Mould for the Spatial Shaping of Plastic Parts made of HDPE or PA or Similar Plastics, in particular HDPE or PA Tubes
The invention relates to a mould for the spatial shaping of plastic parts made of HDPE or PA or similar plastics, particularly HDPE or PA tubes, which comprises a body ( 1 ), which is provided with at least one contact wall ( 20 ) for contacting the mould with the shaped material. At least the contact wall ( 20 ) is made of a material with a thermal conductivity lower than 5 W·m −1 ·K −1 .

13 . A mould for the spatial shaping of plastic tubes, comprising:
a tubular body, the tubular body further comprising an internal shaping labyrinth in a form of a spatially shaped tube defining a longitudinal cavity, the tubular body comprising an outer spatial shape corresponding to the spatially shaped tube;
the tubular body comprising an open circumference along a longitudinal length thereof that defines a longitudinally-extending through-slot such that a plastic tube to be shaped in the mould is insertable into the longitudinal cavity through the longitudinally-extending through-slot;
the internal shaping labyrinth comprising at least one contact wall disposed for contact with the plastic tube inserted into the longitudinal cavity, the contact wall formed of a material with a thermal conductivity lower than 5 W·m −1 ·K −1 ; and
a plurality of circumferentially-extending flaps spaced apart along the longitudinally-extending through-slot of the tubular body at locations to retain the plastic tube within the longitudinal cavity.
