Decorative plastics pot is produced in a mold by post-shaping a hollow preform, using inner heat to force its structure against the mold cavity wall, with moving half-shells for the molding space and molding removal

摘要

To produce a decorative hollow plastics pot, a post-shaping stage has the hollow preform (10) within a mold (20) with a mold cavity (30) giving the required pot shape. During post-shaping, the interior of the preform is heated by hot air or steam, without contact with the side wall (11). To produce a decorative hollow plastics pot, a post-shaping stage has the hollow preform (10) within a mold (20) with a mold cavity (30) giving the required pot shape. During post-shaping, the interior of the preform is heated by hot air or steam, without contact with the side wall (11). To remove the pot the mold has two half-shells (22) forming the hollow inner surfaces (225) when brought together, and be moved apart for post-shaping and separated for removal.
