Development of an embossing process for micro-scale patterns of polypropylene films using statistical design of experiments (DoE) - A strategy to reduce the number of freedom in process settings to find the optimum

Process parameters are systematically varied, temperature, pressing-time, -pressure and the resulting step-heights are determined. Combining the direct correlation of step-height with its variation as a function of process parameters reveals most desirable process parameters. The approach described can be applied to a wide range of processing challenges.
