Designing an Accelerated Aging Protocol for Marks, Coatings and Bonds
A protocol is only useful if it fails parts the way service will. Choosing stresses, setting limits from material transitions and reading the results honestly.
FMEA for a Marking, Decorating or Pretreatment Line
Process FMEA works when it captures the failure modes these lines actually have. The ones that get missed, and how detection ratings hide invisible processes.
Cpk and Gage R&R for Mark Contrast and Adhesion Measurement
Capability numbers mean nothing if the measurement system consumes the tolerance. Measurement system analysis for contrast, adhesion and surface energy.
Writing a Marking, Coating or Adhesion Specification a Supplier Can Be Held To
Specifications fail when they state an outcome without a method. What to include so that both parties can reach the same verdict on the same parts.
When a Process Change Needs Revalidation — and When It Does Not
Treating every change as major stops improvement; treating none as major invites failure. A graded framework for deciding what a change actually requires.
IQ, OQ and PQ for a Laser Marking Process: What Auditors Actually Ask For
Validating a marking process means proving the window, not the setting. How installation, operational and performance qualification apply to laser marking.
