Quality is not just a buzzword for us, but a consistent process with a decisive goal: “Zero defects” in every single work step.
In the mid-nineties, Tweer & Lösenbeck was one of the first screw companies worldwide to be certified according to DIN EN ISO 9001 and the environmental certification according to DIN EN ISO 14001 – followed by the automotive-specific quality standard ISO/TS 16949 in 2002. In order to continuously improve energy efficiency, the company’s energy management was certified in 2015. This was followed in 2018 by the conversion to the new automotive standard IATF16949.
This means that the company is now also certified in black and white: We manufacture and live quality that is consistently oriented towards customer benefit. An error rate of less than 50 ppm and reliable delivery promises are just two examples. We are not only continuously implementing this claim today. Tomorrow we will also face up to our responsibility for the environment and for the future of coming generations.
The screw factory Tweer & Lösenbeck was founded in 1919 and has been located in Lüdenscheid ever since. It has been owned by the Pithan family since the 50s. As a pure contract manufacturer, Tweer & Lösenbeck develops and produces small screws and fasteners for the most demanding requirements – several million pieces a day.
For Tweer & Lösenbeck, quality is not just a buzzword, but a consistent process with a decisive goal: Zero defects” in every single step of the production process! The company’s position as a quality and innovation company is to be maintained and expanded in the future as well.
