About us
LEPPIN Maschinenbau is a mechanical and tool engineering company founded in 1960 and based in Trier (Rhineland-Palatinate). The owner-managed, medium-sized family business manufactures CNC turned and milled parts for industry, welded constructions from steel and stainless steel (MIG/TIG), broaches keyways to DIN 6885 and produces prototypes, functional parts and small series using industrial 3D printing (Raise3D Pro3 Plus HS, build volume 300 × 300 × 605 mm). The portfolio also includes the design of complete conveyor systems and special machinery, manufacturing to customer drawings, spare parts production and procurement, assembly of mechanical and pneumatic assemblies as well as an on-site repair service. Core products are conveyor technology (roller conveyors, rotary stations, elevators, pallet conveyor systems up to 1.5 t), flat belt transporters, tobacco feeders, pallet lifters and labelling machines. Customers come from the food and beverage, tobacco, cigarette, drinks, cardboard and wood industries as well as from mechanical and tool engineering.
