KPMI Quality

KPMI's objective is to supply consumers with products that function correctly the first time and deliver the best value for money in terms of reliability and performance. None of their products reaches final approval without first enduring a development flow procedure. Three signatures from engineering and one from production are required for final evaluations. This means that each product undergoes three independent assessments throughout its development process before a final product is launched.
