Abstract

PURPOSE: To manufacure a heat-insulating wall having uniform foam density, ecocomically, with minimum raw material consumption, by poruing foamable raw liquid from a nozzle into a frame while traversing the nozzle relative to the frame.
CONSTITUTION: A stock liquid 11 of urethane foam 7 is poured from a nozzle 9 uniformly into a frame 1 while traversing the nozzle 9 to the direction of the arrow 10. Immediately after pouring, a release paper 12 is applied to the opening 2 of the frame 1, and the surface of the foaming liquid 11 is pressed with a mold. Before the solidification of the stock liquid 11, the pressing mold is lifted, and the foaming and solidification of the liquid is completed to obtain the foamed urethane 7. The foam 7 is assembled with an inner panel 4, magnet gasket 6, etc., to form a heat- insulating door of a refrigerator.
