Process Control

Definition

Process control refers to the methods and technologies used to manage and regulate manufacturing processes to ensure product quality and consistency. It involves monitoring variables such as temperature, pressure, and material flow, allowing for adjustments in real-time to maintain optimal conditions during production. Effective process control is critical in roll-to-roll processing, where continuous material handling requires precise management to produce reliable and high-performance flexible electronic devices.
