Process for preparing saturated polyester resin bottles |
摘要 |
This invention relates to process for preparing saturated polyester resin bottles, that the residual strain of the bottles is reduced and the deforming temperature is elevated. The process is that a heated intermediate material (1) made of a saturated polyester resin is set in a mold (5), then compressed air is blown in the intermediate material (1) to orient the same biaxially, temperature in thus shaped bottle is elevated to a temperature higher than the heating temperature of the intermediate material (1) under the elevated pressure to effect thermal fixing and thereafter the saturated polyester resin bottle (19) is taken out.
