Process optimisation wire production

Task

  • Cause analysis for unstable mechanical and electrical material parameters
  • Definition of an algorithm for tool change
  • Reduction of throughput times

Industry/ Function / Environment / Expert

  • Manufacturer of medical technology products
  • Interim Project Manager
  • Optimisation of production processes in platinum processing Dipl.-Ing. Volker Schreiner
  • Analysis of the melting, rolling and drawing process showed significant deviations from the target specifications in the process steps. Documentation standardised and regular controls introduced.
  • Tool wear 5-10 times higher compared to other producers. Suitable lubricant doubled the tool life.
  • Optimised lubrication conditions led to a doubling of drawing and rolling speeds, reduction of throughput times by 40%
  • Reduction of external machining of the tools. In-house machining enabled individual adaptation of geometries and surface qualities, tool life doubled again.
  • Tool change after assessment by the machine operator, elimination of the predefined change.
  • Participation in working groups of various associations enables better exchange of information
  • Reduction of production costs by >> 1.5 Mio.€
  • Reduction of throughput times by 40%
  • Stable production processes reduced fluctuations in mechanical and electrical parameters and scrap by approx. 30%
  • More decision-making powers for machine operators increased their motivation
  • German technology group with a focus on medical technology and precious and special metals
  • 14.000 employees worldwide, €21 billion turnover (2017)
