Trend-setting changes at Schlumpf

For more than 60 years, Schlumpf AG has been one of the most significant manufacturers of high-quality mandrels, expansion shafts and other winding elements. As a manufacturer of customer-specific special constructions for demanding applications, we have made a name for ourselves in particular thanks to our many years of practical experience. We are passionately developing winding technology further on the market, keeping our eyes and ears wide open in order to allow you to achieve optimum customer benefits.

Thanks to the additional branch in southern Germany built in 2018 - with in-house production facilities - we can now serve our international customers with even greater capacities and more flexible services at the highest quality. The cross-border assembly site also ensures simpler processing of service and repair orders for the entire EU area, thus eliminating Swiss customs formalities.

Portfolio expansion with expansion shafts    

Following the restructuring and focusing on the mandrel business in 2015, Schlumpf AG is now expanding its product range once more to include further developed expansion shafts. Starting in 2020, Schlumpf AG will once more be supplying its customers with its many years of valuable expertise in the area of expansion shafts, in order to again fulfil holistic customer wishes in the area of custom winding technology.
The expansion shaft portfolio includes proven, robust and reliable CTA/S and CTC/S, our lightest Mono Grip expansion shaft in the 3 and 6 inch versions as well as the high-performance mechanical expansion shaft type SF. We will now also offer the SF version as SFA and SFC. These are based on the principle of the proven CTA and CTC shaft, but in the mechanical SF version.
