ABSTRACT:
A method for producing a lightweight end wall of a containers characterized by the following stages: manufacturing a large size lightweight thermoplastics tube by spirally winding and joining together a hollow profile of thermoplastics, cutting a piece from such a tube to form a pre-form of an end wall, heating the pre-form into a mouldable state, pressing the pre-form into a dome shaped piece between a male and a female mould-half, cooling the dome shaped piece while pressed between the mould-halves, maching-tooling the edges of the cooled piece to match the cross-sectional surface of the tube mantle, and joining the mantle and the end wall together by welding.
