MOLD HAVING AN INSERT FOR MOLDING BATHTUBS, A METHOD OF MOLDING THE SAME AND A BATHTUB MADE BY SAID METHOD

摘要

A mold for making bathtubes is disclosed. The mold includes a mold receptor and an insert attached to the mold receptor face. The mold receptor receives a shell which has a finish side and a non-finish side. The shell is placed in the mold receptor leaving a void between the non-finish side of the shell and the face of the receptor. The insert is attached to the face of the mold receptor to reduce the cross-sectional area of a portion of the space between the shell and mold receptor face. A male mold engages the finish side of the shell, sealably retaining the shell to the mold receptor. A polymeric foam material is introduced into the void between the receptor and the shell. The polymeric material fills the void and coats the shell. The molded bathtub is then removed from the mold receptor after the male mold has been removed. The insert is then removed leaving an area of reduced thickness and a periphery on the non-finish side of the molded bathtub which defines a lip.
