Yet, in drying applications from simple to complex, airflow and temperature uniformity makes a difference.

Seeking to develop a two-part polymer adhesive bonding step in their assembly process, a medical-device manufacturer in the northern United States performed extensive design of experiments (DOE) with multiple variables.
