Method and apparatus for forming oriented, blown objects of moldable plastic material requiring prolonged tempering cycles to obtain conditions suitable for orientation. Disclosure provides a multiplicity of tempering molds in spaced relationship to each other for retaining and tempering parisons prior to orientation and blowing in a tempering cycle, whereby the tempering molds receive and release parisons seriatim, and whereby the overall operating cycle is substantially unaffected by the number of tempering molds.
