  • disposes a subcontracted processing for mechanical precision parts


  • 1925 founded by the fine mechanics foreman Wilhelm Koch in Frankenthal/ Germany
  • first specialized in the production of water meters
  • possessed a foundry, turning lathes, assembling and testing system
  • a significant patent of water meter techniques led to profitable advantages
  • prominent in those days, Koch opened up international markets all over the world
  • 1958 his son-in-law, engineer Dipl.-Ing. Helmut Neuburg, joined in the company
  • introducing of further products like sight glass armatures, flow indicators and full flow filters for pump manufacturers, power plants and chemical industries
  • particularly increasing of the machinery and capacity of fabrication
  • Neuburg established the mechanical subcontracted processing
  • 1988 handing-over to his daughter, engineer Dipl.-Ing.(FH) Annette Neuburg-Linnebach
  • innovations in manufacturing procedures with modern machines controlled by CNC and CAD for engineering and design
  • development of new products for filter systems and plasma deposit welding
  • optimized the fabrication of existing products
  • computerized manufacturing planning and order processing
