Abstract: The purpose is to find the optimal process conditions for the diaphragm rate of change using the design of experiments. Input variables are temperature, delay after pressure, degassing, and input amount, and output variables are outer diameter, inner diameter, depth, and thickness. A non-repetitive factorial design was used to investigate the effect of input variables on diaphragm dimensions. The regression equation obtained from the significant terms showed that the depth of the diaphragm decreased with higher temperature and more degassing. Response optimization was used to determine the optimal values for each factor to achieve the target dimension. The rate of change was calculated to mould the diaphragm into a desired dimension, and the obtained result is expected to have high reproducibility as it has a high R-square. This method provides a useful method for accurately manufacturing diaphragms using a new mould based on the obtained rate of change.
