Abstract
A method for molding a thin walled plastic shell utilizes the following apparatus. An apparatus (40) for molding a thin walled plastic shell includes a mold box (42) having an inner mold surface (48). A powder box (52) includes an internal chamber and first divider wall (54) for separating the internal chamber into at least two sections (56,58). A carrier framework (60) is removably mounted on the mold box (42) and includes a peripheral seal for perfecting a seal between the mold box (42) and the powder box (52) when the same are connected thereto. A second divider wall (64) is connectable to the first divider wall (54) separating the inner mold surface into two chambers continuous with the two sections of the powder box (52). The carrier framework (60) further includes a mold surface seal (66) for perfecting a seal between the second divider wall (64) and mold surface (48).
