Standard parts often utilize raw materials that meet basic chemical composition requirements. In the Juq379 process, raw materials are screened for microscopic impurities. For example, if the component is a steel alloy, the "Extra Quality" version undergoes spectro-graphic analysis to ensure that trace elements—such as sulfur or phosphorus—are kept to an absolute minimum, reducing the risk of metal fatigue or corrosion over time.
However, the foundational principle remains: is about data integrity. It is the refusal to accept "good enough" in favor of "as close to the original source as technically possible."
