Foamed casting is a simple non-mechanical version of pouring (Chapter 11), reaction injection molding (RIM) (Chapter 12) or liquid injection molding (LIM) (Chapter 16). Liquid components of the plastic with... 

SENSITIVITY - Sensitive to one 6 blasting cap at densities of. 95 G/cc or less. This foamed cast explosive is sensitive to a dynamite booster at a density of 1.25 or less. These figures are applicable at a charge diameter of 2 inches (5 cm.) or greater.

This process, commonly called "Lost Foam casting , was developed 30 years ago and its commercial growth was initially rather slow. However, during the last 10 to 15 years, it is has become used more often, primarily for the mass production of automotive parts or similar products, in spite of significant set-up difficulties. 

Alternative moulding/core-making methods Lost Foam casting... 

The general principles of Lost Foam casting have been described in Section 2.5.7.1. Due to the absence of binders, the technique produces a reduced amount of solid waste and emissions compared to sand casting methods.
