Abstract

Designed to shape large polyurethane hard foam sandwich components for aircraft and boat hulls, the hollow mould is supported at the sides by the casing flanges, and additionally by struts to the casing wall. The pressure system is fed into both sides to give equal pressures, through a control valve, while the foam is fed into the mould.
