About NESPER
Egon Nesper GmbH & Co. KG (NESPER) is an independent family business founded in 1957, headquartered in Ispringen (Baden-Württemberg) with further locations in Germany and the USA. The company manufactures high-precision stamped parts, contact rivets and contact parts, stamped grids (leadframes), busbars, press-in zones (EloPin®) as well as complex plastic hybrid components and assemblies. Core processes are precision stamping on more than 60 automatic stamping presses, fine blanking, laser cutting, the pre-molding of position-oriented metal parts (plastic hybrid technology) and mechanical joining such as riveting, clinching and interlocking. These are complemented by downstream processes such as inline cleaning (NESPER-Cleaning©), vibratory finishing, inspection and packaging. Design, toolmaking and tool takeover are carried out in-house, from prototype production to high-volume series. Customers come from automotive, electrical engineering/electronics, medical technology, power electronics, e-mobility, hydrogen and fuel cell technology as well as energy technology.

Materials & Processes
Precision stamping
High-precision stamped parts from small series to several million pieces on over 60 automatic stamping presses.
Fine blanking
Fine blanked parts with tight tolerances for demanding contact partners.
Laser cutting
Laser-cut sheet metal parts for prototypes and series parts.
Plastic hybrid technology
Pre-molding of position-oriented metal parts with plastic, also media-tight, for production-ready hybrid components.
Riveting technology
Solid and bimetal contact rivets, produced since 1957 on self-developed machines.
Press-in zones (Press-fit)
Reliable press-fit connections without soldering for power electronics.
Bimetal
Bimetal contact rivets and contact parts for switches, relays and sensors.
Copper
Contact parts and busbars for high currents and electrical power.
Plastic
Overmolding for hybrid components in automotive and electronics.
NESPER-Cleaning©
Inline cleaning of stamped parts as a downstream process.
Vibratory finishing
Tumble deburring for edge refinement and surface finishing.
