Abstract

PURPOSE: An air-removing part is formed between the depression on the back surface of the top board and the mold to remove air from the top board and the top surface of the sink, thereby producing top boards equipped with a sink with no void and good appearance.
CONSTITUTION: U-shaped depression 5 is formed on the periphery of cut space 4 for fitting sink on the back surface to top board 1 and gap 5' for removing air is formed between the depression 5 and mold 11. Sink 2 is set to top board 1 and they are placed on molding plate 9. Flexible material 12 is laid on the periphery of cut space 4 for fitting the sink on the top board 1 and flange part 6 of sink 2 and mold is placed on them. Mold is pressed and pressurized air is supplied to air bag 10. Under these conditions, a thermosetting resin for casting is poured from hole 13. The poured resin spreads in the direction shown by arrow a to fill gap t between hole 4 for fitting the sink and flange 6 and the air in mold 11 is expelled out of gap 5' in the depression 5 by the resin.
