Designing the process - An introduction of multivariate statistic methods for rotational molding

Using experimental data or rotational molding, the multivariate statistic method of projection to latent structures or partial least squares (PLS) is used to determine the correlation between process parameters and various stages of the rotational molding cycle. In particular, strong relationships are found between the times required to complete various stages of the rotational molding cycle and the shape of the micropellets and the properties of the polymers.
