Foam molding

From Plastics Wiki, free encyclopedia

erboctrocno Foamed plastics Process by foam molding or extrusion to achieve lower material densities for high rigidity, especially in large structural parts. Most processes for producing structural parts correspond to injection molding. To produce the foamed product, inert gas is dispersed through the polymer melt by blowing gas directly into the melt or by preblending with a chemical blowing agent, which releases inert as in the presence of processing heat.
