Sundwiger Messingwerk

Project outlines

Sundwiger Messingwerk GmbH & Co. KG is among the leading manufacturers of high-performance copper alloys for electrical-engineering and electronics applications. In addition to strips and wires for plug connectors used in the automotive and telecommunications industries, scatter-sintered heavyduty friction linings for clutches and brakes are also developed and manufactured. Lastly, special deep drawing qualities for cups and leaded nickel silver for ballpoint pen refills round off the product portfolio. Strips of excellent stamp ready key blanks made to extremely tight tolerances are delivered directly to the coin and key manufacturers.

Saving energy now also means improved safety!'

To maximize product versatility and enhance customer satisfaction, Sundwiger Messingwerk has fully integrated its production departments for melting, rolling, drawing and finishing at one location. After the acquisition by the Diehl Metall Group in 1958, the company focused even more on quality, not on mass production. Sustainability and environmental care were always integrated into management guidelines. The expression 'Sundwiger Quality' is well known with its growing base of German and international customers. An audit was organized to improve the lighting network at the facility. The report showed that the replacement of the outdated 700W magnetic HID with a Nedap Luxon e-HID 400W system would deliver significant energy savings and improvement of the lighting quality in combination with CO2 reductions. Requirements for wireless dimming to allow for full product flexibility such as lamp grouping and task-specific lighting settings can also be achieved with this platform.
