About JKS Engineering AG
JKS Engineering AG, headquartered in Nänikon (Switzerland), is an engineering and manufacturing company with around 80 employees. The group evolved from Neuma AG starting in 1995 and today comprises the business units Engineering, Solutions, Production and After Sales. Engineering develops special machines, test fixtures, gauges, automation and robotics solutions as well as electronics and control systems; the subsidiary and partner units ESORO (battery technology, hydrogen and fuel cell systems, vehicle development), Maprox (clamping solutions for metrology) and the iDIP platform for paperless production complement the portfolio. In Production, NEUMA AG in Wetzikon operates as a contract manufacturer producing turned, milled and surface-ground components – from one-off parts and prototypes to small series – including laser marking, Trowalizing, cleaning, product assembly and assembly technology. Precision clamping solutions are offered via JKS America in Whitestown, Indiana (USA). The JKS group is certified to ISO 9001:2015 and supplies industries such as mechanical and plant engineering, automotive, MedTech, pharmaceuticals, marine, and hospital & healthcare.
