Nettet29. des. 2014 · It has been explained above, and it can be seen in the sidebar, how multilayer molding can increase the profitability of production of thick-walled parts. It takes advantage of the fact that several thin layers will cool more rapidly than one thick layer. This can increase productivity by approximately a factor of two. Nettet27. mai 2002 · Part design requirements for the different types of PP are the same with the exception of wall thickness. PP's wide range of melt indices (MI) must be taken into account. Not all PP can be molded in the same size and thickness part. A 2-MI PP may not fill a part designed to be molded in a 10-MI PP. See below for other design …

It describes the extent to which the material changes in … NettetA minimum thickness for dip coating is achieved during the crossover between these two coating regimes. As the withdrawal speed goes away from the minimum in either direction, the different coating regimes dominate. For high and low speeds, the thickness curve can be given by either the Landau-Levich equation or the capillary regime equation alone.
