Abstract
PURPOSE: To secure fitting of a door packing in a refrigerator door simply from pushing the door packing in a fitting groove which is formed on the door to have an undercut effect through embedding an elastic projection in a die.
CONSTITUTION: A refrigerator door 1' provided with a fitting groove 18 having an undercut effect is formed by injecting urethane resin dies 13, 14 in which an elastic projection 16 like urethane rubber is embedded. The urethane resin consists principally of polyol and isocyanate and is characteristic of forming a foam adiabatic zone with a low density internally and a skin layer with a high density in the covering. Thus an undercut part almost similar to the elastic projection 16 can be formed. A secure fitting is obtainable from pushing a door packing in the fitting groove 18.
