MOLDING DIE AND MANUFACTURING METHOD FOR SEAMLESS MOLDED PRODUCT USING THE SAME

Document Type and Number:

Japanese Patent JP2006281654

Kind Code:

A

Abstract:

To manufacture, without causing breakage and efficiently, seamless molded products such as gloves formed of a polyurethane resin.

The molding die 10 is the one having a molding face 11 and a non-molding face 12 formed on the outer surface and the one for manufacturing the seamless molded product comprising a polyurethane resin porous film by attaching to the molding face 11 a solution containing a water-coagulative polyurethane resin and by coagulating with a coagulant, and the molding die 10 is formed of a porous material equipped with through-holes which penetrate the molding face 11 and the non-molding face 12. By charging a fluid into the through-holes from the non-molding face 12 and discharging the fluid from the molding face 11 the seamless molded product can easily be peeled off from the molding face 11, which is efficient.
