Retrofitting lines built by other suppliers

Sixteen of the projects above are retrofits. Plants asked SREE to rebuild and upgrade cut-to-length lines in the 200 to 800 class that were originally supplied by other manufacturers, both European and Chinese. Rebuilding another builder’s line means reading its mechanics first, then re-engineering the shear, punch and feed sections around the existing bed.

Repeat business

Twenty-seven customers have placed three or more separate orders. The largest repeat account has placed 19 orders for 28 machines over four years. For production equipment, a second order from the same plant is the most direct quality signal there is.

Customer names are not published on this page. A reference contact for the project closest to your own product mix is available on request under NDA.
