Higher Yield with stabilization of manufacturing processes
A stable process is predictable – not dependent on individuals – on-time - measurable - reproducible and it may be traced back unambigeously. The reverse argument tells you that the productivity of your company suffers from disruptive processes if only one of the following statements applies:
- Yield depends on the physical and mental "state of the day"
- Products and processes are randomly out of spec
- On-time delivery is "by and large" o. k.
- Never ending arguments about the "right approach"
The approach
Complex sequences of high tech processes require an in-depth approach to process stabilization. Due to their wide scope proven methods like Six Sigma and CIP fall short to yield lasting improvements in this domain.
CIM Aachen recommends Integrated Process-Management (IPM).
Based on a detailed manufacturing reference model the processes are first stabilized and then optimized.
Who needs IPM?
IPM yields substantial improvements in the following domains:
- Smelting-, Casting- and Rolling operations,
- Coating, Painting and Heat treatment,
- Chemical-, Pharmaceutical and Food Processsing.
Systematic one-time effort replaces ongoing losses
IPM: First stabilize – then optimize
Higher Yield from stabilized manufacturing processes
Stabilization of processes is synonymous with productivity increase. CIM Aachen’s experience from various projects shows:
- Yield increase by up to 15%,
- 20 % higher share of productive machine hours,
- increase of on-time deliveries up to 12% and
- improve of "in-spec"-rate by 35%.
