What Hein Lehmann does

HEIN, LEHMANN is a German industrial manufacturer founded in 1878 in Krefeld, Germany, specializing in screening, separating, and conveying technology for industrial process applications. The company operates as part of the hl.group holding structure, is described as family-run, and employs 501-1,000 people. It serves a horizontal mix of industries including stone and earth, food, chemical, pharmaceutical, automotive, plastics, and recycling sectors, with a stated global reach via direct enterprise sales contacts.

The company's product portfolio is organized around five categories: perforated plates (including the proprietary CONIDUR® line with triangular and semi-elliptical micro-perforations), wedge wire screens (RIMA® welded and CORIMA looped), wire conveyor belts, LIWELL® screening machines built on the proprietary Spannwell® principle, and raw material screens in wire, Vibro-Flex, polyurethane (Lemanit), and rubber base materials. Its core technical differentiator is the Spannwell® screening principle — described as the world's first of its kind — which has been deployed globally for over 40 years for difficult and moist bulk materials. The company also cites 70+ years of metallurgical expertise in wire conveyor belts and holds registered trademarks across CONIDUR®, LIWELL®, RIMA®, CORIMA, and Spannwell®.

HEIN, LEHMANN operates a consultative, direct enterprise sales model selling custom-engineered hardware. Pricing is quote-based and tailored to individual customer specifications, with revenue generated primarily through hardware sales of bespoke components and machines, complemented by after-sales management. The company maintains global reach through direct enterprise sales contacts, participation in trade fairs (POWTECH 2026, Scrap Expo USA, VOCATIUM), a multilingual website (DE/EN/ES/FR/NL), and a content-marketing approach anchored by application case studies branded as "Short Stories."
