Patent CA-2435595-A1 (CA)
Title: One piece mold for a multi-piece tub and shower surround
Inventor: INGRAM SCOTT
IPC: A47K3/04
Filed: 2003-07-18
Abstract: A tub and shower surround assembly is initially molded as a single molded component having a waste strip which separates each individual tub and shower surround portion. The waste strip readily protects the mold and simplifies post molding operations and assures that each portion will meet final tolerances. Another waste strip is located between the tub portion and the wall portions to provide for positive draft between a tub flange which extends about the tub portion and the wall portions. Positive draft is required to assure proper removal of the mold component from the mold. The single component provides for finishing operations to be performed prior to separating the individual components. Since the majority of finishing operations are performed simultaneously prior to separating the portions, the likelihood of damage to the portions are reduced and the finish of the individual portions are of greater consistency.
