NettetFor injection molding plastics, optimal wall thickness is given as a range of measurements in inches (in) and millimeters (mm). However, these … 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 …

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. Nettetto demould thick-walled parts safely without having to wait until they have fully solidified; it is therefore very easy to overestimate the nec-essary cooling time in such cases. …
