SPC
SPC stands for Statistical Process Control and refers to statistical process monitoring or process control. This involves systematically recording and statistically analysing selected quality and process characteristics during production.
The aim is to identify variations, trends and changes in the process at an early stage. This enables causes to be investigated and measures to be taken before process changes lead to components falling outside the defined specifications. SPC thus contributes to stable manufacturing processes and reproducible component quality.
SPC in cold forming
In cold forming, too, SPC is used to assess the stability of the manufacturing process on the basis of defined characteristics. To this end, relevant quality and process characteristics are measured at specified inspection intervals, statistically analysed and monitored throughout the production run.
Quality control charts (control charts) play a central role in this process. They display measured values or statistical parameters derived from them over the course of the process. This allows trends, shifts or increasing variation to be identified at an early stage – even if the measured components are still within the specified tolerances.
At MN Kaltformteile, safety-, approval- and function-related characteristics in particular are monitored and documented using a CAQ system. The statistical analysis supports the assessment of process stability and provides transparency regarding the development of relevant quality characteristics.
SPC thus differs from a purely final inspection: the focus is not merely on whether a component meets the specified tolerances, but on whether the underlying manufacturing process is statistically stable and under control.
