ABSTRACT:
A method and apparatus for stretch blow moulding a preform into a desired article is disclosed. The method includes the steps of inserting the preform into a hollow mould, stretching the heated preform with a stretching member, filling the preform with an incompressible fluid such that the preform expands and is formed into the article by the mould and draining the incompressible fluid from the interior of the formed article. The apparatus comprises a hollow mould for receiving the preform, a stretching member for stretching the preform, an incompressible fluid filling means for filling the preform with an incompressible fluid such that the preform expands and a drain for draining the incompressible fluid from the formed article.
