High-temperature, high-density epoxy-urethane foam
is an economical and time-saving solution for soft small,
monolithic or large-mass tools, as well as low-rate or rapid
prototyping. It can be more rapidly machined, it is
easily bonded, and it is more economical than wood,
alloy or epoxy-based alternatives. Common applications:
prototype machining, prepreg composite layup tooling,
vacuum form tooling, tool proofing, pattern making and
master model making.

Participants will learn:
• Soft Tool Properties • Tool Preparation
• Density Selection • Curing the tool
