Temporary insulation with polyurethane foam

Masking parts with Tetrafluoroethylene (TFE) tape allows easy removal of insulation; therefore, insulation can be used temporarily while testing of parts and then removed for their reworking.

Cryogenic machining of polyurethane foam

Low-density foam can be machined precisely while frozen. Liquid nitrogen cools foam and aluminum heat sink prior to machining. Heat sink keeps part frozen during entire machining operation.

"Grinding" cavities in polyurethane foam

Grinding tool installed on conventional milling machine cuts precise cavities in foam blocks. Method is well suited for prototype or midsize production runs and can be adapted to computer control for mass production. Method saves time and materials compared to bonding or hot wire techniques.
