Task

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

Industry/ Function / Environment

• Manufacturer of medical technology products
• Interim Project Manager
• Optimisation of production processes in platinum processing

• 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)
