant which uses resin filter technology, supplied by PureTech, cleans all the rinse water and recycles it back into the plating area. In an industry first for tin, the heavy metals − gold and tin − cleansed from the water can be reclaimed.
