摘要：
The invention relates to a method and a mould assembly for rotation moulding a pipe part (1) comprising a main body (2) and a spigot end (3), the spigot (3) end having at least one dedicated section (5) with an outer contour (6) that in use is to effect a close fit with an external part. At least during cool-off A support structure (8) is provided in the pipe part (1), at least during cool-off of said part, to keep the dedicated section (5) into contact with the mould (22) so as to have the outer contour (6) of the dedicated section (5) conform to the inner contour of the mould (22). The support structure may become part of the pipe part during moulding.
